RAMCHARGER COOLING QUESTION
« on: May 9, 2017, 01:54:23 PM »
HI IM WONDERING IF I SHOULD RUN A RADIATOR FAN SHROUD ON MY 1984 DODGE RAMCHARGER TO KEEP THE MOTOR COOL. I LIKE TO KEEP THE TEMPS UNDER 200. I WILL BE PUTTING A HIGH FLOW THERMOSTAT IN THATS RATED AT 180 IS THIS A GOOD IDEA AS I DONT WANT TO COOK THIS MOTOR

    A radiator shroud is never a bad idea. Would help you out a good bit if you do a lot of stop and go traffic. I would be sure all of your other cooling components are sound as well, a high flow thermostat and fan shroud can only do so much if u got a weak water pump/clogged radiator/ ect.

    THANKS YES IM GOING TO FLUSH THE SYSTEM OUT IT USUALLY RUNS ABOUT 180 FOR THE MOST PART BUT SEEMS TO BUILD A LOT OF PRESSURE IN THE UPPER RADAIATOR HOSE AND PUSHES COOLANT TO THE OVERFLOW TANK AND TEMP LIKES TO CLIMB CLOSE TO 200 WHEN IM CLIMBING A GRADE ON THE ROADS HERE IN SOUTH EAST WISCONSIN

    Think of a fan shroud as more of an absolute necessity than a "pretty good idea".

    Also, your engine was designed to use a 195º t-stat, there is nothing to be gained by going lower.

    Reaching 200º (and then some) climbing a grade is perfectly normal.

    You're absolutely correct, Kendall. My mistake  ;D

     a junk yard who didn't scrap it all , or you can post here under wanted section ,of "classified " I'm sure a member has swapped a diesel or magnum and has a gas '84 shroud he'd ship to ya . and yeah the 180 is actually a bad idea .

    Thanks for all the help everyone I'm gonna hopefully finish the cooling system maintenance this week in between getting my crops in working my full time job and rains Sorry for the all caps the PC I was using always has caps on ill keep you updated also another question is does anyone have a wiring or plug picture for a wiper motor with delay as I'm going to bypass the main switch and use a toggle I want the high speed and low speed only. I know the motor works when I run it directly to the battery

    Like they said a shroud is definitely a good thing. Now since most t-stats are not precession instruments a 180 stat will normally run about 195 and is a good idea also 50/50 antifreeze is the best heat transfer even better than water also that piece of tin above the radiator that closes the gap between the grill and rad support needs to be there
    next a flex fan that fits in the shroud half way so that no more than half a blade shows outside and that is within 1/4 inch of the hole in the shroud is needed. Most of the stock fans and pieces are just about good for a stock unit any upgrades need help. wild red

    No good reason to run at 180, vs 195. Its like double the engine wear, and half the engine life.

    Based on the graph, I'd agree on the macro scale. On the micro scale, nah, I'd disagree. Operating an engine running 15 degrees cooler than 195*F isn't going to amount to double the wear or reduce the service life of the engine by half. The graph bears this out. In fact what we can see by the graph is, the amount of wear increases exponentially for every degree cooler the engine operates (hence the huge curve in the graph line)

    You can see that if you extrapolate a line across from .001 inch wear line. The amount of wear at 180 vs 195 is still well below .001 inch. The difference is negligible and far from "double the wear". What you gain here is an additional 15* of cooling capacity to work with.

    To the OP, thermostats aren't like on-off switches where the coolant begins to flow to the rad, the moment the thermostat reaches 180 degrees. It's more like a dimmer switch. As the temp begins to reach the preset temp range the thermostat  begins to open probably as early as 178* allowing some of the coolant to flow to the rad. At the preset temp, the max amount of coolant is (should be) flowing to the rad.

    200* while pulling a hill is well within normal and nothing to worry about. You should start getting concerned if the temp begins to exceed 220* -especially if you have an automatic transmission. At 220*, the ATF thats being cooled by your rad begins to degrade. At 230* the early stages of engine oil and ATF breakdown occurs, and early transmission failure increases. Higher than that and things can easily go boom!

    also 50/50 antifreeze is the best heat transfer even better than water

    Not that it is matters, but pure water actually transfers heat better than any mixture with antifreeze....but we certainly can't run pure water for corrosion, freezing and boiling point reasons. Basically, don't get any more concentrated than 50/50 unless you are in a really cold environment.

    You're referring to cavitation…it's more of a problem on engines with cylinder (wet) sleeves than bored engine blocks.

    Ok, I was thinking from another thread where they were talking about a 160 deg stat.

    The rating of the thermostat is the approximate temp that it begins to open, it will be fully open at 10 to 15 degs above that.

    A different thermostat will not give any additional cooling capacity. One could almost argue that a higher temp gives more capacity, as the difference in coolant temp, vs air temp, is greater, allowing for more heat transfer, but that is not "additional capacity", it is just more efficiency.

    That's why I run a separate trans cooler. In fact, I'm thinking of doubling up on the cooler.

    Around here... the thermostat opens and stays open. Even in the winter.
    When you live in a location like where you do, (The Semi- Great White North), for proper warm ups, 180- 190 should be fine.

    The rating of the thermostat is the approximate temp that it begins to open, it will be fully open at 10 to 15 digs above that.

    Wasn't it the other way around? Should be fully opened at rated temp, but starts to open about a few degrees below? Anyway…..

    What I mean by cooling capacity is, not that you'd make the system larger or more efficient, but rather an increase in the amount of 'leeway' or time the engine has before it can over heat. For example, if your engine tends to show signs of overheating at 220* but the engine is consistently operating at 200*, it doesn't take much to push the engine over the edge. Drop in a slightly cooler thermostat and you've increased the time before your engine overheats…..of course thats just the simple explanation and doesn't factor in all other contributors, buts that the theory and I'm sticking to it, unless your theory is better than mine  ;D

    I said earlier that the thermostat is like a dimmer switch…but perhaps a thermostat is more like a regulator, regulating the flow of coolant to the radiator. A 'stat with a lower rated temp will begin to regulate 'heat' a bit earlier allowing coolant to flow to the rad, at a lower temp to be cooled, but thats not to suggest that a lower temp thermostat will reduce the chances of overheating. It doesn't. It's just allows the coolant to start cooling earlier. But it also allows a little more time for the coolant to reach boiling point. But if you're consistently over heating, using a thermostat with a lower temp rating isn't a solution at all. Theres another problem that has to be fixed.

    Have you looked into Water Wetter? I seem to recall them stating that if cold temps are a non-issue, you can run water and Water Wetter only and this combination reduced operating temps better than any other combination of water and antifreeze, even better than a water, antifreeze and Water Wetter mix.

For example, if your engine tends to show signs of overheating at 220* but the engine is consistently operating at 200*, it doesn't take much to push the engine over the edge. Drop in a slightly cooler thermostat and you've increased the time before your engine overheats…..

    Yeah, that might postpone those higher temps for a good 15 minutes or so.  ;)

    Have you looked into Water Wetter? I seem to recall them stating that if cold temps are a non-issue, you can run water and Water Wetter only and this combination reduced operating temps better than any other combination of water and antifreeze, even better than a water, antifreeze and Water Wetter mix.

    You don't want to do water and water wetter only unless you have limited use like drag racing. there are several useful anticorrosion additives in the coolant not to mention boil over protection from the higher boiling point. I'd say no less than 30% glycol, water wetter, and distilled water. That is as good as it gets for daily use in hot weather areas. Realistically, 50/50 should be fine if you know what you're doing when you set up a cooling system. How do you think factory stock vehicles manage?

    Sure it could postpone those higher temps for 15 minutes or so, depending on the efficiency of your cooling system and numerous other factors, and it could also give you a cushion that might not exist otherwise.

    I think we'll just have to disagree on that point, because the only possible "cushion" it could provide is possibly a bit of added time from cold start up to the operating temp.

    If the current load on the engine and the cooling system efficiency can only maintain 210º (for example) it doesn't matter if you have a 160, 180 or 195º stat in....they're all wide open and having no influence on the system temp.

I know the motor works when I run it directly to the battery

    no influence on system MAX temp , but plenty on the Min temp .

    Also, your engine was designed to use a 195º t-stat, there is nothing to be gained by going lower.

    I must disagree with you. I live in Florida with the A/C running in normal traffic my temp would get very high. I put in a 160° thermostat and no longer do i get near the temp level i used to get, topping out at the halfway hash mark rather than almost the letter H.
    Prior to that i had replaced the radiator, the waterpump plus most of the underhood A/C parts.
    Now i can enjoy my A/C while driving in traffic and not worry

    I'll add to KThaxton's comment:  "Your engine was designed to use a 195º t-stat.  With a properly functioning cooling system, there is nothing to be gained by going lower."

    If you find you get better cooling by lowering the temperature of the thermostat, something is wrong.  Our engines are designed to operate at a specific temperature to operate like they were intended.  On some engines, like fuel injected engines, using a lower temp thermostat will keep the engine in "warm up mode" constantly which will cause it to run too rich killing MPG and potentially causing other issues like fouled plugs, which carb engine can also suffer from due to lower operating temps.  If you are having overheating issues, fix it correctly and don't waste time with band-aid fixes that cause more problems then they solve.

    With our next-to-useless temp gauges, that doesn't tell us much. That could only be a difference of 5-10º. We don't even have a clue as to what hitting the "letter H" means, and it varies with each truck! It could be 205º near the "H"...which is within the "ideal" range.

    To demonstrate the inaccuracies of the stock gauges, on mine (I had an aftermarket gauge and the factory gauge). Normal operating temps of 195-ish, my stock gauge was one notch next to "C". If it got to around 210-215, it was almost pegged. This is not useful information.

    What I stated earlier is a basic fact......if a cooling system could not maintain the desired 195º range (and it IS desirable to run near 195 as Elwenil and others stated), it certainly could not maintain 160, or 180 or whatever...simply because that rated t-stat was installed.....and with the negatives of running at lower temps....why would you? There is nothing to be gained.

     all that tells me is your original thermostat was bad , new or otherwise.. all a stat does is close the flow when the motor is cold , ounce the motor reaches the stats temp , it opens , your truck should use a 195 stat . the stat is the low limit flow switch , the rest of the cooling system , in conjunction with ambient air temp , is the high limit .   but believe what you will  ;D

    We can disagree simply because we are disagreeable people, but as I said before there are numerous other factors involved.…..

    If we were to assume one type of constant use, but engines aren't always at WOT, or running at highway speeds all of the time. I'll give you an example. Say you're in stop and go traffic on a nice spring day, thats not too hot or too cold. Or you park with the engine running. It's quite possible that the rad can cool the coolant to below the stat's temp. If that coolant can circulate up to the head, and still be somewhat below the stat's temp, the thermostat will close a little (the regulate part I mentioned)

    Engine temps vary thru use, some more than others. But we will continue to disagree

    I've found over the years , its takes quite a bit more than a cool spring day to get a gasoline engine cooled enough for the stat to begin to close , and air flow thru the system would even help . A windy winters day of 15 below , parked overlooking the Atlantic ocean , for example , does cause it enough to even lower the heaters out put , and make you "move on" . A 25'F below 0 day here and you'll wish you had a 196 stat in it , AND a "winter front" covering the entire grill .  Folks in warmer climates , fla , calif , etc may never see any of that . The stated purpose of the stat is to bring the engine up to operating temp quickly ,however , under extreme conditions it may "regulate" to some degree .

A 25'F below 0 day here and you'll wish you had a 196 stat in it , AND a "winter front" covering the entire grill .  Folks in warmer climates , fla , calif , etc may never see any of that . The stated purpose of the stat is to bring the engine up to operating temp quickly ,however , under extreme conditions it may "regulate" to some degree .

    I heard "stories" about that product.
    I'd like to investigate that stuff to get the scoop on it.
