Whats Your Temps These Days

[55 Fargo]

Hi all, been driving the 47 the past few days. The outside ambient temps are low 80s, high humidity.

I find my engine runs around 175 f, on the highway at faster speeds, and while travelling with the wind, it will climb to 185 f, this usually comes down as I begin to drive slower in town, or if I drive against the wind.

No big deal here, I am content with these temps, I do think however, my engine temps would hit 200 on super hot/humid days at higher highway speeds, where the engine needs to work harder.

I am still running a 160 t/stat, this means nothing as it will be fully opened after about 170 degrees, then the engine will run her temp.

I am using a 47 Dodge honeycomb rad, it's very clean, and flows well, but is old, so it's heat dissipation capabilities, may not be what thtey once were.

So what about you guys, what engine temps are you running in summer?..........Fred

rock, my 265 will run up to the high end of the normal range on my temp guage, which is probably around 190. i have installed a 6 volt fan on the front of the re-cored radiator, so when i sit in traffic i turn that on. it has never overheated but without the fan it more than likely would. we get 95 degree plus days here in north carolina.i also use water wetter in the cooling system and it does help. my system is all new except i need to pull the freeze plugs and clean out as much as possible as that is the only thing left that keeps my engine running hotter than it should. dennis

When I went to the bank yesterday the outside temp was 102F, The engine temp in the 48 did not go over 180. I am running a stock rad with a 180 t/stat. I run a 50/50 antifreeze mix with 1 bottle of Water Wetter.

Dennis that soundfs very good, I wonder if your very dry heat, will allow the rad to to dissipate heate better than when it is very humid.

A lot depends on many variables, speed, wind direction, hills, etc.

It's about 85 and very muggy here right now, just was taking out a dash in a very dirty parts car, and have pulled a least 10 ticks off me, I was sweatin in the parts car, ticks are late this year.....

MIne runs between 160 and 180, only time it went above 180 was sitting at customs coming back from detroit last year. Sat for about 40 minutes in 80+ temps. went to about 200 a couple times, had to rev it in neutral to cool it down. Guess we got in the line for officer thourough as the other liens were twice as long and moved twice as fast.

I did notice that it had creeped up to 190 after about 15 miles onthe interstate the other day, when I checkked the level was down, put about a 1/2 gallon of water with about a quart of a/f in and it borught it back up above the core. Temp has been back to normal since then.

I run about 70% water to 30 % coolant.

My recollection on this is very hazy, but I think that it is the reverse and that humid air should cool the radiator better. Humid air is not as good on people as we perspire to keep cool and that is less effective in humid air. But our cars should not be perspiring.

In its current state of repair (replaced the radiator core about 10 years ago) and a 160 degree thermostat my 1933 runs around 150 degrees most times. I did once see it go to 180 when climbing a long relatively steep grade at 50 MPH while fully loaded (full throttle needed to maintain speed) and the ambient temperature was around 100 degrees. And my dash gauge has been calibrated to read 212 degrees when the bulb was immersed in boiling water so I am pretty sure the engine temperatures are what the dash gauge says.

Mine runs at about 180 to 190 while driving. Will creep up if sitting & idling

in pretty hot weather.

The 40 Plymouth runs at 170 most all the time. I dd a parade last year and saw it at 200. As soon as I got on the highway it went back to 170. I think last week I had it out na dsaw the temp get to 210 I stopped and opened the hood to check the level(antifreeze) and I could not see any in there. I stopped and got some water and temp went down quick. I think I put to much antofreeze in my cars. I need to do the 50/50 mix:)

Hi Tod, thanx for the correction on the humidity factor, always thought it would be more difficult to cool in more humid conditions.

You run a 160 in the 33, and it runs 150, that t/stat must be closed or only partially opened all the time, is your rad that efficient, it certainly keeps the engine cool.

I have read, a 160 t/stat will begin to open at 153 to 157, and be fully open at 180. I klnow mine will run at 155 or so when the weather is below freezing, because of the 160 stat, but keeping it running at 150, during warm to hot weather, mine would never stay that cool..............Thanx Fred

PS do you still repair/splice in new temp sensors to OEM gauges, would like to try this but am afraid to screw it up.....

I've done it on my own car and have helped a couple of other local people out with theirs. Last one was about 5 years ago. But if someone local wanted to that tomorrow it would not be a big deal for me to help them out on it.

Man, Dennis, is it already in the 100's up there? We still have it in the high 80's down the hill here, but can feel the humidity.

My temp is staying between 160-180...mainly 165, so far. That's a lot better than it was two summers ago.

It was only 105 today but they say that it's going to get warm next weekend, they say it's going to be from 110 to 115.

What has changed with your car since two summers ago to get it to run cooler?

Thanks.

I would prefer to have my engine run at 175 to 185, I think 160 is too cool.

The 160 t/stat may have been meant for the use of alcohol antifreezes, and for cooler weather temps, but for ethylene glycol based antifreeze, a 180 t/stat may be the way to go.

Having said that, I am running a 160 t/stat, a 180 t/stat will just take a bit longer to fully open on hot days, but also once open she is wide open, but once the engine warms up on hot days, the t/stat will open and the rest is the cooling systems efficiency.

Running from 190 to 200 is not my idea of fun either, although under 195 should be no problem.........Fred

The water tube and freeze plugs shoud be pulled, and then rod out as much crud as possible, run a pressure hose into evry opening, flush out as much as you can....
