Normal Engine Temperature?

[WP935]

My '70T - 2.5 (66x90) with a cooler in the nose, on the track would run @ 180 consistently, maybe a bit higher on a real hot day.
If I was really climbing on it, pushing it hard, maybe 220. @ 220 I paid close attention and backed out of it a bit.

smiles11 - couple of questions-

- what weight oil are you running?
- does your car have an external oil cooler?

20W50 & yes to front cooler

I don't know what your front cooler install is, but I have seen people just hang a cooler in the fender and call it done. Unfortunately it doesn't work that way. The factory set up has a plate that forces all the air thru the cooler, it can't go around it. Secondly that louvered plate creates a low pressure zone due to air direction from tire rotation, that helps draw air thru the cooler in addition to air force fed from car's forward motion. Generally factory set ups seem to run about 190 to 220 given most circumstances.

Here is my front cooler.

Sorry they’re upside down

Sorry they’re upside down

Got'cha covered smiles...

This is far from the factory setup that Ed was referring to...


The factory setup looks like the this .... the cooler is in back of the right headlight bucket, and the cooler itself is in front of the louvered shield...

Hope this helps,

That's an AC condenser, not an oil cooler.

Thanks guys. That makes more sense. The car had factory A/C, but was removed when the engine was rebuilt. Explains why my temps climbed during traffic & steep grades.

I might have to look into getting a front cooler added. Is that a simple modification I can have done at an independent?

Here is a factory style oil cooling loop.

Yes, it can be done. You will need the External Thermostat, the lines to the front, and a trombone or carrera cooler in the fender well. You will also need to replace several lines between the engine and the oil tank. To get maximum cooling, use the factory hard lines or the finned elephant lines.

Then there is, drive from Denver through Nevada to Palm Springs in 115 degree heat for many hours at 80 to 100 mph. Two triple loop trombones and 14 quarts kept the oil out of the engine a few seconds longer and kept the temp at 190. Overkill maybe? Peace of mind for sure.
