Think I need an external oil cooler..., who makes the best kit? Options

[ClayPerrine]

I normally set up an external cooler so the fan turns on a 190.

Standard thermoswitches for coolers kick on at 180*.

Newbie here so go easy. I have had my '75 2.0 liter for 6 months. It was over 80 today in the bay and coming home at 85-90 up the 280, the cylinder head temp went up higher than I've seen it before - maybe a quarter inch off the red portion.

Does anyone have a correlation between the dash gauge and the actual temperature of the heads and the oil - and what' too hot?

There was no effect on how the car ran...and it cooled down to bang in the middle of the gauge once I was back in foggy San Fran...

That's oil temp, not head temp.

The exact temps represented by the different areas on the gauge can vary from car to car. You can calibrate yours with a thermometer down the dipstick (several retailers sell these) or by removing the sender and setting it up in a pan of boiling water or in a pan of hot oil with a fry thermometer.

I didn't see any mention of the type of front spoiler/air dam you might be running.

The flex dam causes cars to overheat without a front mounted oil cooler.

Also, are the air diffusers still in place on the under side of the car right in front of the engine compartment?


My motor runs at 180-190° on the track when it's a 111° day.

I run a large front mounted Setrab oil cooler, Mocal thermostat and a large inlet/exit with a shroud in the front trunk.

flex dam, is that a front air dam? how do you reckon it causes high temps? I'd be thinking it would help reduce the air pressure under the car and thus aid in engine cooling air flow. That is just my assumption, how do you figure it causes higher temps? I must not be thinking about it right.

If you run at 180 you never get all of the moisture out of the oil and it begins to make that nasty butter. I am in the 212 camp, too.

if your oil sump (typical location for a temp measurement) is at 180F I can assure you that some of the oil some of the time exceeds 212F. if yoru sump is at 212F I can asssure your some of your oil some of the time exceeds 244F.

think about the oil in the heads, one of the hotter parts of the motor, oil that flows thru there is in direct contact with 300F+ metal. if you feel you need 212F oil to remove water, I can assure you that a 180F sump temp will meet your boiling point temperature needs.
