My oil temps run a constant 130+/- regardless of outside temps or how hard I'm getting into it. Coolant temps run about 180 unless its hot out, then it will run up to 240-245 in traffic. Shouldn't my oil temps be running hotter than that?

Is your gauge accurate?

I've thought about that. Much has been said about the inaccuracies of the analog guages. I don't have the needed equipment to check the temp though.

You need a scanner sooner or later so only thing left is an IR thermometer. Read what the ECM is seeing and confirm it by hitting the sensor with the thermometer.

That is not true at all. Sorry, but it's an erroneous conclusion drawn from a different situation than we have. Read THIS. Pay special attention to the last two paragraphs.

With no stat, the car will run as cool as the capacity of the system will allow. Most of the time it'll run much cooler, but in HOT ambient temps under a higher load, it'll end up ~200 or so with or without a stat. It could help....but it's not the right way to manage your operating temps.

I agree with the poster who recommended cleaning the radiator. I'd also flush the cooling system and it should then run "down against the 'stat" about any time you're underway and have air flow.

To keep it simple & answer the original question:

1. Lower temp thermostat
2. Fan on/off temp lowering
3. Oil cooler

This is all assuming you’re running the right viscosity oil, cooling system serviced/good working condition, radiator area is clean of debris and obstructions. I have items 1 & 2 done.

Whether or not that temp your running at is normal, well that’s a separate discussion but many wouldn’t have issue with it.

First - Check the oil and coolant sensors as one of them could be bad Something doesn't sound right as your oil wont generally run 50 degrees warmer than your coolant.

Second - Do not put a 160 stat in your car. Not to start a thermostat war but your car was DESIGNED to run a specific temperatures. Most of the overheating is just a mental concern for most people. Look at the service manual and if you fall within normal driving conditions then it's not a problem that needs to be fixed. Also, to cool of a system is not always better especially if the car is not tuned to take advantage of that additional cooling. A car that runs 215 degrees with a 195 stat will not run cooler with a 160 degree thermostat. It will just delay the time it takes for the car to hit 200 degrees as both thermostats will be fully open at that point anyway. Above about 40-50 MPH the stock fan actually becomes a restriction to airflow so if you are running hot while moving it's not an airflow problem but the cooling system (poor flow, blocked radiator, etc). If your cooling problem is below 40-50 MPG and not above it's an airflow issue (fan).


For your specific issue, I think you more than likely have a sensor calibration related error.

Sulfur melts at 239.4 and boils at 832.3 (Fahrenheit) so somewhere in between?
