These are all good ideas but I’m not sure what some of them have to do with overheating. The car doesn’t overheat all winter so I’m thinking it’s not engine damage or cats. It just can’t dissipate enough heat. During the winter the radiator did not need as much airflow through the radiator because the air was much cooler. You don’t need as much air if it’s cold. You need a lot more air to cool if it’s warmer air.I Agree. In such a hot climate you should not run that low of a thermostat, the airflow and the efficiency of the radiator cooling will be none existent.
- Verify Cats are not clogged restricting flow, either remove (Best for Engine) or get a set of high flow cats which will flow enough for the FI boost you are using.
- Send your data log to a good tuner like Wengerd and see if they can see an issue which could cause overheating.
- Make sure all of the radiator shrouds, air deflectors, covers ETC are installed.
- Manually connect your radiator fans to an on-Off switch inside so you can turn them On-Off when racing or necessary.
- Make sure your AC is turning off under full throttle.
- Do a Pressure/drop down on your Coolant system to ensure their are no leaks (remove thermostat during test).
- Do a Cylinder Pressure Leak Down check not a Compression check, to see if all cylinders are within specs from each other.
- Bore scope your cylinders/Pistons and check for hot spots, uneven burning ETC.
- Make sure your hood vents are working and actually removing the engine compartment heat not trapping it.
- ** Mount a Digital Wifi Thermostat in your engine compartment and data log the engine bay temperatures during cruising and Hard pulls see if you see an issue.
I would like him to add a way to measure the airflow through the radiator if possible
