I have recently bought a 1997 2g GST Spyder. I swapped over the cooling system from my old car as it ran 195-203 on that car all day long in 100deg Texas heat with FMIC and A/C.
My spyder though, it just seems to want to run hot. I know its an airflow issue because it runs hotter going down the road and if I get over 75 it will just overheat to where the CEL comes on. When I am driving in stop and go traffic in the same heat it will sit around 212 (which is perfectly fine if a touch high). This is through ECM Link as well as verified with my aftermarket water temp gauge.
I currently have:
- 68HTA with stock heat shielding
- Coated manifold with blanket
- Coated 02 housing and coated downpipe (again with stock heat shielding)
- ETS Street FMIC
- Completely sealed ducting from FMIC to condenser
- Completely sealed FMIC to Radiator
- Completely sealed stock fans to radiator
- Stock (and brand new) thermostat
- One bottle of Water Wetter with ~20% antifreeze and distilled water
I also still have:
- Stock P/S cooling line
- Stock auto Transmission cooling
I'm not really sure the route to go here anymore because everything I read says, "if you do the above you won't overheat", but here I still am. I also know this is a proven setup as I have run it myself with no issues before. I bought this car to drive and any that has seen it can attest that it is one of the cleanest DSM's still on the street. As such I would really not like to put more holes in the front bumper. I would also like to keep the stock fog lights. I guess my options are
1. bigger radiator (Mishimoto X-Line) - but not sure this will cure my problem
2. lower thermostat - but again this won't really fix my problem
3. Venting the hood - not going to happen with the stock hood
4. buying a vented carbon fiber hood. I hate that look and I hate hood pins but I don't see much other option than this one.
5. Maybe an oil to air cooler would help? This one I am not sure on. My old car had one, but it leaked constantly and I hated the damn thing. maybe going with a different kit would be a better choice.
If anybody can offer any advice I would be appreciative.
