Ok, I've been unable to find anything specific about my scenario by searching, and I have a feeling I might know the main cause I just want to get some insight.
92 awd laser, Mods are ETS fmic (I think this is the main problem). 16g, 3" exhaust, all heat shields installed, only one fan but it seems to work right.
The car can sit and idle or be at 2-3k rpm and not have any problem even with the hood shut. As soon as I drive it about a mile it will start to creep up in temperature it will get hot enough eventually to start boiling out the overflow.
There are no "bubbles" when the rad cap is off and its running, I've done a hydrocarbon test on the radiator "air" and it turned up with no hydrocarbons meaning a good headgasket, the compression is fine also.
I've taken the thermostat out and it helps just a tiny bit (maybe). I've flushed and added chemical flush to the coolant and I've tried 100% water which I heard actually cools better then antifreeze?
I guess I'm wondering is the ETS kit blocking out all the air that the radiator needs? The 92 front bumper design basically allows for no airflow other then to the fmic.
I'm going to try replacing the radiator with another one I have that was from a ok running car. Oh, and I've tested the heater core and it seems to flow quite well.
Let me know what you think it might be??
Thanks,
