hi , i have recently bought a prelude 93 and it's overheating badly.
The bottom hose is staying cold, i changed my thermostat, water pump, sending unit, rad cap, head gasket (tested) and rad seems ok. Now i really don't know if my thermostat is ok because some people are telling my they got pin into and i don't have that. I have a 64mm opening at 180f (we got winters here) And also there is no pression in the cooling i can open the rad cap when it's hot! No pression.

Also if it can help you figured out i did a small hole in my last thermostat and he was less overheating (with the heather on).

Thanks
