During the summer months I have been having an over heating problem. On friday I changed my radiator, upper and lower hoses and heater hoses,replaced the t-stat with a Mr Gasket 180 and replaced the coolant. The overheating problem is now gone. On the street the car drives normal with the gauge between the N and O position. And when I go up hills, or get on the gas hard, it hits the R mark but than will cool down. However when I'm on the freeway the gauge will drop down below the N position. ,Does anyone else's car do this. I had an other 94 and it never did that. Should I put the 195 t stat back in? Im gonna get a gauge and see what the actual temp is. I just need to know if its normal. If it helps, My mods are Frpp cobra intake, bbk cai and flowmaster catback. Thanks in advance.
