I have a 96gsr 4dr with 309k. Lately I have been having problems with my cooling system.The reservoir keeps filling with coolant and does not return to the radiator. I have replaced the thermostat and radiator cap with oem parts, the upper hose and have flushed the coolant 2x. There is no oil in my fluid and I am not overheating. I also have no leaks. What could be the problem? Is it my radiator?

 

Is your water pump circulating the coolant..?

 

How can you tell? I took the rad cap made sure most of air was out.

have you ever had the water pump changed? i would check the water pump if you havent changed it at all? its definately time @ 309k.

 

309k miles

 

I changed the water pump last year with the timing belt. Do you think that i have a slow leak on my head gasket?
