i have a 92 si with a 95 gsr swap...my coolant temp gauge says im running at 210 to 250...i have an aftermarket radiator and it is full...i was wondering if anyone could help me figure out why its overheating??

 

Did you bleed the system after you did the radiator swap?

 

Is your coolant bled? Does your fan come on? How old is the T-stat?

 

im not sure if the radiator has been bled it came with the engine swap...my fan does come on...and im not sure how old the t-stat is...is there any way besides using a temp gun to see if my temp gauge is working or not?...cause i dont think its right

 

replace the thermostat and then bleed the coolant.

 

could be a water pump

 

ok ill try replacing the tstat...but how do you bleed the coolant?
