Overheating due to radiator stop leak. Sign In

hello, i have a 1986 nissan maxima (3.0 v6) with 96k miles. this past september, i used stop leak in an attempt to fix a leaky heater core. after using it, it gummed up the cooling system causing the temp gage to go past the normal operating temp. i had it flushed a month ago and replaced the thermostat yesterday. while replacing the thermostat, i noticed that there was still a thin coating of stop leak inside the hoses and the radiator. the temp gage still goes past the center mark (which it never did prior to stop leak) i am planning on completely fixing the problem by having the system pressure flushed again and replacing the radiator which is original to the car. I am just looking for some suggestions on what to do to completely solve the problem.
By the way, the car does not leak coolant, and the heater core is bypassed.
Thanks!

You're on the right track with what you are doing. About the only other thing that may still have a problem is the heater core. It will get clogged just like the radiator and it already has leak issues.

NEVER do that again. There is no such thing as "Mechanic in a Can".
