98 Pathfinder overheating

[swag]

A couple of months ago I was driving down the highway at about 75mph and I lost driving power to my Pathfinder. I got to the shoulder of the road and when I got under 50mph my gas pedal came back and let me drive to the next exit. A govenor kicked in to keep me under 50mph.

When I got off the highway the computer was read and it was the knock sensor. The mechanic told me the computer kicked a govenor on while I was driving. When I got off the highway the engine overheated a little. The coolant was replaced but ever since then I have been having problems with the car overheating.

When I drive the car usually stays right about 50% temp. After sitting in traffic or driving for a while the temp will shoot all the way up. I have to turn the heat on full blast to get it to stop and come back down. The heater almost always works.

I had the fan clutch replaced because I was told it went bad. No difference. Does anyone have any ideas???? It is driving me crazy and I am worried I am doing damage every time it heats up.

Thanks,Swag

change your thermostat.... thats step one! then replace your radiator if that doesnt fix it.

YES, CHANGE YOU THERMOSTAT! Mine did the exact same thing and then overheated and blew the water pump 3 days later. Please don't wait like I did!
