0 B C Posted March 22, 2013 Report Share Posted March 22, 2013 It definitely sounds fan related but if you are confident that the fan is working...... Ensure you are running proper coolant (50/50 mix). Bleed the cooling system, spray your radiator and AC condenser to clean out bugs and dirt that may be blocking the passages, run Redline Water-Wetter, check water pump belt tension, consider replacing water pump and thermostat if you are uncertain of when it was last done.

0 Earl Posted March 22, 2013 Report Share Posted March 22, 2013 My thermostat has been bad and it does the same thing. It starts to get warmer when sitting, but not always. It could be a bad waterpump too? I know they came with a plastic impeller stock. That could have broken, leaving it to move water slower while at idle, versus under a load. Just a thought Quote Link to comment Share on other sites More sharing options...
0 Guest Mott Power Posted March 22, 2013 Report Share Posted March 22, 2013 Check the thermostat, mine recently went out and would fluctuate oddly like that as well. Quote Link to comment Share on other sites More sharing options...
0 240sxguy Posted March 22, 2013 Report Share Posted March 22, 2013 My 530 did that when the thermostat was acting up too. Fix it now, and don't sit and idle it if you know there is a problem unless you want to put a new motor in there. Quote Link to comment Share on other sites More sharing options...
0 e36mpwr Posted April 6, 2013 Report Share Posted April 6, 2013 Check the fan clutch same thing happened to me. Keep the car off and open the hood and spin the fan if it's loose the fan clutch is out. Quote Link to comment Share on other sites More sharing options...
0 Jeff Posted April 6, 2013 Report Share Posted April 6, 2013 If your fan is working properly and make sure it is not loose and it has some tention to it when you spin it. Check that your coolant is topped off best time to do it is before you start the car in the morning when it has sat for a while. If your coolant is full then change your thermostat. It sounds to me more like a thermostat or low coolant. Seeing as when you sit it gets hot and when you move it is normal. Quote Link to comment Share on other sites More sharing options...
