over heating any ideas?

[axmarque]

well since the past week the temp rises up when im at a red light for a couple minutes and as soon as i start moving again the temp lowers back down to normal temp, my guess that it may be my water pump if you have any ideas let me know thanks

Check your fan fuse

im sure that the fan works

It may "work" but sounds like your fan is not kicking on. you can jump the wires at the fan switch by the thermostat to see if your fans turn on. If they do, it might be the switch that's bad, if they don't it could be a fuse or bad fan motor.

I had problems with my fans not kicking on after I put in the new radiator. Turns out the new radiator is just that much more effecient that they hardly ever run at all.

How are you sure? Your symptoms say fan. The water pump being out would overheat moving as well as sitting. No airflow across the radiator means overheating at rest, but not in motion. No waterpump means overheating, period.

both you guys make sense. the reason i thought it was not the fans was because when it started over heating i opened my hood up and both my fans were on

not necessarily, a stuck shut thermostat can cause the same affects. , but it would overheat while driving as well and get higher in temp when parked.

i'd say if your fan is working, then it would be the thermostat, if the fan isn't working, get that fixed and then see if your overheating continues, if it does, replace the thermostat, if you still overheats, and would be unlikely if it hasn't been changed in forever, then it would be the water pump.

good luck

i thought fans at first also, but since you said they were both on, i'd then suspect the T-stat also. water pumps are very rare to go bad. later.

My bad, I forgot to mention a stuck t-stat. I haven't had one in my coupe since I got it, and was just complaining about the lack of heat when the car is rolling and it's cold as shit outside, so I should have thought about that as well.

Since both fans were visibly running, Ox has probably pinned it down.

When water pumps go bad, they LEAK. As long as it's turning, it's pumping water. Unless it's an MGB which had a stupid plastic impeller that would melt.

you should also bleed the radiator because the coolant lines might have air inside them and that will cause the engine to overheat. if that doesnt work you should check your temperature sensor. see if that will solve your problem.

Yeah all that. And go head and change your thermo while you at it cuz that shit is easy as hell.

thanks for the help all very good ideas.

Have you checked the coolant level? low coolant will cause the same problem. I've had that issue, just yesterday as a matter of fact
