Overheating

[Murfman]

I noticed my temp got way up while sitting at the bank the other day. It didn't overheat but it was up between the top normal line and the H. I shut it down till I was done and then when I left, I turned the heater on to aid in cooling. The rest of the trip home it was in the normal range. When I got home, I let it run and after about 45 mins, was up there again. I checked the fans, they are both running. All my trips to/from work and around town it is fine. I am kinda hesitant to take it out on a long run but need to resolve this as I am driving it back east this summer.

Any Ideas?

clogged radiator. when the engine speed is up and there is air moving across the rad it can keep it cool, but when you stop the water flow slows down and there is no air across the rad to aid in cooling. either that or water pump, but more likely radiator or heater core. you can take off the top and bottom radiator tube, and pour water into the rad and see how fast it comes out the bottom. it should flow out as fast as you can pour it in.

Heater is working fine though.

my heater in my honda worked fine when the radiator clogged, and helped it keep cool for a while, but eventually the clog got so bad nothing worked and then it would overheat just by running for 5 minutes.

I'd try to clean out the radiator with a garden hose. I think the fins may be clogged.

Also, did you have the A/C on at all? The defrost will kick on the A/C, and the computer won't kick the A/C back off until the vehicle is shut off, no matter what position it's run on.

What do you mean by 'both fans' are working? You also have the electric fan in the front of the A/C condensor? The other fan is presumably the clutch fan?

you may try a thermostat it might be sticking closed check the lower hose if it is not as hot as the top hose that may be your problem Tstats are cheap and a good place to start before spending the $$$ on a radiator.

I would start will what Allen suggested. Take off the nuts on top of the radiator so that you can lean it back towards the fan, rinse between it and the AC condenser. This has solved the problem for a number of people. It didn't help my overheating issues that started last summer. This fall I replaced the radiator with a radiatorbarn.com one, and the thermostat, but it hasn't been warm enough since then to know if I actually solved my problem. I'll find out at GONE!

Thermostats are cheap. Change it. I had a leaky radiator once but every other time it was just a bad thermostat.

The radiator barn is ok check out radiators 911 free shipping and they sell performance you may also check around town.

Yes, I have both fans.
