Keeps on overheating

I got my water pump replaced as well as timing belt and gaskets. My problem was that my water pump was bad because it was leaking coolant through the weep hole. Yesterday i go out an get new tires, inspection sticker and everything ok. I would see that the temperature wouldn't go pass half. Today i drive it for 5 min and its overheating. I took of the thermostat to see if that was causing this and no, it still over heats but take about 15 min before the temperature passes half. I got no coolant leaks through any water hose, but Ive seen some on the ride top side of the radiator Could this be the problem or maybe the water pump that i bought is broken?. Any other vehicle in which i could get a radiator from ? any interchangeable car? Ive seen a few 5th gen radiators on the junk yards but ive read they dont fit.

Re: Keeps on overheating

If you're seeing coolant near the top of the radiator, it's possible the rad itself has gone bad. It's pretty common for them to eventually leak where the plastic header meets the metal core, or to develop cracks near the top inlet, where the upper radiator hose attaches. Forget used radiators -- you can get a decent radiator online for under $150 shipped, and it's not that hard to install.

Re: Keeps on overheating

Have you checked that your fan(s) operate?
Agreed another radiator is likely in order, unless it's clogged that little leak isn't causing your car to overheat.

Start the car with the a/c and climate control on and confirm that at least the condensor fan runs.

Re: Keeps on overheating

I dont think its my headgasket, it was also replaced. As for the fan, it is working it is turning on. What else could be bad, I dont have any leaks the water pump was replaced, I bleed the coolant the only thing im left with is the radiator which once got clogged and caused my car to overheat. How can i check to se if its clogged ?

Re: Keeps on overheating

Both hoses should have pressure when the t-stat is open. In other words all is flowing throughout. There is a 5/8" t-stat bypass on my B21 that lets some water flow until the thermostat opens. One pita but sure fire way to check flow is to remove your bottom hose, (drain the radiator first) and fill it with water. If it falls out lickety split, you have flow. I mean like flows out nearly as fast as you pour it in type thing.

In my other vehicles of the past when the thermostat sticks closed there was no warm air from the heater. And I've bought t-stats that were no bueno.

Oh, try replacing your radiator cap. Sometimes they stick closed and (don't ask me how) can cause overheating.

Re: Keeps on overheating

Thanks ill try that today. Ive been reading about this and saw about what you just told me. Thermostat is not the problem cause it keeps on overheating, the only things left are the radiator itself and the cap.

It depends. Certainly not due to coolant loss, but if the radiator's not holding pressure, the coolant boils at a much lower temperature, just like it would with a bad cap.

And Roni...know that we're all just pitching out ideas. Fixing a car you can't see or touch is notoriously difficult. Just ask the guys who do Car Talk. :)

Re: Keeps on overheating

Oh, so if the cap sticks open, that's when the overheat dilema arises?
I'd presumed it was when it sticks closed...

I swear this is like the 743rd of your posts of learned from.

Re: Keeps on overheating

Blown head gaskets are far less common than message board discussion makes them out to be. Driving around on an engine that's overheated risks blowing the head gasket or warping the head, but it's usually not the first cause of overheating. I've blown a head (not on the Prelude), and there's no mistaking it for anything else, either sight or smell! Plus, the car often won't start afterwards.

Re: Keeps on overheating

Ok, i bought the radiator tried the car and it did not over heat while i drove it for 30 min (no thermostat). I go today and buy thermostat and coolant did the bleeding process and the thermostat would open because the lower hose was cold and the top was very hot. I realized that the the part circled in red is clogged. Could this cause the car to overheat with the thermostat. Is there a way to remove it from the throttle body and remove all the rust? i tried poking with things to try for coolant to circulate but it clogged inside.

Re: Keeps on overheating

I believe what you've circled is the connection to the fast idle control valve. If that's clogged, the worst that should happen is your engine doesn't come off of fast idle (the system thinks the engine is still cold) or the idle speed hunts back and forth.

Also, which part is clogged -- you've circled the connection on the thermostat housing and the connection on the throttle body?

Re: Keeps on overheating

the part that is clogged is on the throttle body. I again took the new thermostat off the car and no overheating, but what im concerned about is that the car will always be running on hot coolant, what is the worst that could happen. I have no more ideas what could be causing it to overheat. new radiator, thermostat, fan is working. new water pump, its just that the thermostat is not opening in order to let cool coolant into the block.

Re: Keeps on overheating

Certainly replace the thermostat -- that can make a difference!

After looking at it again, the clogged tube carries coolant to heat the lower portion of the throttle valve. I'm not sure why, unless it's to prevent the inside of the throttle body from icing at part throttle (similar to carburetor heat in aircraft engines), but it has nothing to do with whether you're overheating.
