Ive noticed for the past few weeks my 90 ex started getting hot while I was sitting at Idle at a drivethru or waiting in a parking lot.
Now it does it while I'm cruising at 55 but it will go down if I rev the engine.

Could it be the water pump going out?
If so cool it will give me an excuse to pull the engine and change all the leaky engine seals

I replaced the thermostat about 8 months ago.And the ac fan is new just changed it a little over a week ago.

 

any pressure in the radiator on start up?..are the cooling fans coming on and cycling? Any white smoke from the exhaust?

 

It's not smoking and the fans work good.I'm not sure if the radiator is pressurised on start up though.
I'll check and post it up.

 

change your t-stat out

 

Well I was sitting in a parkinglot waiting to pick up a friends kid from school and I heard a loud pop and some smoke started coming from the front of the car.

I poped the hood and checked it out there was some antifreeze sitting ontop the radiator and on the bottom of the hood.But nothing was leaking.

The car wasn't hot so I turned it back on and we drove it like two miles home.I lett it sit and idle for like five minutes then coolant started pouring out of the radiator.

Could it have been a bad thermostat causing pressure to build up and blow a hole in the radiator or something else?

 

I wish I would have changed that t stat when you told me Yue.
I just don't drive that car everyday so it kind of slipped my mind.

No, the Radiator cap is calibrated to pop off like a horny sailor at 18psi. I believe you were dealing with a fail(ing) radiator that had developed a slow leak on the side facing forward (towards the Condenser), where it can't be easily seen.
If it were relatively high on the radiator, it may have been loosing coolant in the form of steam; making it even harder to spot.
That's why your temp was slowly rising, you were slowly loosing coolant.
When you replace the radiator, put a fresh cap on it (and replace the t'stat as well).

Thanks P.Actually thats exactly where the leak is.

 

That tune-up I gave the ol' Crystal Ball seems to have worked out.

Glad I could put a face to the problem
