2000 Ford Mustang Q&A

2000 Ford Mustang Question: Turned heat on, blew cold air, looked at temp and it was red line.

Engine started making noises like a large ball bearing in a tin can, I stopped. Steam pouring out the passenger side of the car (outside), opened hood, radiator was 1/2 cup low, reserve 1/2 full. Little bubbles were fizzing where the intake manifold meets the engine block. Once it had cooled, it did not make any noise and ran fine. A mile up the road, the temp was almost to red line again. No water spray on the engine, oil is clear. The radiator has never been flushed that I know of....where do I start? Has never done this or anything else before. -
Answer 1
POSSSIBLE STUCK CLOSED THEMOSTAT WHICH IS BUILDING PRESSURE IN ENGINE CAUSING INTAKE MANIFOLD TO LEAK UNDER EXTREME PRESSURE. -
Comment 1
Thanks for your reply. So, now does that mean the intake manifold needs to be replaced? There is a tiny hole - maybe a weak spot - and when the pressure built up a little piece blew out? Does the thermostat need to be replaced also...I had it replaced two years ago. -
Comment 2
ck it out in boiling water and yes intake leak will need to be repaired also -
Comment 3
I had the intake manifold gasket replaced. It's still leaking from somewhere because when I check the radiator level each morning (because it got hot again after that), I have to put about 1 cup of liquid into it. I can't tell if the leak is by the radiator or under where the hood meets the windshield wipers. There is no moisture on the floor inside; however, I noticed yesterday when I stopped, but still had the car running, there was a bit of "fog" on the inside passenger front window...now what, any suggestions? Thanks! -
