91 Cavalier again.... - Coolant Issues

Having owned a 90 Cavalier with this same engine my guess is you're about to experience the blown head gasket syndrome which this engine is infamous for.

What do you mean by "smoking"? Tailpipe smoke? Or the engine smoking? Or steam? Where was the smoke coming from? Dave

It's engine smoke from underneath the hood.

That's what my dad is saying. He's also saying that I have an external coolant leak because the head gasket is gone.

I HAVE THE SAME MODEL AND ENGINE I HAD THE SAME PROBLEM ITS A BLOWN GASKET WHEN I CHANGE MOTORS THE HEAD BOLT WAS CRACK THAT COULD BE THE PROBLEM TO THERE SOME STUFF THAT YOU COULD PUT IN IT TO SEAL UP THE GASKET BUT IT WONT LAST LONG IT WILL LAST ABOUT TWO WEEKS WELL ANY WAY I CHANGE THE MOTOR AND AND ABOUGHT 2MONTHS IT DID IT AGAIN BUT IF YOU WANT TO TRY ITS CALLED MOTOR SEALENT SORRY IF THIS DONT HELP U

Is it actually overheating now? These engines were known for external coolant leaks from the head gasket, maybe it's just leaking there. If so, you're going to need to get the head gasket replaced.

keep it simple sayeth tim this way you dont need any shift or punc keys and if you have the same model and engine as tim you must have the same problem change the motor and of course you must have the same problem
