JA: Thanks. Can you give me any more details about your issue?

Hi, I’m Ron and I can help you.
I have been in this business since 1975 and also teach automotive repair. I am confident we can resolve your problem together. Please understand that I don't know your skill level. I can't see, smell, hear, or touch the vehicle either, so it may take a few replies to get to satisfactory results. Please be patient!
I also try to give all of the information you may need, expecting a “positive rating” in return. I will also continue assisting you after you have rated me, if necessary. If there is any reason I cannot get a positive rating, please let me know why “in advance”, so I can go another direction for you. I am sorry you’re having this problem; I’ll help you through it.

Ok, this interruption from the exhaust gasses in the cooling system is not good and needs to be addressed. The water pump can also be a problem if the fins are deteriorated that you can't see from the outside.

Thanks, Ron

Well i'm questioning , what should I be looking at? I mean I can check water pump. The temp gauge will sometime overheat. All I do when this happens is shut off the engine for a few seconds and restart and that goes away.

It sounds to me like a restriction in the cooling system and now that I know about the exhaust gasses issue, that needs to be fixed first and foremost before trying to diagnose anything else.

Thanks again, and please don't forget to rate me and keep this link in case you need me again later on.

Ron
