Maybe someone in the west forum can help me out faster...

I'm having some coolant problems. Recently a coolant hose on the side of the block, right next to the oil pressure switch started leaking and it eventually tore off while on the freeway. The temp when way up and I stopped the car and pulled over and fixed the problem. I ran the car for about 2 weeks after that and then my temp all of a sudden rises. I replaced the cap with an OEM one and before I replaced it I checked to see if I had the 'dreaded' bubbles in my system, and I let the car run until normal operating temp and no bubbles were coming out.

I looked for other possibilities and found a test to check if the water pump was faulty. I turned the car on from cold and let it warm up and then I pinched the uppper radiator hose and it was very hard and I felt now change, not even a slight surge in pressure as I released it. So this led me to believe my thermostat was not opening. So I also replaced that with an OEM one and still does the same thing. After I shut the car off I can hear boiling by the thermostat housing. Some water going back into my overflow tank. I might have an airpocket since that last hose tore open and made me leak a lot of coolant, because all I did was just top off the anti freeze. So I'm wondering if it could be a bad water pump? Does anyone have any symptoms/observations they have seen from personal experience?

I could be wrong but I think it could be the water pump because when I turn the car on and let it sit there and temp does not go up at all over normal. Not until I drive the car is it that the temp rises above normal, and I give it a nice rev and temp comes back down (not even sure if I should have done that). So im thinking maybe the pump fins/rudders are so corroded that they are getting stuck and causing the water to stay above right where the thermostat housing is. I bought the car a few years back and the original owner said the pump was replaced but to tell you the truth it might have been replaced with a used one , because the motor looks spotless no grease/oil no leaks nothing and the pump looks really old and rusty.

BTW: The car is an 89 Gtu.

Thanks in advance...

 

when you 'fixed' it off of the side of the freeway, did you properly bleed the air out? Heater all the way max, and bleed it.

 

I did that today and I'm not sure if I got all the air out....Stood there with a funnel and had it filled just running the car without the cap and funnel for a while....But I thought what exactly is it supposed to do? Do I wait until all the water goes down? ??How do I know if its been thoroughly bled? I did it for about 15 mins and ran the car and it was fine...seemed like it until after that some driving the temp gauge would slowly elevate...then come down back to normal. The coolant is being put back into the reservoir tank. So I don't know if thats air or im fucked....Let me know....

 

Any other suggestions...?

 

so what's your questions???

 

he said, he wants a Wacko dance.

 

That and I wanted to know if anyone knew wtf is going on with my coche.

 

by reading further into your story book, i think you are fucked!
you are fucked because you were driving on the freeway and noticed the temp was high.
the question is, how long was the engine temp high before you noticed it?
also, since you replaced most of the occuring signs, and still doing it, YOU ARE FUCKED!!
the chances on the H2O pump is very slim.

 

you should "Junk It" before its too late. No need to spend anymore

 

I provide junking and gutting services for 2nd gens

 

Where do I sign up to junk it?

 

Just PM me, I can gut that thing into an empty, non rolling shell in about a day. Then chop and junk the shell in a weekend. All of this at no cost to you!

If coolant is not getting sucked back out of the overflow tank when the engine is cold, I bet you have a nice dead motor with a break in the coolant seal/groove somewhere. If you overheated it hard( which I think you did) I wouldnt be surprised for warpyness or a crack somewhere.

 

Well it does get sucked back into the readiator after it cools down. And I didnt run it for a long *** time when it started getting hot. I was changing lanes and saw a puff of smoke come out the rear and smelled coolant....so I drove like 15-20 seconds after that and pulled over near an offramp. The temp wasn't even all the way to the top it was about 3/4.

 

no, you should sell it to jj, so he can junk it after he changes his mind
