Now i have another problem, but this time i am going to do the repair work..,

the temp. gage seems to be on the high side, but the engine does not seem over heated, when sitting at a traffic light the needle pegs out on HOT !! at 50 MPH it cools a bit, but not much, when i got home, i sprayed the radiator with cool water, the temp gage did not come off hot, i veeeeeery slowly removed the rad. cap, no pressure ! i dipped my finger into the coolant and it was like very hot coffee, not what you'd expect from coolant that pegs the needle at HOT !

the water pump has been squealing for for months, is it possible that the W.P. is not pumping ?? there seems to be no movement in the coolant when running or is the temp sensing unit bad ?

a new water pump is $45.00 and a lot of work, a temp sensing unit is about $10.00 and very little work, BTW the rad. cap is new...

what suggestions have you fellas and gals got ??

i would say it sounds like a water pump. but i would get it up to normal temp and look in the rad. if the coolant is not moving then i would put a water pump on and a thermostat in at the same time. just my 0.02

Sounds like the water pump bearing is seized. Replace it, it is not as hard as you think.

Be careful what brand pump you buy. I have put three on my truck in the last year (Autozone gmb pumps = junk). I finally put a motorcraft pump on there and have had no trouble since.

thanks guys ! i did what you suggested and it looks like a water pump is on order and will be changed today or tomorrow, thanks for the thermostat replace suggestion as i almost forgot, it is abt. 10 years old and too high for the Arizona weather.

You can also stick a thermometer in the radiator to see the actual coolant temp. as F1rocco pointed out, get a good set of aftermarket gauges. I run the Autometer Autogauge kit #ATM2348. $43 at Summit.:thumbup

water pump replaced, thermostat replaced....., BUT !! with a 190 degree, that is too hot in my opinion, but that is what the Checker Auto person found in the computer, i said i want a 180 or somthing in that range, she told me there was no other recomendation, so rather than stand there and argue (i was very aggitated at this point and completely out of patience) i bought it, but it wil be soon changed

I think you're right; 190 is too hot for that motor. I tried that in my 429, & it was too much. 180 works much better for me.

BTW, that thermostat fits many different applications, so you can find many different temp ratings. Don't let that fool at the counter tell you there's only one choice :wacko
