Hot Rods Over heating.

I'll check that however, I think....not positive, that I have a reverse flow pump. Waiting for confirmation...

 

Counter clockwise rotation pump. That one is for a Serpentine belt.

 

Great news! Thanks for your help, Mr48.
And thanks to everyone that offered advice. Tomorrow I'll get the right pump and take a test drive. I will report back with results . I work till 5 during the week...it might take day or three.

 

Cool Joe. I think you will have this problem licked.

 

Thanks, neighbor!

 

You got it brother. The reverse pump issue has happened to many. Keep us posted.

 

You said the intake had 4 bolts that is usually a vortec which has serpentine belt so it would have a rev pump

 

Ok, just got this waterpump from NAPA. I asked for a waterpump for a 1977 monte , thinking they used v belts . I opened it up before installing and I think this is reverse flow also. Does this look like reverse flow?

 

Sure looks that way.

 

I found I had a reverse rotation pump on a 400 Sbc in a previously owned 32. It never overheated but wanted to run warm. Funny thing is the car was built in 2003 and I got it around 2018. It had been that way since built even painted the same color as the engine. My Avatar car was getting hot Monday and I found it was over a gallon low on water. No obvious bad leaks but I hadn’t checked the level since I got it a couple of years ago and it spent 6 months in AZ this year if that means anything.

 

Then this thread just adds to my confusion.

I have a water pump somewhere off an ‘89 IROC that ran with a single serpentine belt. I don’t think I tossed it, should be able to come across it and pop the cover and post a pic for you.

 

FIRST problem a CHEVY in a Ford--- go on Ebay get a 3-4 row aluminum radiator with their shroud and fan
and have the fan as a PULLER and a good fan temperature control set-up
then you will enjoy your ride

 

change that radiator...

 

That new pump looks to be what is referred to as a "straight vane" pump in post #62 ("solution" note section) because the 'vanes' intersect the center of the shaft. That's what I think I see but I don't know much about pumps or what you have for sure.

 

If that pump is a straight vane, it will work either direction. Lippy

 

Here’s a factory ‘89 IROC WP, for reference. @Country Joe

 

I'm still learning about whether it is worth suggesting things....

 

Fellow HAMB Members,
I stand before you in shame and disgrace.
I have found my overheating problem. Thank you all that offered help. It was appreciated and did indeed lead me to the path of a solution.
And I feel every thread should have closure.
So, here is a picture of the engine I built below. Have mercy.

You gotta be happy it's an easy fix, and you aren't the first.....

 

I was pondering my engine trouble and the intake gasket being installed wrong crossed my mind. I thought naw.....maybe? So, I took the heater hose nipple out of the intake and shined a light inside, over at the port and then I saw that wall of blue, DAMN IT!

lol....I am relieved that it will be fixed with a new set of gaskets and an oil change.(trapped water went inside when I removed the manifold)

 

I haven't personally seen that happen but now that it's in my mind, something to think about for future problems ,glad you found it

 

Good man! Letting us know the solution, even if there's a bit of humble pie involved. Just look down, kick the ground a couple times, order a new set of gaskets (install this side up, this end to the front) and rejoice in your new cool running ride.

The story at lunch or breakfast with your hot rod buddies will be good for a few yucks for years to come.

 

Thanks!
Buttoned it all up this morning. I'm going to start the engine tomorrow to give the silicone(or whatever it was that came with the gaskets) time to fully cure. Then take a drive. I am optimistic that it will stay cool.

 

Well*....***..... That there pulling the heater hose nipple and taking a peek is a pretty good tip, in any case.

 

Thanks!
If at the very least, I now fully understand the cooling system better than I ever have. Seems like kindergarten stuff now..lol

 

Thanks! I think it helped visibility that I only had clear water it the engine at the time. If it was still green liquid I'm not sure I would have seen it.

 

Mistakes suck, but they also include a good learning curve. Takes a big person to admit theirs, gotta love the simple fixes!
