~~~water pump question!!!!~~~~~~~

I have an 89 Blazer 4.3 4x4 that a week after I bought dropped a rod.I put a new motor in the problem is, it is a 93 4.3 tbi out of an astro. My old engine was v-belts...the new once has a serpentine. I had to switch pulleys and the fan over from my old motor. I know that the fan spins in the oppostie direction on a sepentine and v-belt, but I put the water pump off the v belt motor on the serpentine. Would this mean my water pump is spinning in the wrong direction causing me to over heat or constantly run above half the temperature gauge? Because either I am over heating or I am on the hash mark just below over heating unless it is freezing outside...but if I gun the motor once or twice my temperature will go down from over heating...I am stumped...any inquiries would help me a lot thank you.

You need to match the pump and fan to the proper belt. They are both direction sensitive.

You used the old water pump??? from your blown engine is that what you are saying or the pump that came with the new used engine.

Thank your for the help and I know i worded it funny I just read it and confused myself...lol I meant that I used the water pump off the old motor because it was brand new and switched the pulley and fan blade.Sorry bout that.

Go get the correct pump for the new used engine.Check at the parts store if the pumps are different for the 2 engines if so get the correct 1
