Overheating

I tested the t-stat before install and it’s operates, the fluid was filled to top

 

Oil pressure is about 6-10 at cold start it’s low but bumps up to 6 and when high idle kicks off it’s about 8-10

 

I could replace the grille with a mid 70s which would be not as deep and put that radiator that goes with that grille, then I can put the fan as a puller style right? I can switch the fan blades around.

 

Yes I talked to my buddy here and I think we are going o do that as well as I may look at the water pump as well, seems like it takes awhile to get to 180, have to get RPMs up a bit to raise the temp, then the fan comes on and t-stat opens. What’s your thoughts on Changing the A1 style grille to cj5 grille? I could swap radiators and put the puller fan on instead of pusher?

 

Before I did anything else I'd spent $10 on an infra-red remote thermometer, and double check if it is truly overheating. Useful for many other things too

 

I filled it abou 1” above the coils. I looked in it today and it has plenty of coolant in it. Has room for expansion. I need to look for a CJ5 grille. I think that’s a way to go to Change the fan location. Or cut the cowl out of my A1 and mount the radiator to the skin of the grille.

 

You can't change the blades. Just wire the fans backwards.

 

X2 what Scott said.

They'll run the same either way you mount them. Can you reverse the polarity?

 

Not according to Hayden who is an electric fan manufacture. See section 5 of the attached installation instructions.

Read it all. It says to reverse the wiring too.

The fans may have a front and back, but flipping them cannot change blade orientation. Try it.

 

Double-check your fan rotation. With the fan “on”, put a piece of paper up to the grill. Does it suck toward the grill, or blow away from it? Either way, pusher fans are very inefficient.
Also, your oil pressure is too low. There is a cap on the oil filter housing that has a spring under it that controls a by-pass plunger. If that plunger is sticking, or doesn’t seat, your oil pressure will be too low. The plunger must be seated (closed) until the oil pressure overpowers the spring, regulating the pressure to around a max of 50 or 60 psi.
