The temp gauge was showing hot when the 160 stat was in. Thats what started me on this path.

If I rule out the temp sending unit, then I'm guessing its a clogged radiator or bad water pump???

Have you tried flushing the radiator? I know on my 86 with stock radiator you do see coolant moving. I would guess plugged up or the water pump is getting tired.

My money is on the water pump. Pull the top hose and see if coolant starts coming out as ot gets warm. Another less accurate trick is does your heat work

If I remember correctly, when I ran a hose through the radiator when I had it out a while back. There was flow but I dont remember how much. I have seen some suggest to take it out and fill it up with water with the bottom outlet plugged. Then release the bottom plug and water should shoot out around 9 inches or so. I didnt know about this at the time but may end up doing that if the sending unit is good.

Ugh! I hope not. Will ad this to the list to try. If it coolant doesnt come out much or at all, couldnt this also mean a clogged radiator?

If it were a clogged radiator, then you would have had coolant gushing out the filler when you did your first check for flow.

Remember, the coolant flows into the radiator from the top hose, and out the lower hose.

Oh, it's not so bad. Water pumps are (relatively) cheap, and not hard to change at all. I once changed my water pump in the parking lot after it went out on my way to school.

Ok, just got back from picking up the voltmeter. I will be checking the temp sending unit next but will have to save that for tomorrow.

Earlier, I was able to crank and immediately drive the CJ around the block (almost 1 mile) and by the time I got back the temp gauge was almost pegged on hot. Shut it off and checked the radiator cap a couple minutes later. No pressure noise, ans coolant inside was luke warm. But the top and bottom hoses and heater hoses felt hot.

So to check the water pump, I need to pull the top hose off the radiator to check for flow from the engine, correct??? Forgive my brain fart...I'm just tired and don't trust myself.

Yes but the engine needs to be warm so tbe tstat opens to allow flow

Test the radiator flow. Put the hose in from the bottom and see what comes out the top as well as the other way around. I had half of the mud flats come out of mine.
