First, thanks to all who contributed advice as I rebuilt an ‘86 over the winter. It runs well. However, I have a new problem.
The engine overheats soon after cranking. I replaced the impeller and belts and the pump is turning on the spindle.
Anyone tell me what else the problem could be?
Is it possible I re-mounted the pump backward or does it matter?
Many thanks in advance.

New/functioning thermostat? Do you know the sender and gauge are good?is this sitting in the water or on the hose?

Make sure you mounted the raw water pump with the hoses lining up on the engine side. Are you getting water out of the exhaust?
Ok. Thanks. I’ll check both.
Where is thermostat located?
Front of the motor, look for where three 1" hoses come out of it. A 2" hose from raw water pump comes in below. Sits in front of distributor slightly off to left. Should see 2 Allen wrench type bolts.
If it wasn't new then take it out and put it in a pot of water on the stove. Measure the temperature of the water when you see the thermostat start opening to verify it's working correctly. Verify the temperature at which it is in full open position.

post a pic of how your raw water pump is mounted now
Tried 30 mins to figure out how to send a pic to no avail. I’ll report back later. Thanks for hanging in there with me.
I post pics to Imgur then copy and paste here. Text me the pic 678-227-8833
Water pump likely on backwards. It goes on the opposite direction it seems like it should.
On my 89' Conbrio, I pulled the pump in the early summer to check and clean it and I put in back on backwards. Engine started getting warm and I knew I had done something wrong. Went back, switched the pump around and it ran cool as a cucumber like always. Thats what happens when you get in a hurry.Quote:
