I recently overheated my old stock 22re motor and ended up buying a rebuilt 22re motor at a shop. The stock motor had 214k miles on the thing. The problem is when I am driving at 65mph or idling the temp. slowly raises to 210 and stays around that area. When i am driving at 45mph the temp. stays around 190 but sometimes hits 200. I replaced the fan clutch, put it a 180 degrees thermostat 3 times, flushed rad. twice, bought a new rad. cap, and cleared all air bubbles by taking off the rad. cap and turning on the heat to FULL. I am not really worried about it staying around 210 since the motor still seems to run normal but when living in arizona and temps hit 115 degrees outside I really want to use my ice cold A/C but when I turn the A/C on it just raises to 220 and above. Im stuck and dont know where to turn now. Hope I gave a good description of my problem because im a newbie mechanic. Any help would be great thanks.

 

I live in Glendale so I know how you feel. I wonder if your cooling system has a blockage thats slowing the flow of coolant down, like your radiator might be plugging up. Check your belts and belt tension too.

 

Sounds like my '85 was doing when it had a partly clogged radiator. Take a peek inside the cap and see what the cooling passages look like. I put in a new GoDan 3-row radiator and it has run cool ever since:

I really think it is the rad too. I think ill take it to the shop for them to test it. The link you gave me dont work?

 

If you are referring to the link I posted, it works fine. What sort of error message did you get?
