Try bleeding the air out of the cooling system and see whether it helps, also at night time start it up and look at the exhaust manifold is it glowing.
Last the fan clutch could be slipping-that's if it has one.
Running it w/o the Stat is not a good idea, the computer needs the correct temperature from the coolant temperature sensor to fine tune the A/F mix.[/Quote:a5e66a3439]
I checked the exhaust manifold last night, no glowing. I forgot to mention I already changed the clutch. That was the my first thought also. If it was a radiator or water pump, would the engine get that hot that fast? I only removed the stat to see if it would take longer to heat up. Which it should. Makes me lean towards a bad pump, but I still don't understand why the engine gets so hot so fast. Thanks for anything you can add![/Quote:a5e66a3439]
All it takes is 5 mins. For an engine to overheat stationary. Sounds like circulation problem- Remove the cap fill it to the brink don't put the cap back on, now start it up-is the coolant swirling around. Now squeeze the upper hose for a few secs-let go -did the flow increases-
Check the radiator fins it should be evenly warm across-they shouldn't be any cold spot.
