Overheating

[laguna]

I put this in mechanical section but figured it couldnt hurt here.

I have a 2003 24v and it is overheating at high speed at 2000RPM or lower there is no issue. So i replaced the impeller first that did not work. Then i went through the pick up and all the lines to make sure there was no blockage and there were none. Then i took the thermostat out to see if that was it and no luck. Any help would be great.

What motor do you have? circulation pump gone bad maybe?

circulation pump is my guess.. known to go bad. think they are like 89-90 bucks.

or you could have a blockage in the exhaust manifolds?

i assume that means the water pump thanks for help.

no... there is a water pump(where the rubber impellar is).. and on the front of the motor a circulation pump.

might have weeds stuck in the heat exchangers on the lower port side of motor.
