Runs ok at sideroad speed. immediately overheats on the highway. loses 'kickdown power' until i turn it off and restart. i have access to a rusted out 2004 buick century with 3100 engine that runs fine. could that go in to the rendezvous in case this is a 'pinhole' head gasket leak, ir could the 3400 get away with new head gaskets?
Could be a blocked radiator and coolant is not circulating enough to cool down
Testimonial: "radiator was replaced with new"
Did you get all the air out,remove radiator cap,start up.let run until the thermostat opens,you will see the flow in radiator,put cap back on and fill overflow container to full.

Hey there,
I've just had an ongoing problem with my 1990 Pulsar overheating.
Mechanics checked everything: electric fan, airlocks, leaks, etc
Car continued overheating intermittently for months - finally the mechanic put a non standard thermostat in, one which activates at a slightly lower temp that stock.
Problem is now resolved.
Hope this helps,
Michael

double check the pump the impeller inside can be rotted away and it will still pump some but not enough to cool it at 65 mph , you can remove the pump and take off the plate on the back and look at it easily? second get a tech to loan you his infared thermometer and double check the temp it can pinpoint the problem ? good luck [email protected]

You did not mention if you replaced the thermostat. It may be stuck closed.

could very well be the water pump. they dont always leak if they are bad. sometimes the impeller that moves the water through the system fails.
