How do I t-top a 03 Pontiac aztek radiator - Pontiac Cars & Trucks

Better to do that with a high end scan tool. You can't do it by disconnecting the battery overnight, but that can cause all sort of new problems. Where you say your speedometer 'sets' at 55mph, do you mean always stays at 55 even stopped, or do you mean if 'sits' at 55 even if you are doing 110?

The most likely cause of all this the VSS (vehicle speed sensor)

okay this is a job and the a/c system needs to be evacuated, then vacuum the system and recharged when done. step one drain coolant and remove the fans with the shroud.remove the radiator hoses, next remove the lower ****** oil cooler line from radiator.
Evacuate freon from a/c system.

remove the nut that holds the a/c discharge line to ac condenser block,then pull line off block,
remove the bolt that secures the evaporator inlet tube to block.
disconnect evaporator inlet tube from block.
Remove the condenser and radiator asm out .
separate condenser from radiator.

reverse to install.

you have screws in the steering column, take those out then you have screws in the ignition. Once you take those screws out the ignition should slide out and then just reverse the process.

IF YOU TAKE THE WIRES OFF THE BATTERY IT SHOULD RESET ALL SENSORS

it could be the radiator isn't working properly, I had that problem with my Dodge truck and even though my radiator had been replaced two years earlier when I took it to a radiator shop I discovered it was bad and that was the problem the whole time.

remove coolant.remove thermostat remove bottom radiator hose to water pump.put a empty container under the radiator.take a water hose put it where thermostat goes flush out the rust in block.watch the water as it come out the water pump .if stream water is small keep flushing until you get a study sream of clear water. also flush out radiator. lower water pressure dont flush radiator it with high water pressure you could burst it. make clean the over flow jug .make sure it not stopped up.put in a new thermostat and radiator pressure cap. fill radiator with half antifreeze and half water.bleed the coolant system.

ok, i'm gonna take a stab in the dark- i have never seen teh motor of an Aztek, but you should remove the fan shroud, remove the hoses- top and bottom- remove the screws from the brackets and it should pick strait up.
