You might have a chance to repair this engine. Remove all of the sparkplugs, use a can of WD40 of similar lube, give each cylinder a good blast. Use a breaker bar and the appropriate socket to "work" the engine back and forth via the harmonic balancer bolt. Once you have the engine to the point where you can rotate it fairly easy, you can put the plugs back in and try to start it.

Why is my radiator fan staying on constantly until i turn off the car.

Hi Sian, I'm AL the owner of Big As Auto Repair in St Charles Mo

I look forward to helping you.

Sian, your engine is overheating and this is a crucial issue. This problem can damage you engine do not let it run very long until you find out the problem. First: VERY IMPORTANT for your safety, wait until the engine cools completely at least an hour, then take off the radiator cap, if you only have a recovery bottle make sure there is coolant in the radiator or recovery bottle. If there's no coolant top off the coolant and see if it overheats again. If it is full of coolant you can try changing the thermostat and see if that stops the overheating. To answer your question the fan is running all the time because of the overheating issue, its trying to cool down the engine. Hopefully it has not overheated enough to warp the heads or damage the engine. Let me know what you find and for further help click here: Auto Repair

They tell me my Sonoma 4.3 is locked up but it never overheated and it did NOT clatter. can't get flywheel to turn. ???

did you try removing the serpentine belt to see if the alternator or another accessory is seized? With the belt removed try spinning the crank by hand. if it moves with out the belt on than one of your accessories is frozen up. Since you said you ran it off the battery I would have to say that possibly the alternator froze up, which is not uncommon for a gm truck.

My 2008 Acadia is overheating. About 6 months ago it overheated but cooling levels were fine. Nothing was repaired and everything started working as expected. Yesterday, it started overheating again. ...

it sounds as though your acadia may not actually be overheating, it sounds more like the tempeture sensor is bad, if its "froze" at a certain reading this could fool your computer, you should be able to replace this part for around 20 or 30 dollars. hope this helps

Over heating problem

One possible cause could be the heater core. I would back flush the heater core to make sure it is not obstructed. I really find it hard to believe 3 motors would all have bad head gaskets. I hope this helps and have a great day.
