I'm in the midst of changing out a bad thermostat on my 1996 2.2 ltr 4cyl Pontiac Sunfire... I've found the housing for the thermostat and am ready to go as long as I can find out how to drain the existing coolant from the engine.
How do I do it?
Thank you for any help you can give me.How do I drain the coolant in my 1996 Pontiac Sunfire 2.2?You're going to get some spillage no matter what you do, but you really have to drain all the coolant out of the engine AND the radiator to keep from having a huge mess. Most GM cars have a drain cock on the bottom of the radiator, but unfortunately, they usually get stuck and are made out of plastic, so there's a good chance you'll break it if you try to force it. The easiest way to get the coolant out is to loosen the clamp on the hose that goes to the bottom of the radiator and pull the hose off. You'll need a large pan to get all the coolant, and it is going to splatter, but it's really the most efficient way. Good luck!How do I drain the coolant in my 1996 Pontiac Sunfire 2.2?You need to drain the radiator from the bottom using the petcock valve .... look hard enough and you'll find it.How do I drain the coolant in my 1996 Pontiac Sunfire 2.2?There should be a drain plug in your radiator which this will be located at the very bottom of it. When you drain it make sure that you catch the fluid in some type of container. Coolant is very poisonest to the environment as well as animals since it smells and tastes sweet to them. It is a very sad thing to see this type of poisoning in an animal. Causes convulsions, nerological damage, froathing at the mouth, and so on. So please keep this in mind when doing this.How do I drain the coolant in my 1996 Pontiac Sunfire 2.2?i dont think these newer cars have a petcock drain in the radiator i know mine dont its a 92 you just have to take off bottom radiator hose that should do for changing the thermostat.How do I drain the coolant in my 1996 Pontiac Sunfire 2.2?I agree with Michael G, I believe those vehicles drained by removing the lower radiator hose.
