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.

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!

Joven, pasos a seguir: this is an previous trend a thank you to examine the water pump. Wait till the vehicle gets somewhat chilly. turn the vehicle on whiles is on, on the decrease radiator hose is the place the chilly water gets in. the better hose is the place the nice and comfortable water comes out. on the better hose with the engine is on squeeze that hose for a pair seconds ( 30) you will experience on you hand the water getting push out. ( like in case you have been eating water) you''ll experience the water passing trought the hose. in case you do no longer experience something, you do no longer experience that the water is getting push. Then, your subject is the water pump. ( must be reemplaced). the different attainable subject is your radiator: i'm ninety 9% optimistic that the water would not flow becuase the trails on the radiator are blocked. you do not have sufficient flow on the interior. issues to do: Flush the radiator, in case you notice the water purple with little peaces of steel then you extremely could reemplace it. those are sign that radiator is rusted interior. (desires new) try those steps first and could see the way it is going. Please enable understand the form you fix it.

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.

I agree with Michael G, I believe those vehicles drained by removing the lower radiator hose.

You need to drain the radiator from the bottom using the petcock valve .... look hard enough and you'll find it.
