My 1998 Chevy Lumina says there is a special filling method for the antifreeze, How do I do it?

Answer 1

The best way to do it is to park the car so the RF corner is the highest point. Locate the air bleeds on the system as you will need these later. The one that makes the biggest difference will be on the thermo housing or close to it if available. If not, don't worry about it. Add your gylcol to the system being mindful that it is supposed to be at least a 50/50 mixture. Just fill it right up and watch as it slowly burps down. Patience is good here as there are lots of areas where an air pocket can stick. When you get it to the point that the air will not bubble up anymore and the coolant level is full, start the motor and let it try to circulate out any air for you. If it does, great, top it off and you're done. If it seems to try to boil over stop the motor and either let it cool down by itself or carefully open the air bleeds. Either way all you have to do is get the air out.
