Coolant Loss

[jmildoc]

what kind of antifreeze can I use? Prestone?

a cup of coolant may or may not be enough to have the level to your hot level in the reservoir. all that a cup may have done for you was put enough liquid in the reservoir to float the switch up to turn it off. you CAN put dexcool back into the truck OR you can do a full system flush and go back to another antifreeze, but you'll have to make sure all of the dexcool is flushed out of the radiator, engine and heater core....ie the entire system.

If you have DexCrap in there now, you might as well stay with that.

If you've done a complete flush, I would go with the G-05 yellow coolant.

IIWY, I would just add DexCrap. The way you described the degas bottle, tells me it's Gen1 DexCrap.

its most likely dexcool... thats what GM uses these days, its what i have... i have no problems but i also have no education on the matter... whats the problem with DexCool guys? why is the yellow shit better or is that just personal preferance?

I have a VERY small leak under my throttle body somewhere (not the TB coolant bypass either) and i have to add coolant in about twice a year. I just add 50/50 DexCool.... i wouldnt be apposed to doing a flush and changing fluids if i thought my truck would benifit from it though

How will someone flush out all the coolant, is there liekea drain plug?
Just wondering.....

 

[jmildoc]

you can buy a bottle of radiator flush that cleans it out....

My fluid is Yellow.... So I guess I can use any kind. I bought a tester and am going to see if its still good...
