I ordered the stant adapter for newer chevys, the 12032
. It should be here tomorrow. I'll do some tests and see if I can find any leaks under pressure. I doubt that I will be able to see anything since if there is a leak it's really small but we'll see what happens.
I'm going to go ahead and change the coolant also. I'm a believer in fluid changes, they are fairly cheap and not really hard to do. I like to drain the radiator and then fill with distilled water and run up to operating temp and repeat a few times in order to do a DIY "flush". Then fill with the correct mix of dexcool to get it back to a 50/50 mix. I haven't looked at the capacities for this engine yet, just picked up 2 gallons of dexcool and some distilled water for now. I can usually get it pretty close and double check it with a snap on refractometer to make sure it's the right mix.
Also going to flush the brake fluid. I"m not sure what GM recomendations are as far as intervals but there are a few car manufacturers that recomend every two years so that's what I like to do. Brake fluid is cheap and I bought a mityvac brake bleeder a few years back, http://www.tooltopia.com/mityvac-mv6835.aspx
which makes quick work of changing out the brake fluid. Anyone know the correct bleeding order for this car? I ordered a factory service manual but not sure when that will get here.
Also will do a trans drain and fill while I'm under there.
So that is my plans for the holiday vacation! Any advice is appreciated and if anyone would like pictures or even a little write up I would be glad to do that.
