Any specific info. regarding Coolant DRAINING and BLEEDING procedures(1.9 NB) would be greatly appreciated...Thanks.
Good Idea!....Do you think the "MITY VAC" would do the trick?- although a bit tedious bec. the Mity Vac fluid reservoir is small, just wondering if it would work with the right suction tips.When I do it, I take my oil extractor pump and attach it to the drainback overflow hose that goes to the coolant resivoir. I apply suction to it and slowly add the measured amount of coolant. sometimes I'll also "burp" the hoses by massaging them to get any air bubbles out.
the red arrow points to the hose oldpoopie is talking about. Yes a mity vac will werk.to the drainback overflow hose that goes to the coolant resivoir. I apply suction to it and slowly add the measured amount of coolant.
Bleh cough cough.......If you use the mity vac you don't ever actually need to collect any fluid in the "catch can" In fact, before I found the above method, I would just suck on the hose with my mouth untill I "felt" the fluid coming
The GM Orange stuff is calld DEX-COOL and is referred to as "DEATH-COOL" even by many die-hard GM Fanatics.shr0Om said:... i replaced with the 100,000 mile "new gm" compatible coolant, it is orange... ive just found out this wasnt the best thing to do, but its been like this a year, my question is should i change it back to the orig stuff from dealer? ...
I recognized it was you from your juice-jug-technique you did on my car LOL!runonbeer said:well now. The drain cock is located on the drivers side and you must remove the belly pan and DS side skirt to get at it.
it helps to put a little hose on the drain cock and run it into an old milk carton or somthing. the drain cock does not simply spin open, rather, it cams out when turned CCW such that only about a 1/4-1/2 turn is required to reach the fully open point.
While draining, you may want to apply a bit of pressure to the coolant res. to push all the coolant out of the head.
once you've drained it all, make an assesment of how much was removed and then mix 1/2 that amount of new coolant with the same amount of water (distilled if you live in a region with high mineral, carbonate, sulfates like I do.)
Remove the clamp on the upper radiator hose that leads from the radiator to the drivers side of the head. there is a union at that point that is convenient for adding coolant.
first fill the radiator:
then fill the engine:
then, reconnect the two ends of the hose leaving a small wedge through which air can escape, and hold it thusly while filling the resivoir like so:
Slowly, the coolant will fill the block and push air up through the hose. Once coolant rises up to the hose (you'll see it) reconnect the hoses fill the res to the proper level, and start the engine. this will ensure that the water pump is never run dry and is effectively faster than waiting for the engine to bleed itself while adding coolant to the res.
Why are you changing your coolant? did you get some green stuff?
