Refill the coolant tank and put a bottle of GM's Florescent Coolant Dye. When the coolant leaks out again - and it will - you'll see residue from the dye. This will help you pinpoint the leak.
Dexcool is red. The A/C refrigerant is green.Interesting, I found the majority if not almost all the coolant residue on the engine mount? near the bottom of the radiator fan. See attached.
Yep, you've got a freon leak - it has a flourescent dye in the system to make leaks easy to spot. Sadly, a rock punching a hole in the AC condensor seems to happen quite often with these cars.Dexcool is red. The A/C refrigerant is green.
Ah ok. It's the exact color of the AC stuff, but yeah, you probably wouldn't see that there.Now wait I second, I just put the coolant florescent dye in a day ago and that's when that showed up, so I think it is actually a coolant leak, unless my freon is leaking too.
The GM coolant dye is red/orange and makes dexcool turn a muddy red color. Your leak is green - you have an A/C Freon leak. You may also have a coolant leak based on the first set of pictures but that last picture is definitely Freon. I had a Freon explosion in my Montana and the entire engine bay was bright green.
If that's passenger side, we could be looking at water pump.Interesting, I found the majority if not almost all the coolant residue on the engine mount? near the bottom of the radiator fan. See attached.
Very definitely not the right color for dexcool. I can't even begin to guess what would turn dexcool green so I would guess you have the old style coolant in there.I am not typically the argumentative type, but unless the tech put the wrong thing in, it turned my coolant green. See the photo of my tank attached.
Now you understand why I thought that was freon and not dexcool.I am starting to question if it was the correct dye; Only turns green when the dye was put into it. The coolant is Prestone G.M Dex cool approved antifreeze/coolant. Anyways, back to the task at hand, the leak spots are happening on the drivers side. I am thinking about placing a mini camera down there over night. In fact, I am thinking I should flush it.
I have a jug of Prestone Dexcool and it's orange.Dexcool is the marketing brand for GM. You can use the green color since they now are all the same. Go to any auto store and they state right on the jug works for all types. There might be few exotic cars that use a different type but green or red doesn't matter like it use too.
Makes me wonder though why its that green though?
