Good day Sajeev,
I’ve a 2004 GMC Envoy, four.2-liter six-cylinder, with about 123okay miles that appears to be leaking coolant from someplace across the radiator cap. Each time I come to a cease with the home windows down or pull into the storage I can scent antifreeze. The radiator seems full and the reservoir appears to be sustaining a reasonably constant degree of the pink stuff. It by no means leaks sufficient that I see moist spots besides at times across the cap, and even then it’s just a few drops at most. I’ve taken it to the mechanic; they double checked all of the hoses and connections and even changed the cap, nevertheless it didn’t assist.
I changed the cap a second time considering I acquired a foul one, however the scent stays. By happenstance the cap I purchased occurred to be the very same model the mechanic used. I’ve connected an image of the engine bay displaying the areas the place I can see dried coolant. The perplexing half to me is that, judging by the splatter sample close to the oil fill and the air filter field, a few of the coolant appears to be making it to the fan. Nonetheless, I by no means see any moist spots main in that path. Do you have got any solutions?
As a facet query, I’ve been getting an intermittent CEL with an related P0526 code (fan velocity sensor). It’ll come on for a visit or two after which go away by itself. Any probability the supposed coolant hitting the fan could possibly be inflicting the CEL?
After a lot googling, I’m confused. However your boy Sanjeev will get paid to kind them phrases on the autoblogosphere, so let’s take into account doable eventualities:
Oooooh rattling, son.
A pal jogged my memory of that downside when Baruth and I suited up for an endurance race: one of many racers (not me, not Jack) ran the motor sizzling, popping the top gasket. It wasn’t a colossal failure (but) however when the group chief began up the motor with the radiator cap off, we knew what went south. Like somewhat slice of Previous Trustworthy, the automobile’s radiator shot out water like a geyser.
So do the identical: begin the motor (WHEN COLD!) with the cap eliminated. Search for bubbles within the coolant, however be careful for geysers. Perhaps put on goggles — higher secure than sorry.
