Hello fellas,
Ive got a 2013 gu713 with a mp8 in it. Recently I've noticed that the engine oil tempature is rising up to 266 when loading in a hard pool, down the road loaded it'll linger around 255-263ish. Before the last week it always ran at 244 when loaded. My water temp has been getting slightly higher than average, around 209 at a hard pull when loaded and the fan will kick on and drop it back down to around 190 but it'll raise pretty quick again and just keep doing the same process. Truck still seems to drive well.
Now.. my coolant has also gotten dark as well. Like a purple blackish color. My mechanice tested it and flushed the coolant system, he said there wasn't any pil, transmission fluid, etc mixing. The coolant level is also dropping below minimum even tho I filled it all the way up and haven't ran it since 2 days ago.
Sorry for the long message but im worried about the truck at this point. Its been nothing but a headache. What could be my issue here?
