Hey guys,
I’ve been tinkering with a 2012 Jetta tdi. It has an overheating problem but I have not a clue why. Blows nice hot air so I doubt the t stat is stuck. Changed the water pump and all that so I know that’s ok. Upper rad hose gets hot and lower is cool. Fans come on. No pressure in the system from what I can tell and never boils over in the expansion tank. I changed the temp sensor just to see if that would be it and its still getting hot. It will go up to 100c at idle and climbs over 122c(coolant light comes on) and rising when driving. My next step is to pressure test the coolant system. Anyone else run into a similar problem?
