Good Morning,
Wanted to see if I'm looking at a semi-common issue.
09 CR Jetta
136k
Stage 2 car (DPF delete, tune)
Stock otherwise.
Timing belt was changed about 6k ago (friend and I did it). Didn't want to do the water pump yet as we didn't have a good way to purge the air out.
Not sure if the coolant is breaking down, if the water pump is needing changed, the heater core is starting to plug. Or the thermostat is starting to stick some.
What's happening is, its been extremely cold here lately (Michigan). Semi slow to warm up, but doesn't over heat at all. Gets to 190F and sits there, but when the fan is turned on above position 2, while driving it will slowly lose engine coolant temperature.
Maybe I'm paranoid but just wanted to see if anyone else has seen this or heard of this. I don't have any hand tools up here (live in an apartment), more or less just asking if anyone else has seen/heard of a similar problem happening.
