Temperature question

[Grandavi]

Excellent tips. I replaced the coolant line that runs to the turbo last year, maybe that is the issue. I could have an air pocket. I am getting the system flushed/filled so that might clear it up. That hose burst on me last summer and I lost most of my antifreeze on the road (fun).

I am not sure I want to try the sealant for the heater core, strictly because of the age of the car (88 MKIII). I am thinking that if I replace the hoses to and from along with recoring it, that will just stop any issues from arising for the next 5-10 years (or more). I currently get a greasy "fog" on my windshield if I put the temp to 24 deg and you can smell coolant. It is probably only the valve that is leaking, but like I said.. its a 22 year old car, so probably not a bad idea just to recore it. I dont mind putting coin into the car. Its my last one if it lives as long as I do. The wife can have the newer vehicles. This is my baby. : )
