Hi Mike, here's the instructions from the manual. Let me know if you have any questions.
Removing Note: Always replace O-rings, seals and gaskets.
Unscrew mounting bolts -4- of connecting flange -3- and remove connecting flange -3- with thermostat -1-.
Installing Installation is carried out in the reverse sequence, when doing this observe the following:
Moisten new O-ring -2- with engine coolant.
Install connecting flange -3- with thermostat -1- into engine block.
Note: The brace on the thermostat must be almost vertical.
Tighten mounting bolt-4-.
Tightening torque: 15 Nm (11 ft. lbs.)
Fill with engine coolant.
its taking forever to get heat into the vehicle.(if not any). Im hoping its the thermostat and not the heater core under the dash. What you think?
can you give me a diagram of the heater core?
I got the thermostat in..but i brook the dip stick holder..man that was brittle!!I guess that would be a dealer part.. Now do I put the antifreez in the round resivor on the side?
The dipstick tube should be readily available from the dealer. They break easily. The part # XXXXX XXXXX 103 663C. It's a $9.00 part.
Yes, you would add coolant to the round reservoir. Use only VW coolant or the equivalent.
WARNING: Steam can be released when the cap is removed from the expansion tank. Cover cap with a cloth and open carefully.
I would NOT recommend trying to replace the heater core yourself. It's very very labor intensive and requires major disassembly of the dash. If you still have no heat you need to unhook the hoses and flush through the core with some fresh water. If the core is indeed plugged then replacement may be necessary. If it flows well then we need to look elsewhere for the problem.
It looks like the session times out in 24 hours. I'll still be available however. Sometimes I just don't get the email alert in my personal mailbox if it's timed out already and you'll have to rely on me seeing it in the general mailbox. You should contact customer service for clarification on that.
I replaced the thermostat, ran water through only one heater core hose (could not reach the other hose) i figured one was better then none. The vehicle is putting out some heat, but not as much as its capable of. What ya think?
