follow the bottom radiater hose to where it enters the water pump, you will see a housing. in this housing, that is held on by two bolts is where you will find your thermostat. its easier to get to underneath the vehicle

I would suggest taking this in for repair, you can buy the thermostat at any auto shop for under ten dollars. Finding a auto repair shop that will fix it is the hard part. I found a local mechanics shop that would do the job for eighty dollars, and i gladly paid him The thermostat is located under the Power Steering housing, making it a hard job, you will need two 13mm deep well sockets, a swivel, and an extention, and alot of patience. First release the bottom hose, let antifreeze drain, release three bolts to power steering housing, two in front, one in back, then will be the money shot, you will see the thermostat, from there it's simple removal and putting back together. good luck!

If the car has power-steering the power steering pump and mounting bracket have to be removed to get to the thermostat housing.

How do you replace the thermostat located on a 1992 VW Jetta GL?

If it is like my 1991 Jetta, follow the lower radiator hose to the water pump housing. There are three bolts that are very difficult to navigate around. The thermostat is located behind those bolts. Don't know why they put the therm there, cause it is a pain in the rump and could have been alot easier if they had put some thought behind the design. You'll see what I mean.

Where is the thermostat located on a 1994 VW Jetta 2.0L?

Ok, if you follow the main coolant hose from the radiator to the engine block you will see that before the coolant actually enters the engine block it goes through a plastic housing with two electrical plugs this is where the thermostat is located. One of the two plugs controls the thermostat (if not both). I had a problem with my cooling system ('94 VW Jetta GL III 2.0L) as well and had to find it on my own. I replaced the whole housing for approximately $35 and it fixed my problem.

You may find all you need in the Hayne's manual for your year VW, sold at most discount parts stores. I just bought one that covers the 1991 Jetta GL (and other models) at the local Advance Auto Parts store ($16.99), and the last chapter in the book has a fairly exhaustive collection of wiring diagrams. Happy motoring!
