My sincere thanks to Passatsyncro for the info about having to remove the timming belt to get to the thermostat housing.
Can I use a camshaft alignment tool to keep the camshafts in time(meaning exactly where they are now) and then just loosen the tensioner to the point where the timming belt will slip off the left camshaft sprocket so I can take off the housing and get to the thermostat?
Also, is the alignment tool a special order from VW, or can I just buy one somewhere?
Also, will the timming belt and/or the crankshaft move if I push the car in neutral (it is an automatic) all the way into the garage (it is halfway sticking out of the garage now, so I wouldn't get rained on) but I need to get it all the way inside.
BTW- There must be a more logical method of engineering so you don't have to take half of your car apart, and put back together, just to REPLACE A THERMOSTAT!

it involves removing the accessories at the front of the engine, quite often a motormount, belts harmonic damper, inner fender cover, etc, you will need assorted tools, wrenches, long and short sockets,and patience, get a detailed manual, and good luck
the thermostat is located behind the timing belt so you should think about changing the timing belt, water pump, and thermostat.----Thermostat is on the back of the cyl head up at the bulkhead, follow top rad hose back and you will find thermostat housing. If you have to ask, you probably shouldn't be attempting it. It involves a lift, draining the coolant, removing the front bumper, putting the core support into the service position, removing the belts, moving the alternator, loosening the mounting plate that supports the fan clutch, power steering pump etc. - all so you can get to the thermostat housing! If you had a Jaguar, changing a thermostat would take less than fifteen minutes. Instead, the Germans audi car made it a four hour job for a professional too.
Your timming belt has jumped a tooth.Remove the covers and check that all teeth are ok.Then tighten or change the timming belt.I would fit a new timming belt.Has it is costly when they fail.Good luck.pippall.
First remove head and fix the bent valves. I have worked at a Daewoo dealer. People would buy the belt and come right back to get valves and gaskets. Daewoo timing belts must be replaced every 60,000 miles.
There is no room for error...... Zero clearance. If off one tooth it can and will bend valves. if you are one that just feels the need to get alittle dirty or just can't pay for the service, then get out your Haynes out and turn to .....Tune up, and look at replacing timming belt. Get a cam gear tool that locks them into place so as that they will not move when u have them lined up. make sure they are lined up with marks as said in book. then make sure crank as well as all marks are lined up acordingly. make sure belt marks are lined up with everything. i would reccomend using a volvo belt though cause it will have all the marks on it.However other company's make good quality belts also at a fraction of the price. So it is really up to you.
Good thing when doing timming belt is to also change out your timming belt tensioner. YES do this it will save you a engine in the long run. it is a moving part that will go bad, it will freeze up and snap timming belt. rip out teeth in thebelt and bend valves. So as a gen rule...When you change timming belt, Change belt tensioner at same time since you cant just change tensioner without changing or getting timming belt off. Remember to use your HAYNES. It is your friend and will save you money in the long run. Good luck... Hope this helps you.
Yes these codes are associated with the MAF Sensor. One can trip the others as well. I would try removing the MAF Sensor and cleaning it first (brake cleaner or contact cleaner), then if that doesnt work I'd chalk up the bucks for a new sensor.
