MKV Thermostat Replacement

I bought the replacement thermostat from my local VW dealer (it's the entire plastic housing, not just the thermostat), but I can't seem to find its location. I can't find any DIYs on the web for the 2006.5 GTI, only the MKIVs and other non 2.0Ts. Can anyone give any advice as to where the thermostat is located? A picture, of course, would be invaluable.

Thanks.

chad1230 - the only thing near my oil filter housing is what looks to be the auxiliary coolant pump, not the thermostat. it looks nothing like the part i got from vw, so i'm guessing that's the case.

eurocars - from a diagram i saw, it looks like it's not easily accessed. do you know if that's the case?

xcrazydx - have you swapped the termostat before? does anyone know how to access it, i.e. what needs to be removed/moved?

No, haven't heard any info as to its specific whereabouts. The local shop quoted me $170 just for labor, I already have the part. I was actually going to take my car there today, made the appointment and showed up - they were closed. So, now I'm revisiting the DIY route, but I still don't know where it is.

Its under the intake manifold passenger side. You need to remove the alternator to get to it.

So, just back from the VW dealer, they originally quoted me 1.4 hrs ($180) based on what alldata time estimate said. When I got there, the mechanic looked at it and said it's a 2.5-3hr job, because you have to (as mcpot just posted) remove the alternator and it's bear to get to. The dealer is going to do it for the $180 still, since that's what they originally quoted me.

Why are you replacing your thermostat? Getting to hot or not hot at all?

mcpot: getting cel for engine not heating up quickly enough. engine temp would drop way down when going downhill quickly. i think the tstat was just getting stuck open. no problems now. although, i also had the timing belt and water pump done while i was there since i was at 93k and never done. the shops i had quoted all thought it was either tstat or the sensor unit, most likely the tstat.

I have a problem with mine taking forever to warm up and I can't put my heat on anything above 2 our I can watch my gauge drop below normal and it starts blowing cold. Mine also drops when I coast down a hill. Need to find time to do the install myself maybe I'll make a diy when I do it to help everyone.

Bit of a thread bump, but I've had the issue of water temperature dropping when driving downhill, I've now changed the thermostat and the coolant sensor, but the problem is still there, not sure what to try next.

Driving downhill I would assume you are not on the gas thus the RPM's are down. Possible issue with circulation of the coolant? Air pocket maybe?

The coolant was changed with the temperature sensor, I'd assume that would resolve any circulation issues, right?

Temperature dropped by 20 degrees this morning from 90 to 70, which seems like a massive drop to me.

I would log with the vag com and see what values come up. Also there might be some underlying codes in the system that can help you figure out what's going on.

Scanned for fault codes and there were none. I'm waiting to get a vag com cable to log coolant temperatures, but the problem seems to be getting worse. The temperature dropped to almost 60 degrees this morning and is struggling to get to 90 for any sustained period of time.
