Thermostat on my 04 V8 went and just got the bad news...$800. Apparently its over 7hours of "book" labor. Having it done at an indie.

Hmm, I think one of these guys told me once it's easier on an 04 than an 08 due to VW changing the engine? I'm not sure. But I hope you replaced the whole system! And I hope it'll last for a long time!

Ever find out if the 2004 is easier? My 04 is currently on the hoist. I’m hoping for an easy job for my indie mechanic. Easy for him=less money leaving me!

Which model do you have? It won't be the R5 2.5 Tdi you list since that was never sent to the US!

Looking into doing this on my 2004 3.2 v6 I can not find any traces in ELSAWin of a 3.2 engine sold by VW in 2008 like the OP states. VW moved to a 3.6 before 2008. Both 3.2 and 3.6 thermostat replacement look easy to do as per the instructions on ELSA. I will make a 3.2 thread when I do mine.

So instructions for the 3.2 (2004). No engine dropping.

And the 3.6 (2008). No engine dropping.

Hello,

The dealer has informed us that we have a seeping thermostat housing. I have searched everywhere for a video to no avail. We have a 2013 VW Touareg V6 gas vehicle. Does anybody have a set of directions to get to the housing? From looking at the vehicle, it seems as though it is in the back of the motor. I tried crawling under it without removing any protective covers, but can't see it from there. Also, cannot see it from the top of the motor without removing things. Ordered and received all related parts. Any guidance available would be greatly appreciated.

On the 3.6 the housing is easy to replace. Check this thread for some pics of the setup.

Upgrading the 3.2 thermostat housing to a 3.6 one !

I started thinking about modding the thermostat housing on my V6 3.2 to make the thermostat easily accessible and serviceable and also make it bullet proof by upgrading it to a cast aluminum housing when I had an idea: My idea was to re-locate the thermostat housing by using a custom housing and...

Removing the intake manifold will make things easier.

Thank you. The pics really help. Is it worth the time to remove the intake manifold or is it doable without removal?

If you have to remove the whole housing you better remove the intake manifold but you can try without. And it depends where the leak is. Can you pinpoint the leak on the pics in my thread? It’s probably just a bad o-ring. The 3.6 has a one piece housing and crackpipe (pipe going to the water pump). You need to determine the exact location of the leak.

Yeah, it looks pretty tight in there. Are there any other gaskets that I should replace? I will get the intake manifold gaskets on the way, but as you know, sometimes it is easiest to replace other stuff while in there.

Thanks!

If you’re not cleaning the throttlebody then you need the intake manifold gasket only. The o-rings will come with the housing kit. Just make sure you get everything. If you want to go bullet proof you can get the billet aluminum version and be done with the plastic stuff. But the plastic does last a long time too.

Aluminum Thermostat Housing

Common point of failure or leaking for the cooling system. Features a superior aluminum construction over the factory plastic unit.

Had my cracked thermostat housing changed by my independent mechanic today on my 05 V6. Part was $163.00 and labor $510.00. Did not have to drop the engine.

Service trany at same time $124.00 parts $76.00 fluid $187 labor.

ABS brake pump also bad bit that part is 1400.00 plus a bunch of labor. Vehicle stops just fine as is.

Instrument speaker is also out but can't change that because the ABS will make it beep constantly.

Also headlights are too expensive to replace so I just use high beams.

Good thing this is just my fishing vehicle!

Hello, do you have any idea how he was able to access it ?

Have a 2004 v-8 and the dealer replaced the t-stat yesterday. The vehicle was running hot, fluctuating from 200 (the normal temp gauge reading) up to 220 and 230 degrees and back down for a couple of days last week. If I would just turn the vehicle off and let it cool down for a couple minutes it would go back to 200 degrees. The problem got progressively worse over a period of a couple days. Obviously I knew it must have been a t-stat or fan issue. Turned out to be the t-stat. Parts and labor under $800 bucks. I was very relieved that it was not more. Drove the vehicle about 60 miles today after picking it up this morning. Seems to be running well today and the temp is consistent at 200 degrees. 118k miles.
