Apologies if this has been discussed before[it more than likely has but I'm not clever enough to find it]today I enquired about the cost of a new thermostat only to be told that my car was built at a point where a change was made between just a 'stat  and a 'stat that's integral with the housing.Is this likely to be correct or am I being mis-informed as to there being two types?Car is a 3.0L V6 Elite registered on a W in 2000 and is a F/L model.

I would go with the integral one

At least that way you're not stuck if the housing cracks or gets damaged in the course of removing the transfer pipe or thermostat core

[BazaJT]

Ah,so if I buy integral type but my car has the other type then they're interchangeable,yes?

[05omegav6]

Someone wiser will be along to confirm, but I would be very surprised if there not interchangeable

[davieboy0312]

yea the 3.0 on a W the thermostat is interchangeable defo mate

I know that most Omega thermostats are Integral type (even the Omega A) ... also it will have more ensured operation .. but the important thing is to buy new original GM part with suitable operating temperature.

[davieboy0312]

the thermostat pushes into the thermostat housing so is integral to the housing but you can remove it from the housing

[05omegav6]

Given the risk of cracking the housing on removal, you would be daft to by the thermostat core on its own

[davieboy0312]

definitely I agree but there are some people who would go for the cheapest option

crack a few of them in my time and the long pipe coming off it. if you can buy the complete housing

One of theses... about £36 delivered

Rest of it from VX, total is about £50-55 in bits...  Genuine stats retail for around £78 here but transfer pipe and O rings are cheap enough, £14 iirc

Sure it retails here for £12-13 + vat

[BazaJT]

Been quoted £24 inc.vat for integral type.So if I get that then I'm also wise to buy a thermostat pipe and if not included some "o"rings,is that right?Just want to be sure I have everything necessary to hand before I go in to the job.

Exactly the p/n for the transfer pipe is in my last link... pretty certain that it includes the O rings

[BazaJT]

O.k.,thanks for that.I'd have just gone ahead and bought thermostat and not known to buy pipe too.Ain't this forum wonderful?!!!!
