does anyone know if there is guide for changing the stat on a 2.6.
(oh,its a little urgent, thanks for looking)
-
Don't think there is mate.
-
Next Question, is a low coolant temp affecting my MPG by much. The problem is deffo the thermostat and not just the guage. Stop start driving the guage eventually goes to around the 90 mark but motorway driving it only goes to 75-80.
Edit: Where is the thermostat ::)

Unfortunately its in the V behind the cambelt.
Follow the cam cover gasket guide to strip the plenum etc off (note yours is drive by wire so slightly different) and you will see it.
Then pop the power steering reservoir out of its bracket to obtain access to the Bstard bolt which holds the bridge pipe in place. You haev to remove the bridge pipe to get the stat out adn you should do this before un-bolting the stas.
You will need new O rings for the bridge pipe but, be warned, we broke one at teh cambelt party and given they are only about a tenner, its possibly worth getting a new pipe to be on the safe side!

What you need to do, Mr DTM, is a nice guide. Now, I could present a nice car for you to use for this ::) ;D

This sounds like a job for a seasoned spanner merchant.
How much is this gonna cot at the stealers?

It does mine, about 3 ish mpg on a run, 5 or so if it's all local stuff. I know I need to do this, but I need to clear a bit of space in the garage by putting my Stag back together so I can get the Omega in. A guide would be great!

Hotel21 (Broocie) did this job on Kate's car at the cambelt party. When you have taken off the plenum etc. to expose the stat. the metal pipe running from it to the radiator hose runs through a tunnel under the cam housing, and is tough to get at. You have to pull this pipe out of its joint on the side of the stat. towards the near side, and if the joint is seized it's almost impossible to get enough purchase because of the confined space. At Shifnal it resisted brute force and every other form of persuasion and had to be smashed with a hammer and chisel, removed in pieces and discarded for a 2nd hand replacement.
I didn't see the re-assembly being done, but the end result, (the thermostat wasn't present in Kate's car, by the way), was engine temp. back to normal, and improved mpg and cabin heat.
A main dealer would no doubt charge a fortune so if you can do it yourself you'd get a better result at cheaper cost.

Think it's quoted at or around 2 hours labour... £75-85/hour?

Having broken a transfer pipe previously, when I did my 2.6 I used a small die grinder to cut a groove in the thermostat socket.
A screwdriver twisted in the groove cracked away enough release the transfer pipe.
Be careful not to grind into the transfer pipe, the o rings will need to be changed.
That's why it takes half a day or so.

Are you saying you scrapped the housing after this?

That's how it appears to me Bill :D
Having said that, a new stat comes already in the housing.
And if the worst happens, a transfer pipe is only about £12 retail
I hope the 2.0 Estate is running well, after the cambelt change? :)

Hi James,
Don't want to hi-jack this thread, but must repeat my thanks to you for doing my cambelt. She is running beautifully, but I can't decide whether to sell it on or crack on with sorting oil leak, blowing rear box, broken check straps, etc., just for the experience and the fun.
Cheers,
Bill.

No mine would be much more photogenic ;D :y

The housing is definitely scrap, but it is replaced with the thermostat so the old one would go in the bin anyway.
It's not the cost of the pipe, it's the 20 mile trip with no car to find none in stock and then a two day wait and another 20 mile trip with no..............
-
you need to make sure you have the right replacement stat unit too. There are different thickness base plates which need different length bolts...
-
It's definitely worth getting your stat sorted. I was so sick of driving round freezing cold. I am sure I saw icicles hanging off the gear stick a couple of weeks ago! ;D
The mig drives better as well but the mpg hasn't improved much. I think I do about 20 gallons to the mile! ;D
It was a bit scarey seeing my mig in bits! :o
