Glyn,

That diagram you posted, would it happen to be for another engine (non 1.8L Supercharged?)

Mines was quite different than what is shown on that diagram...

Oops - That's the M111 diagram - I will try & find M271 - sorry Chris

That aside - for thermostats unless you live in the Arctic you need an 87 deg C thermostat - there have been many numbers - some start A000

That stat you got is right.

M271 CORRECT DIAGRAM



90 deg C Thermostat is P/N A2712000015 for very cold weather
87 deg C Thermostat P/N is A2712030375 for normal conditions

Sorry for the SNAFU - Benzben & I both posted the wrong diagram

Can any moderators combine this thread with my other thermostat thread and make it a DYI sticky and Thermostat part # info?

****UPDATE:

Its been two weeks as of today and my car has had NO check engine lights!

The car warms up a bit quicker than before (in about 3 minutes its half way warmed up and within 5 its fully warmed up!)

Thanks you guys for your time and input(s)

Just follow the upper radiator hose(towards the engine block) to get to the housing. Remove the two screws and the wire clamp with a flat screw driver. After getting those 3 things off, this is where most of the labor comes in, pull out (while wiggling the plastic thermostat housing up and down left and right), the plastic housing will come right off and you will have your thermostat showing. Install new THERMOSTAT (take note of which direction the little PIN is *mines was pointing upwards). To re-install, reverse the above steps. You're finished.

I only used a 8mm click thingy wrench/ratchet to remove the two longs bolts on the housing and the top little cover to get better access. That's all i needed. Everything cost me 28 dollars with tax doing it on your own. Time was 35 minutes (first time doing this, 2nd time should be no more than 10-15 mins with everything)

Just a FYI for you DIYourselfers!

For the DIYer I thought I'd point a tip:

1) The rounded o-ring goes around the thermostat housing and creates the seal between the housing and engine case (?) so coolant doesn't leak out...
2) while the flat/band o-ring fits on the end of the housing and creates the seal between thermostat itself and the thermostat housing.

I mixed them up and and have had a slow leak over the past few days so will have to a R/R to get it right.

Also, be careful using a tool to pry the thermostat housing out if it won't budge. A flathead screwdriver will easily chip off pieces of plastic

I just did this myself and wanted to add a few comments. If you use a ratchet for the job, you'll need a 3" extension. I was surprised to find the thermostat housing extends ~ 1.5" into the engine block. Make sure to pull the housing toward the grille while wiggling back and forth, up and down. I found Gentle prying with a flat screwdriver did help the removal.
