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

****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)

***This is just my personal walkthrough, shouldnt be taken as professional advice or way of repair***
After a bit of frustration, i found it lol
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
