Two reasons, it's quite a bit cheaper over here than the BMW one and secondly it's quite a bit cheaper over here than the BMW one.... I personally wouldn't use a pattern thermostat either...

Why bother, I promise you will never revert to original if you do it, or just fit the 740 one.....

Actually the 740D t-stat is even more here because it needs to be ordered from over there. They never imported the 740d to the US. When I was researching it I was hoping to find it or an equivalent cheaper. Looks like its the mod for me too. |

That's an 88 deg one so should be fine, you can't change the stat itself in any of the BMW original stats, that's one appeal of the kit, it's a lot cheaper and then cheaper still if you need to change the stat...

Well I got a spare thermostat from a buddies garage, ripped out the guts, but then I remembered I had an old ELM327 scanner lying around somewhere, so plugged that in to see the coolant temp.

You're right, I went for a short drive at night, still 34C outside, didnt have the gizmo with me, but scrolled through the secret menu thing where you add the numbers and press left and right knobs etc etc, The car was showing coolant temp as 105C |

Ok since I had a spare thermostat, I said screw it, had already stripped out the guts, Some one earlier had put the fan on so tight no amount of whacking was opening it, never used the special too on, P38s or L322, A few blows and the fan comes out.

I've just done this mod go as part of my rebuild. I read somewhere yesterday that you have to Dremel out a notch in the housing for the bleed nipple, I didn't so hope I haven't messed up. Sure I would have noticed though as I was assembling it all.

I've left mine unplugged because when I took the original thermostat apart and took the heating element out I could see the copper of the wires in the remaining housing. My thinking was that when the ECU noticed me putting my foot down it would send signals to the heating element to heat up and as there was no heating element just coolant it might short something.
