Project KP30: M3 This – Thermostat Housing

Well, the old housing was well and truly warped beyond ever standing any chance of getting it to seal.  I gave it 4 goes, used sealant, hand flatted it on a machined surface, checked it with engineering blue…I was ready to throw it in the bin.  So I did.  Luckily, I had another 90 degree housing off a later KP and, with a little modification and a new top hose, it fitted pretty well.  I think it looks neater and it takes the load of the rocking engine better too.  I don’t really care about that though…I’m just glad it holds coolant!

They Make Joy. I Make Steam.

BMW spent millions developing the E46 M3.  I threw a slightly bigger, tuned engine into a 34-year-old shopping car.   As a result, when racing said M3 though a series of roundabouts, all my coolant fell out.

Turns out the thermostat housing is warped from, I’m guessing, attempts to weld it, so it blew the gasket at about 7000rpm in 3rd.  It sprayed coolant all over the screen and left a pretty impressive trail of steam behind me; the main point is I only lost a car length on him before slinking off down a side road to boil in shame…so technically I won*
