Mi16 Thermostat Housing - Does It Have A Gasket?

[Jonmurgie 2]

Got a little coolant leak around the plastic thermostat housing on my Mi... is there a gasket there at all? I have another housing that I was going to clean up and fit in the other one's place but not sure if there's anything else that's supposed to go in there as well?

 

Cheers

There are two rather large o-ring rubbergaskets supposed to be placed on both sides of the thermostat.

The plastic half that's fitted with two 13mm bolts should seat against the outer o-ring on the thermostat.

Ah right, so perhaps a new thermostat would be best, as I guess these come with the O-rings?

Not sure, but I don't think they usually do.

The O-rings are dead cheap anyway. Even my local motorfactors have them in stock for approx 1£ for the two of them. And usually things seem to be less than half the price in UK, so..

Ah ok... well I'll pull it all apart and see what the score is!

 

Thanks

I tend to use the o-rings with silicone sealant around the housing. I use the metal housing as I alawys had sealing probelsm with the plastic ones; they seem to flex very easily.

Yeah, I only have plastic ones availalbe... the one that's on the car and the one from my other Mi engine! If this one leaks a little as well then I'll source a metal one

There are 2 types of housing, One for the 2 'O' rings and the other for a one piece seal which clips over the stat, The latter is quite rare thou

Jon, I forgot that I used the alloy housing off the 1.9 8v engine which just has one large top hose outlet; the plastic Mi has an extra on I htink?
