Thermostat too big
Hard to believe, but the thermostat I fitted a couple of months ago didn't *quite* fit into the recess in the housing ..not too tall or deep, too wide.
Yes, too wide by a hair or two.
I know I should have attended to it in a better way back then because when I assembled and refilled the system the housing leaked coolant.
I was doing the service in my brother's driveway in Seattle (no excuse really) so I needed a get-me-home fix. I plumped for cutting and fitting a extra gasket with a smear of gipe just for good measure. Refilled the system again and checked for a leak, all good, so drove back to Vancouver Island.
Pretty much put it out of mind until last week I got the low coolant light on the dash ..wasn't that low, (about a pint and a half) but it was down enough to trigger the light. After filling the header tank up, I had a look around for hose problems, stat housing issues etc and didn't find anything obvious (although the car was already warmed up and I suppose any dribbles had evaporated).
Anyway, I checked again this morning and found traces of coolant under the stat housing ...so obviously my 'extra' gasket idea hadn't worked. Today, I'm going to take the stat out and file the circumference so it DOES fit into the recess in the housing ...damn aftermarket parts!! grrrrr ....
Will report back!

I’m planning on replacing mine too.
I did buy a failsafe Motorad, 192 degrees. I believe the one I have installed could be as low as 176 or 180 degrees.
I’d imagine that would effect heater performance, wouldn’t it?
From my research, the factory EBC3621 stat is an 88 degree C thermostat, or 190 degrees F.
I’ve never had one that didn’t fit tho. I have had ones without jiggle pins or bleed holes, however.

Red face here guys ...when I took out the stat (made in england BTW) I realized I had put the big o-ring on the wrong (block side) of the stat, no wonder it leaked and the stat couldn't seat ...no wonder I had a hard time with it! Nothing wrong with stat, just my brainbox ...
What a goof!
All fixed now.though
carry on
