My pleasure - this place has contributed to me in so many ways I can't even count.

Reading the whole thread again, some other/additional thoughts:

• The QH seems to be the "Early M30" style with the larger/35mm block-off plate - so from the sound of the thread works, but with "faster warm-up" (in quotes because I'm not entirely sure what that means or the impact of it)

• Obviously the Vernet isn't an "exact visual match" - I might be misremembering his words, but it is pretty clearly dimensionally similar or the same, albeit with a very different design and construction.

• The Vernet is working fine for me

• The Calorstat/Vernet TH1528.80J can be found on ebay fairly easily for under $30 delivered, but my searches on the part number all show up from European sites.

• My shop was able to have it delivered, so I don't think they're hard to get (possibly enabled by the next point)

• Note that ebay listing also states it's for a mid-late 80's Jeep Cherokee. I'm not sure if that's a useful tangent or not, but it's an amusing one

• I was able to find the TH1528.80J on CarID for $15 (before shipping)

I hope that adds some clarity and is useful to someone - nothing sucks more than not being able to drive your car because of something small like this. In this case, that small something also keeps your motor from overheating, so...

Cheers!

Ahh I have just order 2 thermostat from Pelican so the chances are they are very likely won't fit?

Hey. So what part do I get? I have 4 thermostats and none fit. Any good options?

@e24mpwr. Thanks a great comparison photo.

I might suggest contacting the folks at La Jolla Independent for help/parts.

See the Vernet in my post on Page 1 - fits and working just fine in my M88

FWIW I went through 3 'other brand' thermostats that didn't fit until I tried the Calorstat OEM 80C Thermostat - S38 Engine - E28 M5 & E24 M6 from Bimmerworld which appers to be an exact duplicate of my OEM S38 stat. I also ordered one from Rockauto listed as Motorad but received the identical Calorstat / Vernet part.

Do you mean the one from Bimmerworld had the teepee/tent look like the OE or just measured/fit like the OEM S38? (in other words, are both of the tstats you mention the Calorstat/Vernet part?)

They were identical in appearance (including the te-pee) and dimensions as far as I could tell.

Can you post their part number? The one I found from Calorstat looks very different (dome vs. teepee), but works fine. I'd love to see one that mirrors OEM...
