MINI thermostat replacement

So the new car was giving us some troubles. A little bit of coolant leakage now and then resulted in a sloshing sound coming from the heater core behind the dash. Coolant leaks out, some air gets in, suddenly you have some sloshing when you rev the engine. No big deal…unless you’ve lost so much coolant that you end up with say, a warped head gasket. My old college ride GMC S-15 had these exact symptoms, and sadly, the above diagnosis. $600 lost.

As was the case with the Jimmy, I first assumed the coolant overflow tank was leaking (a common first generation MINI Cooper fail point until it was updated mid-run). Not so. Turns out the MINI R50/R53 thermostat housing is somewhat notorious for leaking. It’s plastic, unsurprisingly.

Update what now?

Good god, almost a year since an update. Well, rest assured there has been some work done on various vehicles, I even have some pictures. A third brake light on the Verona car (Uber) along with a new parcel shelf. The turkis car slowly moves towards paint. Bondo dust is imminent.

More to come, I swear!
