Thermostat Replacement - Use OEM?

[zak99b5]

I bought the redesigned plastic throat 180° OE motorcraft t stat and a gallon jug of coolant. Took me at most an hour to swap it out and refill the degas bottle. And while I’m an experienced DIYer, it’s almost all on VWs (Volkswagen—turning owners into mechanics since 1958). I’d done basically nothing to the expy before, mechanically speaking.

$1300 lol. I spent at most $60 in parts & supplies.

I went with the 160deg one because our aux fan was running on high speed all the time. Dealer checked EVERYTHING and found no faults. Adjusted to the new operating temp with a tune. Tuning after just a thermostat is not necessary, but more better...
Problem fixed.

Never did a thermostat before. Cost me $50 and 2hrs.
