Thermostat OEM Audi or MotoRad

Been running the 80 for a month or so. It works great. Car and Temps run flawlessly. Only difference is my average warmed up Temps are 85c. Used to be 95c

I finally got around to installing a new thermostat/o-ring/housing and coolant reservoir/cap yesterday. When removing the thermostat, I noticed that the bottom bolt was VERY loose... I had done the thermostat without housing about a year ago now, had never leaked coolant before... My best guess is that I just didn't torque it enough and it slowly loosened, but only when cold (just a guess, but would help explain why no drips when car was running on ramps) and in small enough amounts that I did not notice a puddle on the ground.

I had a 96 and have done that job twice, make sure replace the thermostat otherwise it's a do-over several months later because you tried to save $20. Been there etc!! Change the belt, tensioner, water pump and thermostat.

Just not Motorad--unless you want to replace it again in 6 months

MotoRad thermostat. Lasted less than 6 months.

never trust an aftermarket thermostat! Especially if it has MOTORAD stamped on it.

Oreillys used to have Motorad thermostats that were 2-5$. Then they started carrying Murray, which are double the price. Guess what's in the box? Motorad. Cheap crap for a premium price.

The current plastic thermostat looks a little more beefy, but is still shatty plastic. They're commonly failing at 30-55k miles in the stuck closed position, instant overheat.
