Most responsive S5 cloolant gauge ever? The vert's endless problems.

There are many "thermowax" devices on the engine...

There is the front eccentric thermowax pellet which allows oil to flow through the eccentric shaft (and rotors).
There's the thermowax on the throttle body which controls the cold-start fast idle.
There's the thermowax pellet in the oil cooler which allows oil to bypass the oil cooler core.

When talking about COOLANT, there's only one thermowax on the throttle body.

Update on the thread: I got replacement hoses, thermostat, and radiator cap, as well as really good Mercedes coolant, it's all ready to put in, except for the fact that I cant quite get to the block drain plug to drain the rest of the coolant out... I think I will need to take out the AC compressor to make the job easier.

My radiator had quite a bit of CRAP logged in there. I sprayed a TON of degreaser, follwed by garden hose, an then power washer. The radiator is pretty much see through right now.

Look at your drivers side engine mount where it bolts to the block. Notice the 3 studs/nuts? Notice the long hex "nut"? Undo the hex nut and you'll drain the coolant out of the block. IIRC that drain is lower then the one behind the P/S pump bracket anyways.
