I took off the T-stat housing to replace it on the 240D and the water pump housing on the 300TD. Go the T-stat housing route. MUCH easier....but make sure you have the gasket in hand.

Good luck!

So, when the t-stat housing comes off, I don't quite get how to remove/install this hose. How can you get the hose in there w/o lifting or lowering one side of the set up? If the hose is between two parts, how can it be installed w/o cracking or bending the new hose?

If all the heads break off the bolts the cover should be able to be removed.....

Believe me, I hear you...I'm just telling you what happened to me. I could not understand the physics behind what was keeping the cover on. I pried, tapped with a hammer, pulled, and lightly twisted...nothing. The shafts of each of the bolts was still sticking out the front - I tried, in vain, to twist them out with vice grips, and the screws just shredded and disintegrated right before my eyes. It was insane.

Happy Labor Day!

The T-stat housing kinda has 3 sides: 1: There is the back of the part that you opened up to change the T-stat. 2: There is a side that goes straight down to the little connector piece. 3: There is the flat side that connects to the engine block. There is a bracket that supports the A/C low pressure hose, you remove the 2 bolts to the block on that bracket (the AC hose will kinda hang there), and pop the housing off the block. The 3rd side goes down to the connector, and the piece of radiator hose connects to the water pump housing below.
Replace the hose and clamp it in place (TIGHT).
Scrape the gasket off the block and clean up the housing, then replace the gasket. (I used gasket sealant on the block side of the gasket then bolted the housing and bracket back in place).

That's it!
