Title: How do I fix this? Heat Feeler Housing
Post by: karmannghia60 on October 10, 2008, 20:25:48

Hello
'69 280SL RHD. Developed a leak couple of days ago. Found a burst hose which is coming out of this thing below. Excuse my ignorance, don't know what it is but looks like a thermostat. After taking the hose off, I found the casing is rusted. What do I do? Is it fixable?

Hello,

This is the "heat feeler" housing for the WRD (warm running device) on the injection pump. This is typical corrosion damage caused from no anti-freeze or old anti-freeze. Besides eating away steel parts, engine aluminum castings can also be damaged. Coolant turns acidic after a few years. Change it every two or three years. Find someone with a scrap injection pump and you probably will find a good used one. Anything is fixable, but replacing it with a good used one is most likely the least expensive and easiest way. I do not know if these are available new by themselves?

It doesn't have a unique MB part number so I don't think it is available from MB...

I can't remember ever seeing one this bad. I've seen them plug up with silty looking mud but rarely ever so rusted.
I should have one in my collection.

I would suspect electrolysis as a possible culprit. Chech this site and/or google engine electrolysis.  http://www.radiatorreporter.com/electrol.html   Bad engine ground, etc. can cause it. The link tells how to check for it, we should all check the engines on our cars as iron and aluminum together are great places for this to occur.

Contact John Green in Canberra. He had some made out of stainless steel.

A local friend bought one and it looked very good.
It wasn't too expensive.
