Title: Cleanliness is close to godliness
Post by: Marks DTM Calib on 24 March 2010, 09:34:22

....and removes the need to take engines apart again!

Changed a thermostat for a member on here last night as it was stuck open.

Now this particular power plant has a checkered history as mentioned on a previous thread as the engine should be a 2.6 but, it certainly has pre 98 2.5 heads fitted!

Anyway, having removed the offending stat, it became quite clear why the stat was faulty.

You can see a huge length of sealant stuck in the stat........

So, let this be a lesson to all.....excessive use of sealant is not good and cleanliness is essential!

i just used a small dab of grease on the o-ring when I did the stat on the 3.0, that sealant almost looks like black cam cover sealant?

I suspect it was cam cover sealent.....the trick with sealent is to just use a wipe of the stuff.....not so much that it ouzes out when compressed into some huge additional O ring!

wonder if they thought it needed it, the o-ring i got with our kit was quite thin, and did not fully fit depth / width of the grove on the stat, its been watertight though  :-/

A shame, especially as it looked like a decent stat.
So, inappropriate use of (excessive) sealant and a need to do the whole job again, plus stat and a/freeze ...
Still, not sure why 'that' bolt got it's name.

I reckon an engine is only clean enough to reassemble if you'd be confident licking the bits.
