OM612 engine (5-cyl diesel) - 6 hours to replace thermostat?

[drivencrazy]

Hi
An indie has quoted me 6 hours to replace the thermostat on an OM612 engine (5 cylinder diesel). Is this reasonable?
Thanks in advance for any replies.

No

I've read it's a chew on with parts to remove, but do able by a diyer . Fuel rails and manifolds can be left in situ if the stat is waggled about enough.

Yeah, I changed one in mine W210. Long time ago, but If I remember right, something needed to loosen a bit (fuel line maybe...)... and one thermostat housing bolt is in very dire place but flex or jointed shaft and bit tools will do the job. I would say 1hr diyer, 30 min pro.

Thank you for the replies.

The outcome was that the indie charged me for 2.5 hours for changing the thermostat, which is more time than suggested above but less than the 6 hours originally quoted. The engine is heating up quickly now - a great improvement.
Thanks for all the replies above.
