OM606 Revisited for Defender

Long shot since this thread seems to have died - but for those that have put a Mercedes engine in their Defender, how did you connect the thermostat so that the temp reads on the instrument/gauge cluster? Currently I have a digital readout mounted to the engine side of the bulkhead (mechanic installed) - which really does me no good while behind the wheel.

Adapter for the LR part is what’s running on my OM swap. I forget what the sizes are exactly.

Has anyone with on OM606 figured a way to read oil pressure? Or found an oil pressure sending unit that works on the 606?

I used this on the oil cooler line. I am using the madman system for monitoring oil pressure. Depending on what mounts you are using you may have room to come directly off of the oil filter housing as well. I am LHD and using DPUK mounts, so it's pretty tight in that area.

Thanks for the tip. Mine is a RHD and in peeking down there, I see I might have some room to play with - though it does look tight. I'll take off the manifold later to get a closer look. So as a follow up question - any particular kit from Madman that you used? https://shopusa.madmandevelopments.com/collections/oil-pressure-measurement-kits

Second, did you run this to an oil pressure gauge in the dash, or just affix a pressure gauge right to it? I'm hoping to use a gauge in the dash.

What mounts are you using? The 606 swap is easier on RHD for sure.

My truck was originally a 200tdi I was using Madman's dash gauge before the swap so I just moved the pressure sensor over to the OM606.

Also the guys a DieselPumpUK have a nifty oil pressure sending adapter that makes installation of any standard or VDO gauge a breeze. Can T off that for both pressure and temp.

I just finished redoing my fuel system. I finally gave up chasing air, even with brand new pipes.
Are you saying things are good now? You fist tried new pipes but that didn’t work? What do you think was the issue?
