W205 Today I tackled this as it would appear I had coolant leaking from underneath the car and warning on dashboard and when you looked around by the fuel filter housing and the egr cooler there was a build up clearly showing however I've fitted the new redesigned model can only fit two bolts as isn't slots for all three. However I took it for a test drive after refilling with coolant and now it appears the dashboard warning has came back on yet again? Any ideas or suggestions to what's happening?
That's correct only 2 bolts needed as they mount it too the head. Maybe do a pressure test and make sure there isn't a leak else where? Only other thing is the egr cooler that side or you just have an air lock and needs topping up
Hello there mate great video 👍🏼 ! I have the same engine and it tells me to top up coolant every around 2 months ! You reckon this could be the issue ? Thanks in advance
Sorry for late reply I never got notification. I use a dab of silicone grease. Never use silicone sealant on a rubber seal defeats the idea of the rubber being the seal.
