Is the lift pump on a Mercedes 190D?
My 190D had the thermostat bypassed when I bought it. The line can go right to the lift pump with no issues. BTW, all OM601 OM602 OM603 engines have that shut off lever. If you have a manual you can dump the clutch on a high gear, but that’s not a good method to use at all.
Is there a way to stop the run away in a Mercedes 190D?
For turbocharged 602 and 603 engines, the only way to stop the run-away is to choke the air off at the turbo inlet or dump the clutch on a manual car. You must take away air, fuel, or heat to stall a diesel engine.
How does a Mercedes 190D fuel tank work?
I did the same thing to my sister’s 190D as you did with the fuel thermostat. Here in southern Arizona we don’t get cold enough for that thermostat to do any real good. The anti-gel additives do their job well and as long as the engine starts, the fuel in the tank will warm up quickly due to the hot returned fuel.
How to fix a leak on a Mercedes Benz W210?
This is most easily done by using a few dabs of gasket adhesive every couple of inches in the channels around the perimeter of the valve cover and also the spark plug holes. One problem with the M104 is that corrosion develops under the coating on both the inside and outside of the valve cover.
Why does my Mercedes Benz have a vacuum leak?
This is due to the extra unmetered air flowing through the oil filler port. If there is no change in the vehicle’s idle, then you probably have a vacuum leak somewhere in the system. Don’t forget to check places where vacuum leaks may not be as obvious, such as the oil filler cap, the dipstick and also the valve cover.
Why is my Mercedes Benz W210 running rough?
Many times, a lean running condition can be traced back to a cracked or torn boot in the system. A good quick way to check the overall health of the system is to take the oil filler cap off with the engine running. If the system is in good shape, the idle of the engine should drop and the car will run rougher.
What do I need to fix my W210 vacuum leak?
Around the perimeter of the valve cover, you’ll want to replace the cover gasket as well as the 6 grommets that get sandwiched between the cylinder head and the valve cover. Both the valve cover gasket and spark plug grommets need to be glued into place.
