how do I replace the AC expansion valve on a Mercedes C280 sedan. location and procedure
My 82 Mercedes continues to run after I turn it off with the key. I was told I needed to replace one or both of the shut off valve. What is the procedure to do that?
You can remove the EGR valve from your 1965 Mercedes ML 320 by removing the valve retaining screws. Remove the vacuum line from the Bell. Reverse the process to install the new valve.
Remove the Air cleaner completely and you will see the Cold Start Valve underneath with the wiring plug attached to it. You can instantly recognize this valve from the Allen Key screws that bolt it on to the manifold. John T
Make sure the cold start valve is working properly and not seized up.
You need to clean (or replace - $200) the idle air valve.
It's better to go ahead and replace it.
The cold start valve could be checked by scraping the feed wires for a 12v input when the engine is cold. Use a tester for this. Put on the key to start for a half second. If there's no 12 v in the wires, remove the cold start valve and position it onto a container of gas. Aim a jumper wire from the battery positive line but do not touch it yet to the exposed wires leading to the valve and have somebody crank the engine for half a second, at the same time, touching the wire to the battery. Gas should squirt out. If no gas comes out, the coil is bad. Replace the valve. If gas comes out, the coil of the valve is good, but the thermo-sensor is bad. Replace the thermo sensor. It is normally found screwed into the engine block and the feed wires of the valve comes from it. -rogue1man@yahoo.com
You need to replace the EGR valve. Make sure to replace the plugs too after that.
