Re: [MBZ] New Heater Question was Re: Monovalve Static test out of the car?
Replace the foam - the new part has been improved so it's now rubber that won't rot so quickly. If that fails to solve the problem, swap in another PB ACC moduie.

Re: [MBZ] New Heater Question was Re: Monovalve Static test out of the car?
Failure to regulate a proper temperature is usually due to a rotted foam hose under the dash. Hardware store pipe insulation may be used to replace the rotted-out segment. On that system, the common failure points, in no particular order: 1) Torn monovalve diaphragm 2) Cracked solder joints inside the pushbutton unit. 3) Rotted foam hose going to the cabin temperature sensor. -- Jim ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
[MBZ] New Heater Question was Re: Monovalve Static test out of the car?
The heat in my 85 300D is difficult to regulate each time I start out. If I have the temp regulator set for anything other than all the way cold it blows major heat until I rotate the regulator all the way to cold, then wait for it to blow cold. After doing that I can regulate temp pretty well although it seems like the temp is set way to cold on the regulator. Any thoughts? Thanks, Mike p.s. Sold the 84 300D vegoil vehicle and all equipment for $500.00. Original price of vehicle was also $500.00. It was not running well, very low power. The rear cylinder compression was low. After testing, I determined it was not a valve issue. Oil in the cylinder during the recheck and compression returned. So glad to have room in the garage again! After all expenses I think I saved over $5000.00 over the life of the vegoil project. Michael E.
