DeliveryValve wins! That car must have had heat issues for a long time.:D

I think partially damaged or completely shredded doesn't matter. I had essentially no heat in my car even with the slightly ripped one.

I don't have a picture but I bought 3 new valve repair kits (like to have spares) and they were bad out of the box. Nothing visible. I found you may need to test these (they were not Bosch) when new by:
1. Put them in place in the top coil portion of the valve 2. Apply 12 V 3. Valve should extend and stay extended The bad ones either would not extend or they would stutter in and out under constant 12V. I was able to dissasemble and use the rubber portions. |
If you buy cheap aftermarket stuff (non-bosch) thats to be expected. Were they cheapo made in china or something? Shame! Shame!

If it's primarily a "seal" failure that keeps them from working properly-- are the seals available, somewhere separately?? My valve "functions" but if you really nail the accelerator (like getting on the expressway) the heat goes away, so it CAN function... I'm assuming the seals have hardened or cracked, and the higher output from the water pump on hard acceleration essentially creates "blowby.."
If the seals are out there-- is there a "reason" to replace the entire valve assembly, if it's working?? AJ RN |
where is the monovalve located on a 560SEL 1991?
