Denso seems to be the general consensus elsewhere, but I prefer your expert opinions

Also, where are the most common ports for leakage? I'm figuring 1-1.5 G's on the repair; is that about right?

Also, my viscous fan clutch is shot and spins all the time, as well as my Aux fan not spinning at all. Interestingly, my engine does NOT overheat. What brand clutch should I procure for the R&R? Also, the FSM doesn't seem to have a procedure, is it the same as a GM? I've done of those before in a truck a few summers ago.

Thanks a lot guys,

Carlen

Just thought I'd throw this in. Was chasing a leak in my '91 420 SEL. Thought it was the dreaded expansion valve as there was green dye on the lower hose ends, and the carpet, and lower dash cover. Replaced the expansion valve (not really that bad) had the system juiced up. Found dye on the small lower expansion valve hose. Turned out the hose from the filter/drier to the expansion valve had two tiny pin hole leaks on the rubber part from the false firewall into the cabin. Since it runs down hill it collected right at the metal fitting at the EV. Anyway if you think the expansion valve is leaking, you might want to check the hoses first.
