Eric you've made a mistake.

You've installed this on the wrong car, it should be on my SD.

Thanks for the photos. It seems that the best way to mount the oil cooler lines is the way Klima designed their bracket. I copied the bracket for my kit from another member (1980sd), not seeing Klima's design until now-

The problem I see with Klima's bracket is the mounting on the aluminum casting. The tabs are squared off, and seem to ride up on the casting (hard to explain). I made mine so it looks like two flat washers on the mounting surface. That way, the bolts tighten up all the way without any gap between the bracket and casting.

The updated OE one as found on the '85 MY and later cars. Should be fine with R12.

Wow, that is really nice. The anodized brackets look pro.

i'm always curious about how well these a/c retrofits perform. to do a "proper" r12 to r134 conversion, you really need to replace all of the hoses. all of them. r12 hoses are porous, the r134 will leak out right through them. replace them all with modern barrier hose. also most vehicles need a larger condenser, otherwise your vent temps on r134 will be noticeably higher than they were on r12. i'm not at all familiar with the sd's a/c system, so it possible that it has a large enough condenser to give satisfactory performance, being that it is a larger car. on some smaller cars, you even need to upgrade the evaporator to a larger one to get any sort of decent performance out of it. r134 simply isn't as efficient at cooling as r12 was. good luck with the project.

Late '84 built W126 cars were updated with a split tube and fin condenser which over doubles the surface area the refrigerant sees. Also sometime around then the water pump pulley size was reduced resulting in better cooling via faster fan speed and coolant flow at low speed.
Typically these cars will cool very well with R12, marginal with R134.

I have a picture of frost on the suction side of my R4 taken yesterday with 106f ambient. System is running R134, PAG150. Unfortunately, once heat soaked in rush hour traffic, vent temps start to rise. Comfortable but, could be better.

Where in the world did I say I was converting to 134A?



If that was the case, I would be installing a PF condenser at the minimum and probably a modern evap core. Hoses would be the least of my concern.
