A member called today with questions about a 1963 Buick Riviera. The car was recently purchased by one of his regular customers; it’s not a museum piece, just a nice Sunday driver that looks great. While the previous owner seems to have done a nice job reconditioning the car cosmetically, mechanically it has apparently been defiled by one or more shade-tree mechanics. The heater doesn’t work, and the fact that the heater core is a modern replacement part that is already clogged makes it obvious that the cooling system has been neglected for quite some time. Not so the air conditioner: it’s a factory-installed system that was converted to R-134a. The throttling suction valve was modified for the conversion as per normal, but some of the lines are joined with hose clamps. That’s probably why he recovered only one pound of refrigerant from the A/C system. Fortunately, the customer wants things fixed right, and the correct parts are available.
Our friend’s problem is lack of service information. He has the Chilton manual for that year, but the only information shown under heater core R&R is an exploded view of the heating system, no step-by-step instructions. Not that he couldn’t figure it out; he’s a pro who’s been in business a long time. He has also earned a reputation as the right place to take a car like this. But the car has already been molested and there’s a budget for the total job. His long-time customer understands that labor will be charged as time spent, not book time (3.4). So, if anyone out there knows how to do the job or knows where to find a heater core R&R procedure on a 1963 Buick Riviera, contact me right away at email@example.com and I’ll pass it on.

When having your mobile A/C system professionally serviced, insist on proper repair procedures and quality replacement parts. Insist on recovery and recycling so that refrigerant can be reused and not released into the atmosphere.
