Cadillac Seville / Cadillac Eldorado Forum Discussion, Post new radiator install, temp issues in Past Cadillac Vehicle Discussion; Got it booked in, to have a coolant system flush, explained the issue and history, they said they hook it ...
Definitely says 15 on the current cap on the car, I've never changed the cap, and the previous owner (friend of the family, maintains most of vehicles himself), says he has never changed it, so a mystery. Up to the point I changed the rad out, the 15 psi cap seems to have worked fine, as did the cooling system, even in OK 100F summers the temp gauge hardly ever went pass the 12 mark.
Also, the RC87 cap looks identical to the current one, the RC98 looks different, not that looks mean much, just saying...

Yes it is. A flush is simply running fresh water through the system. A power flush does it with a flush gun under pressure. Based on everything you said, I think I would lean towards a power flush, but that's just me.
you want it flushed - not just a regular drain and fill -
I am a former shop manager and let me give you one piece of advice.
WATCH them hook the machine up and do the flush.
It does not matter if you know what they are doing or not, just be sure they hook the machine up.
I have had mechanics working for me in the past who did a drain and flush (against my orders) because they thought they could get away with it due to the fact that they were lazy and didnt want to hook the machine up.
