Funny, I was working on them as brand new cars and in Texas and some parts of California we had plenty of problems with overheating QV.s. Factory was involved and we jumped through a lot of hoops. It is the reason the 328 got a total redesign of the cooling system. Finally the factory threw their hands up, had us put on higher pressure caps, reduce the antifreeze content and redefined overheating as the point when the car boils over. If its not boiling over, its not overheating no matter what the gauge says.

100+ degree days and being in traffic was a real problem for them.

It is not a wives tale. Anyone in the dealers in a hot climate lived it in 84-85.

Did you find they were early production qv’s mostly, or was it all over the place, hit or miss, car by car? Besides the new cap and reducing antifreeze percentage, was anything else done that helped?

Thx

Years ago, actually two timing belt changes ago, I removed the AC compressor and never reinstalled it. This winter, I decided to remove the condenser to improve air flow through the radiator. When I remover the condenser, I found a good bit of "junk" between it and the radiator. Then I blew through the radiator fins with 100 psi shop air and released a cloud of dust and debris....enough to need to sweep up! I had to remount the Spall fans to the rear by the thickness of the condenser.
Will have to wait for summer to see if it helps my cooling issue.
