Overheating 390

[pgold]

It is not as good as a multi pass or horizontal tube rad, but they fail to tell people that, but it is a nice rad for what it is, but it would be next to impossible to run a stock fan and fan clutch on it.

  Core, top and bottom tanks are all 3" thick so need to allow for that. But is designed to mount in stock 69  24" mounts. Has 58 tubes   1/8" x 1 1/4" x 16" in two rows. If you want copper they make them to but in 3 or 4 cores.
  Bottom line factory 24" 3 core wasn't doing the job and this radiator does with A/C running.

The thinking now is less rows (2) but longer tubes getter better heat transfer! IMO!!!

Hey Paul,
Reading this it seems like you're having a go at me, but that is exactly what the link says!

Cheers Phil.

That's because that aluminum rad has more volume/tube area than your stock rad, so you are not comparing apples to apples, if you had a 5 row stock rad, or a 4 row high efficiency rad, you would notice absolutely zero difference between those and the aluminum one.
