Radiator question

Whomp · 04-03-2003, 07:53 AM

How do you tell how many "passes" a radiator has?
I hear people say they have four pass radiators with a level of smugness rarely attained by man.

i feel like an idiot for asking this. It seems like it shoud be so obvious.

Thanks,

Whomp!

No Replies.

You ought to be able to tell, simply by observing very closely, your rad.

Got a pic?

Crap ... I don't have anyplace to host a pic.

more 'passes' = greater head loss
their "smugness" = foolishness

the number of passes refers to reversing direction

Well, being a bear of very little brain, all it took was a minute or two to figure out my heater core is a 4 pass. I think I may have too much heater core for my pump, but we'll find out.
I'm waiting on some 1/2" hose barbs from McMaster, then its time to put the whole thing together.

Hello!
I sent Your question to Hard Ware Labs and got this answer from someone called Willie:

The terminology was derived from the number of turns the coolant would make
inside the radiator.

A single pass rad would simply have two single-cavity top and bottom tanks.
While two pass radiators would have a single cavity bottom tank with a 2
cavity or dual upper tank (more reliable than single tank dual cavity)
configuration.

Hope it helps You.
