The water seems to shoot through the tubes pretty well on mine, but it doesnt cool worth crap. The upper hose tube is loose.
I want a radiator that flows well and is known to cool well.
I have one out of my 86 t type that always seemed to work good, the car was in an accident and I haven't driven it in a couple months but I remember it doing a good job keeping it at 160, my email is vanillaice782@yahoo.com if you're interested.
