Radiatoir is pissing a small amount of coolant. leaks one day but not the next. I just got this thing running and in looking it appears that it may have been leaking slightly for a while. There is a pretty green line down the inside edge of it. My question is is anyone knows if these things have enough metal in them to have it repaired or should I just bite the bullet and buy a new one?
If I buy a new one where should I look? Dealer or aftermarket?

 

Go new!! I replaced my radiator with a 3 row. The stock radiator is a single row radiator, I had some overheating problems with it in extreme conditions, like a full load, going over the pass (elevation from 0 to 4700) and 90 degrees in mid summer. I had to do a little trimming to the fan shroud, other than that it was an exact fit.
This is where I ordered it from ....

New, new, new.

Radiators are absolutely toss away, unless it is a relatively new one with something like a small rock hole that is easily repaired.

Don't put it off. Small leaks can turn into huge leaks in a microsecond; then you have bigger fish to fry!

 

SOME older radiators have plenty of meat in them to repair but most new stuff is too thin to bother with, if theres one spot thin enough to leak, theres 12 others ready to spring a leak as well.
