My car is stock/original down to everything but the wear items. The engine compartment looks factory stock, although it is not a show car.

I have had to redo my radiator about every 2-3 years. (Please forgive my lack of tech expertise). I have had to have it re-cored or tank repaired on this schedule. My understanding is that last time this was done everything was new, they just reused the rad supports and the top which has the part number, etc.

That cost $475 and only lasted 2+ years.

I really don't want to put in some huge aluminum radiator in an otherwise original engine compartment. Also I am not really in a position to spend $1000 on something either.

Any ideas? Any ideas why it leaks so soon after repair? I have used 3 different shops who otherwise have a good reputation.

Thanks!
Mark
