Don't forget too that often cooling problems can be a symptom of other
problems -- running rich, air in the cooling system, etc.

Subject: Re: [Mgb-v8] [Mgs] Repair or replace Radiator?
Bill,
It never is my take that any lister is taking a snipe at me. On the
whole everyone is polite and we all share experiences with no malice
a fore thought!. But I have to go by my experience and that is an al
rad replacing a virtually new brass one from D&D (no slouches in
quality) made one awesome difference. Now, admittedly, I have a
stonking V8 in the gnat sized engine bay and overheating is legendary
for V8 conversions but it did fix my problem. Whenever I go to V8
meets the usual cry for those with the dreaded hot flushes problem is
answered by advice to go to an al rad. Maybe the new copper is
Kurnifer which is copper and nickel???
