Subject: Re: [Healeys] Overheating so hard that the carbs boil?
Here's a few thoughts....
I'd be cursing out of town too...
1. Check the thermostat. Is it not operating?
2. Check the radiator. New? Yes, but is it already blocked from crap
in the block/ head?
3. What is the capacity of the new aluminium radiator?
Everyone knows the best way to reduce weight in a radiator is to make
a smaller one. ie less water. That's the REAL advantage of an
aluminium radiator. Make it hold less water. The weight is the water -
not the vessel holding it!!! Make it smaller capacity - Then it weighs
less. It's not about the minimal weight of an alloy version.
Aluminium radiator = smaller capacity = less water = less weight.
Fine on a race car, not so good on a road car.
4. I think fuel boiling is a symptom. But as already suggested, wrap/
ceramic coat exhaust. Are heat sheilds already in place???
5. Air deflectors -std - already fitted?
6. NEVER put a fan on the outside of a radiator in a Healey. Not if
you want it to run at optimal temperature (180 - 185). It blocks too
much air flow.
7. If all else fails - redistrip/ chemistrip the block.
