A few years ago I bought a March pulley set from Summit for my small block. The set came with under drive pulleys. I had a problem with the alternator at idle. I call March and they said they could not help me. I call Summit and they exchanged the pulley. I ask her why would March would not exchange the pulley? She told me that I was Summit customer, not March's. Makes sense.

I helped Lainhart with his FE overheating problem at idle, worked as it should at speed. We found several large pieces of powder coating blocking the lower hose. He has a pipe that passes thru the front part of the fame. It had been power coated and the coating on the inside had turned loose and was tangled in the wire of the hose. We replaced the water pump with Edelbrock's high volume pump. Added a adjustable fan control to turn on the fan at 195. 25/75 anti-freeze. Now it will sit and idle for 40 minutes with no over heating.
It does not get below freezing here in North Alabama very often. And our Cobras are safe inside the garage, so we do not need as much anti-freeze as our Northern friends. Anti-freeze transfers heat 20% less efficient than water.

Three Cobra ago, 8 or 9 years ago, Coach had a overheating problem. We chased the problem for a month or so. Changed t-stat several times, different fans, etc. I was doing some reading on the problem and came across something about anti-freeze and heat transfer. I asked Coach how much anti-freeze he had in the Cobra. We did the cal's and it was about 80%. We drained it out and added back 25/75 mix and all was well in Cobra land.

Most of the over heating problems are a easy fix. Just hard to find.
