Overheating Question:

TexasKnucklehead said:
Hey, I hate to steal a thread, but...

I have a 74 TR6 with 'factory' A/C. The sun is too hot in Houston to drive with the top down during the middle of the day in summer.

I now have a useable top on the car and am considering fixing the A/C so I can drive it more in the summer. Normally the car runs cool, but any idling in traffic (Houston also measure distance with time), the temp needle rises. I've never over-heated, but I wonder how close I've been. Everyone I've asked with A/C claims there's no need to fix it, because the TR6s overheat when you try to use it.

The belt driven fan is a 12 blade 12" fan and the auxilary A/C fan (probably original dealer installed) is about a 6", 5 blade fan that appears wired to only run when the A/C compressor is running. (It looks like a bulky old refrigerator compressor fan.)
The normal shroud is not useable because of the condenser added in front of the coolant radiator -and was removed (probably during A/C install).

I'd appreciate any input/thoughts on resolving my anticipated over heating problem. Where can I find a temperature activated control for an aux fan?

Everybody here has some good ideas. I would follow them as best as I could. As far as the A/C goes, go for it. It gets hot here too, so I understand what you mean. IMHO I would trash the belt driven fan and go with 1 fan for the radiator side and 1 or 2 for the condensor side. Airflow is the key.

P.S. The compressor style you have is a York style compressor. Heavy. Used a lot on Fords. /bcforum/images/%%GRAEMLIN_URL%%/grin.gif
