[DeTomaso] Overheating Issue

Hi Guys,

I'm the guy who was at wit's end. I didn't realize Will had posted  
this issue here on my behalf and I thank him and all of you who took  
the time to respond with great ideas and suggestions.

The person I owe the biggest THANK YOU to is my friend, fellow Pantera  
owner and expert problem-solver Bohdan G. He suggested my carb may  
have leaned out and wisely asked when I had last adjusted it. The  
answer did not impress him and he immediately came over and spent the  
evening helping (and teaching) me to adjust the carb. As an added  
measure of safety, I decided to move to a slightly cooler spark plug  
than I had been running. As we were finishing up and doing some  
running tests, one of my fan relays started acting up and we called it  
an evening.

Tonight another friend and car-guy (who is less intimidated by volts  
than I am) came over to trouble-shoot and locate a loose connection at  
the relay. Once all was tightened up, we went for a 45 minute drive  
(low and high-speed areas) and SUCCESS! The car ran like it did when I  
first got it. Strong and no pinging at all, even at the hottest temp.  
Never went over an indicated 195° on the gauge — WITHOUT using the  
second fan (my '71 has one switched fan, one thermostatically- 
controlled one). When we returned, I left both fans on and let the car  
sit idling for 30 minutes in my driveway and it stayed UNDER 195°.

I also took my new infrared temp sensor and found that the hottest  
part of my heads was 200°. My rad at the hot-in area read 193° when my  
gauge read just under 195° which suggests that the gauge is pretty  
close to accurate in my case.

Anyway, a HUGE thanks to everyone for their input, and ESPECIALLY  
Bohdan for SOLVING my conundrum.

Mark
