Over Heating 1973 Super Bettel

I have a 1973 Super Bette with the 1600cc I wet for a drive the other day. I live in south Texas average temp here is about 95 to 100 deg.. out side in the middle of the day. I drove about 20 miles when my Bug shut down on me in the middle of a construction zone.After cooling for about 15 min the Bug started up like nothing and ran just fine. On the way home I stopped once to let it cool. speed limit was 65 mph before the construction zone. I have been working on the Bug for some time and have not used it for some time now. I thought all was well with her before this. I checked for air flow from the fan and there is a lot of air coming out of the air ducts that are meant to go to the heater box, which I have just after this blocked off for more air flow around the engine. I still can smell like it is getting hot on the small trips I take to work and back witch is about 5 to 10 miles.

Q.. is it possible that the air from the fan is not getting to the cylinders to cool them off ? I have not got under the bug with it running to feel for air under the engine yet and do not know if this is the correct way to check.

Please let me know your ideas this car is for my teenage daughter to use this year to go to school in. Thank You, Ken

Get an oil temp gauge and actually measure how hot it is getting. Anything under (approx) 230F is acceptable.

OK but remember it shut down on me.

Ken...put the hoses back on to the heater boxes....do it NOW...seriously...the airflow is needed to keep them cool...very *little* cooling air is used when the boxes are "off", but without the small amount of air that goes through the vent on them to cool the boxes, they will do what they are designed to do...and that is transfer heat...if it can't transfer it to the air it will transfer it back into your heads....cracked heads is a real danger running like this...if you do *not* want to "waste" the cooling air order some "j-tubes" and install them in place of the heater boxes...(it is always a good idea to fill in the gaps in the hot air exhaust plenum below the engine when using J-tubes)

I had a problem like that when I first bought my beetle. It turned out the metal fuel line was resting on part of the manifold and the gas was vaporizing and causing a fuel lock situation. So it would lock and the engine would die from lack of fuel. Then cool off so the fuel would flow again and all was fine. Reworking the fuel line a bit fixed that.

yep, i reckon the fuel line is it as I had a similar problem.Someone else I knew said it was their distributor on their VW which needed replacement and that fixed the problem. I Also had a hotstart problem on my VW golf so it would drive 20 minutes, then when I turned it off it wouldn't start until it cooled down. That was the fuel transfer pump.

I have experienced this same problem on two 74 supers myself on outside temps over 80 degrees in the past. I don't know the exact cause but the fix is an in line electric fuel pump mounted under the fuel tank. It fixes it. Thats all. Dennis
