Hey Guy I just picked up a 1926 Model T truck. Runs great and starts even better. But have 2 problems. 1st I think it is overheating. I say think because from what I have read it is ok to boil over sometimes. It gets Darn hot. I get steam at times running around town (say 2 miles or so on a 75 to 80 day, have not tried to drive it farther). It still runs great but I am not sure if this is ok. I can tell you it has no Thermostat installed. I have 50/50 mix of antifreeze/water in right now. I now read it can be a good thing or a bad thing depending on who you ask. Should I see a power drop/detnation before I should worry? What is truly better? Straight water or the 50/50 mix. How full should the radiator be when cold (how far from top)? 2nd I start the truck on the Bat. But when I switch to mag it dies. What should be the trouble-shooting steps I should take to find the problem? Is it bad to run on the Bat? I have read that the spark will not be as hot. I show charging on my Amp gauge in the car when running. So the generator is working (I would think anyway). I have lots of auto experience with cars from the 30’s on into today’s cars. I also work on Aircraft from the late 50’s (Lockheed Super Constellation Starliners, 4 engine piston airliners making 3,400 hp per engine) I also hold a Pilot’s license (starting the ford is a lot like starting those big R3350-988-TC18EA2’s on the conies) So I am not scared of machinery but this little Ford has got me worried. I don’t want to hurt it by doing something silly. Any help on this would be great. Thanks Guys. Great Site.
