I've scanned the archives but didn't see anything. Is there a reason the bus manufacturers didn't put the radiators in the front? Other than long coolant lines and fan drive issues. |

I always thought an ideal place was on the rear,up on top...wonder what was in the scoop on those old buses that had scoops up there |

Bob, the ones with scoops are the Flxible Clippers. The radiator is on an angle with the radiator cap at the back of the coach between the engine door and the scoop. A set of kysor shutters was on some. Leaves etc. were a bit of an issue. The fan fit in a shroud on the engine pulling air down, forward and out the bottom. Great old coaches.
Godspeed,
Michael |

Our bus has the same setup less the scoop up top. Maybe Gm dident want to totaly steal the flex look on the rear. Some call it a camel back. Most of the early buses had front engines and radiators untill the mid 1930's when the rear engines started to take over. The Brills had mid engines and front radiators. I'm guessing it was pumping and reliability issues. |

Yeah, something about sending 20 to 30 hp all the way to the front of the bus to run the huge fans.
I may be exaggerating the HP requirements but its a lot to send through a 30 foot jackshaft and gearbox.
There was a rumor that the reason that Gas engines generally were not used much in rear pushers was due to cooling issues with the radiators in the back. GM built a few for the early transits but they were lucky to get over 50mph downhill with a 200 mph tailwind.
I had one once.. TGH-3102, 6-cyl GMC/Pontiac with an automatic ( cast iron )with a V-drive/angle box bolted to the end of the tranny. Truly a wierd deal. The radiator was on the passenger side right rear and the tranny was on the left side. |
