There is a port on the front side of the passenger side head and a port on the back of the water pump where the heater lines come out from. Maybe you could plum it in there somehow. We have Webasto heaters that are plumbed inline with one of the heater lines, the only problem though is that if the heater valves are shut off, they dead head and don't cirulate. |

Our buses with T444Es put out heat maybe better than any other diesel we have, especially with AT545 Allison transmission (no overdrive or lockup convertor). You've checked the thermostat, water valves open & etc.? |

Shut the heater valves completely off and start the COLD engine. Feel all the hoses and the radiator to find where the heat is going and coming from. If the transmission has a retarder, an additional hose will be circulating coolant thru the heat exchanger possibly located in the lower radiator tank without going thru the thermostat and will slow the engine warm-up.
I WOULD NOT INSTALL a tank heater.
The 444E has a frost plug location for a heater. All 444E early engines were equipped with a frost plug heater. If yours already has it all you need is the new cord that plugs into it. |

The engine takes forever to warm up or the bus body/heaters do? Each would be a different circumstance. |

Yes mine puts out great heat and does as it should ONCE it comes up to temp it just has to sit and run on fast idle for such a long time last winter when it got bad cold over an hour.one of these would have it warm |

So you want a bus that has instant body heat? You'll need an aux fuel fired heater to accomplish that. Espar and Wabasto come to mind. |

Or a propane. lol It's just interesting to me how many of these problems are solved with a propane engine. That is all, carry on. |

It will be very interesting to see how much the gas Bluebird Vision costs to purchase in comparison with diesel and propane powered buses. |

Most older diesels don't warm up well at idol. Let it warm up not longer than 15 minutes get in and drive to the first stop and the bus is warm. They warm up faster when being driven. |

In 1964 I started to do my own cold weather Minnesota testing and I shared my test results with Blue Bird engineering for many years. The head engineer personally verified my SUPERIOR HEATING & DEFROSTING results with extensive testing recorded on new Bluebird school buses during testing in Canadian January Winter temperatures.
WARMING A COLD BUS IN WINTER (without a auxiliary furnace)
1. Close the water valve for the bus interior. 2. Start engine & set on quick idle. 3. When engine begins to warm, open heater water valve "SLIGHTLY" to help defrost windshield and start driving. 4. When engine gains good temperature continue opening heater water valve only as far a necessary. 5. Always set for fresh air as engine gains temperature. This system would efficiently be done automatically if the school bus manufactures would spend a few dollars to standardize it. (The heater water valve would open if a auxiliary furnace was turned on) |

Instead, the typical bus driver will start their bus, turn every heater on high speed, go back in the bus garage and expect a miracle when they return 15 minutes or so later. I have even seen drivers kick them off of fast idle because they don't like to hear the engine "roar". Or they will come in off the route with every heater on high with 1/3 of the windows partially open and complain about the bus not heating well. |
