Why do bus drivers have the heating on in the summer it 25de

Why do bus drivers have the heating on in the summer it 25degrees out side and nearer 30 on the bus, , madness

As Ex bus driver Heating is turned off, by stop taps in Engine compartment. Its a job for the grease monkeys & they forget. and because we have such lousy summers world warming?? Bolocks its easier to leave it on otherwise you d have freezing busses in the Winter.

Been there

i KNOW., then they do not have it on in the center of winter. clueless.

For all the old dears wrapped up like they are going to the Artic.

Depending on where you are sat you will be over the engine too, which may warm things up a touch.

Next to a drug dealer, pimp, or traffic warden, being a bus driver must be the most empty sad existence on earth. they try to sweat the whole thing out in some way ?

I know its mad .

everyone on a bus is freezing in the winter and roasting in the summer when will a bus get the temperature right ?

I work for a bus company and one reason is that leaving the heating on in the summer helps cool the engine down. Buses overheat quite easily caused by the engine being at the back and no air flow to cool the engine. The only thing that cools it's the engine fan which isn't enough in hot weather.

OMG I KNOW. they are MAD..

The most of the heating on buses is attached to the engine cooling system. If the 'heating' is turned off then it's greatly probably that the engine will explode when it gets too hot.

they have to endure it also and you may be able to get off the driver has to ride it out //not being a bus driver I have no idea why this happens//anyway 25 degrees where are you ?not in UK that is for sure

Drivers do not generally have to endure the same heat. They usually have a separate ventillation and on occasion air conditioning system in their cab, which with all the security screens these days makes for a pretty selcuded environment.
Passenger saloon heating on more modern/advanced buses can have solenoid valves also as the original engine bay gate valves, so the driver can turn the heating off.
Bus engines don't overheat if the saloon heating isn't used there's something else wrong with the car.
