Can't say that actually. There are so many buses with ZF
gearboxes, but why must Habits catch fire? And. Theres also the MK2
and 2nd Batch Habits that have yet to catch fire.
Even if the bus is a Voith, a BC who doesnt checks water levels
will still catch fire. There are also cases of Voith-ed buses
catching fire in SG. Examples are Scania N113CRBs.
Here we have to go in to the fact that there are some batch 1 ZF
Habits which does not have intercoolers like some suggested. I have
not seen the engine personally so there is no proof whether which
has intercooler or not.
But even with intercooler it does not mean the engine would not
catch fire also, and once again, the CRBs are to proof also...
