Questions
Will I handle refrigerant charging myself?
Yes, under the trainer's supervision with safety glasses and gloves, using the gauge manifold and vacuum pump.
Which vehicle parts are dismantled?
Engine, clutch, gearbox, differential, steering and brake assemblies available in the lab.
Is this course based on the BTEUP syllabus?
Yes. The units follow the BTEUP (Board of Technical Education, Uttar Pradesh) diploma syllabus. If your polytechnic follows a different board or a revised scheme, the centre teaches your own syllabus.
