Air Brake System Repair at Your Mobile Truck Repair Service
We have a few guidelines to better manage your air brakes. Within the air brake system, we service compressors, governors, dryers, valves, fittings, lines, hoses, chambers and abs systems in the air brakes systems. These are a few tips for monitoring your air brakes.
- Monitor your minimum operating pressure. Be sure the minimum operating pressure for a vehicle airbrake system is no less than 85 PSI for a bus and 100 PSI for a truck. All mobile truck repair service companies should do this.
- Watch the time/build-up rate. Be sure that t takes no longer than two minutes for air pressure to rise from 85 PSI to 100 PSI at 600 to 900 rpm.
- Monitor your cut-out governor pressure. Be sure that the correct cut-out governor pressure for the air compressor is between 120 PSI and 135 PSI. Cut-in pressure is 20 PSI to 25 PSI below cut-out pressure.
Coolant System Repairs by Mobile Truck Mechanics
Our mobile truck repair specialists are highly trained on all coolants systems. We typically find that a a semi radiator leak commonly occurs in one of the corners of the radiator or at one of the connections or a seam leak. The key to most radiator leaks is that they will normally start slowly and show signs of seeping well before a complete failure. We find that you should be able to spot coolant leaks before they affect your vehicle. We are happy to help with mobile semi repair.

Heating System Repair by a Mobile Truck Mechanic
Most mobile truck mechanics should be aware of problems with your truck’s cooling system that will affect your truck’s heating system. For example, low coolant levels typically affect the heating system’s ability to warm your cab interior warm. We typically find that leaking coolant can be attributed to a damaged heater core, radiator, heater hose, or cooling system. If you notice sweet smells coming from the air vents that is a sign of a coolant leak. Other common issues include a vacuum leak, heater valve failure, fan motor failure, heater core failure, or stuck thermostat. One of the most common causes of breakdowns is overheating, but heating system maintenance can help prevent this from happening. Consult your owner’s manual for recommended inspection intervals for the various heating system components, and be sure to seek out heating system repairs when necessary.

The most obvious cause of a diesel engine having problems by overheating are listed below. Our mobile diesel mechanics always check the following

- Malfunctioning diesel fuel injectors can cause your engine to work harder to compensate, causing overheating. Perhaps, there are build-up of deposits on the injector nozzle or a part malfunction.
- Also, a malfunctioning cooling fan can cause the engine to overheat. Things to check include a loose or misaligned fan. Other causes of a malfunctioning cooling fan are a defective coolant sensor, engine thermostat, or fan motor.
