Trucks are tailored primarily for the haulage of cargo and are of supreme importance in the transport industry. Like any other man-made machinery, trucks are prone to breakdown. As a truck owner, you do not want to get stuck on the highway in the middle of nowhere at night due to a truck failure. During this time, calling a foreign truck repair would not be possible, and it is up to you to rely on your experience and manufacturer training to get the small issues fixed. The following are ways you can diagnose track issues to prevent grave pitfalls in the long run.
Engine Noises Indicators
The truck engine can make different types of noises. Each noise depicts a different issue with the truck and requires a different approach. For instance, as a do-it-yourself (DIY) truck driver, if you hear ticking noise from the engine, it implies that it is hot. This may indicate camshaft failure on the engine. You need to supply a quick estimate and complete the repair. If you experience the same noise and same failure numerous times, ensure that the issue is addressed by a foreign truck repair service provider.
Heating, Ventilation and Air Conditioning (HVAC) Diagnosis
HVAC diagnosing can be broken down into three basic categories:
Common air conditioning malfunctions result from refrigerant leaks. Most of these issues can be visibly detected by traces of refrigerant oil at the points of leak. Other minor leaks might require the use of electronic leak detectors or ultraviolet refrigerant dye. Common sites to check for these leaks are the O-rings and hoses at the condenser behind the grill.
Pressure analysis involves viewing of abnormal pressure patterns on both the high-pressure and low-pressure service valves. The abnormal pressures indicate a blockage elsewhere in the system or a weak air conditioning compressor.
Electronic testing can vary from compressor clutch, blower operation, temperature, mode and cooling fan. Most of these conditions can be diagnosed with testing of fuses, circuits, components and relays while others require a scan device to confirm incoming data and outgoing commands to confirm correct control.
The above are some of the most common truck problems that you can come across. To have an easy time troubleshooting these problems, you need to invest in a scan tool which you can acquire from a foreign truck repair service provider in your locality.

I love to take my car down to the track on the weekend. Running a race car is an expensive exercise so I need to be smart about how I spend my limited car budget. I do some of my auto servicing myself, but I don't have the equipment to some of the more complex jobs. I have put a lot of time and energy into my car so it's quite a commitment to trust someone else with my car, even for a few days, so I've found a trustworthy car service centre with a lot of experience in high performance vehicles. This blog has some tips on finding car servicing for racing cars.
