Tech Tips


Charging System and Electrical Diagnostics

Charging Problems can be caused by electrical faults in the charging system itself, by poor wiring connections at the battery or elsewhere, or by a slipping or broken drive belt. Most batteries will run out of power after 20 to 40 minutes of driving, depending on the load and battery-reserve capacity, if there is no Read More...


Choosing a Wiring Harness

When selecting a wiring, harness, look for one that has the following features for a fast and simple installation: 1. Good Length: Long enough to allow for you to neatly secure the wiring from the lights to the switches in the cab. Too often, the cable is not long enough for the size of your vehicle or the location of the lights you want to install Read More...


Diesel Injector Installation

When Fitting diesel injectors it is critical to ensure the injector sealing arear at the cylinder head is free of contamination. Contaminated injector seats can lead to: 1. Engine compression leaks. 2. More importantly, carbon residue on the sealing seat of the cylinder head can act as a thermal insulator leading to over heating and Read More...


Holden Astra Misfire Fault

Tech Tip explaining some of the causes and fault finding procedures in diagnosing combustion misfires. Causes: Engine misfires and associated fault codes stored in the ECU memory can be a result of many electrical and or mechanical malfunctions. For instance, a lean Air Fuel mixture due to excessive air leakage of a faulty EGR valve Read More...


Holden Timing Chain HFV6 Engine

Excessive timing chain wear ultimately resulting in timing chain link elongation can cause the malfunction Indicator Lamp (check engine light) to illuminate and generally the ECU will log the following fault codes. P0008, P0009, P0016, P0017, P0018 and P0019. Evaluating these codes (see below) a strong relationship exists to “Crank and Cam Sensor Position Correlation” Read More...


Importance of Oxygen Sensors

Oxygen sensors are vitally important and highly misunderstood. They are Pivotal for providing feedback to the Engine Control Unit (ECU) to trim fuel supply to the engine and thus ensuring the highest fuel efficiency and lowest emission. Oxygen sensors read the oxygen content of the exhaust gases and compare it to the oxygen level in Read More...
