So, you have looked at a range of OBD diagnostic tools that are available on the market and you have come to the conclusion that they actually are extremely useful items to use.

You have then taken it one step further and went ahead and purchased one, but now there is only one issue to focus on: how exactly do you use it?

The sole purpose of the fuse box in your car or van is to protect every electrical circuit in the vehicle. There are a number of circuits in your vehicle including the main computer, the engine, the transmission as well as components such as the lights and windscreen wipers. On occasion, a relay or fuse can blow, which in itself is a quick fix, but if replacing the relay or the fuse does not rectify the issue then the problem may be the fuse box itself.

The radiator of any car is an essential component related to the cooling system, ensuring an engine does not overheat and create a component's failure. It is an integral part of the cooling system that discharges heat from the coolant within the cooling system into the atmosphere, resulting in a cooling process known as the thermal transfer.

When first investigating signs of a leaking head gasket, the cap of a coolant reservoir or radiator, should not be opened on a hot engine! The next step is checking the oil dipstick and if it’s showing a higher level than normal, the cause could be coolant leaking into the crankcase, by way of the cylinder. This can be confirmed if the oil dipstick displays a milky, yellow, or brown looking substance.
