Radiators and Air flow:



*Consider a larger radiator. Some Factory radiators are a 2 core and can be increased to a 3 core radiator.

*Please… resist fly screens where possible.

*Consider the size and positioning of driving lights, winch, number plates and particularly bull bar air flow.

*Check to make sure air conditioning condenser fins are clean!!

*If an Intercooler is mounted in front this can add considerably to hot air flow over the radiator and restricting air flow to the radiator.

*Consider installing a few small bonnet vents on the left and right of the rear region of the bonnet. This has proven to be a popular addition and has huge effects on under bonnet temps!! Considering how tight most engine bays are after a few accessories are added, this venting addition can reduce heat stress on a variety of products under the bonnet.

Engine set-up:

*Over fuelling can be a big cause of high combustion temperatures.

*Make sure the fuel injection system has been given the ‘once over’.

*If the vehicle is fitted with a turbo or super charger, over fuelling may be the cause. It is very easy to over fuel a diesel once plenty of air is available as possibly no smoke under load may be visible. Visible smoke under load can be a warning of over fuelling!
