Australian 4WD Action – August 2019

K

eeping on top of your

cooling system is

one of the most

critical aspects

towards prolonging

your engines service life. Not

much else will stop a 4WD with

potential catastrophic and

expensive damage like a failed

cooling system. Think of it this

way, if your cooling system fails,

the next thing to go is your

engine which means big dollars

in repairs. Even though summer

is still a couple of months away,

the best time to get your cooling

system in good working order is

before it gets too hot!

But it’s not just a dodgy

radiator cap, split hose or low

coolant level that causes your

engine to overheat. Other things

like a missing fan shroud,

sticking brakes, or even a bad

engine tune can all increase

your engine’s operating

temperature. That’s why this

issue we’re going to take a

closer look at the lesser-known

reasons why 4WDs overheat -

the sorta’ stuff you might’ve

over-looked on your service,

but could be waiting to bite next

time you head off-road.

If you’re about to perform

some maintenance on your

engines cooling system, then

make sure you checkout this

issue’s DIY too, because we’ll

show you how to upgrade your

radiator and get your cooling

system in tip top shape!
