Overheating with sand driving

Agree with all above.
Reduce tyre pressures if car is "working" on level beach
Pull radiator for external clean and flush if coolant is poor

How clean is the radiator

It looks clean but I will have a better look at all components

I've seen the radiator guys.....it's a solid built aluminium job :)

Haha ofcourse mate ;)


Thanks for all the replies guys. This give me somewhere to start.

I actually have two air gauges, a very cheap push on from repco and a more expensive gun from bunnings. We used them both so likely that the car wasnt in balance either. I reckon 20psi was too high, but I didnt want to risk running my tyres off. Next time I will go lower and just watch my turnings. Like I mentioned, its all new for me so I have a bit more the scares of things going wrong lol.

I will give it a service job as well (with NP99).

I'd be looking at air flow problems if all is well at high way speeds.
Not sure what the petrols use(viscous hub or thermo fan?)
I go straight to 15psi on sand,so much easier to drive and I find water temp is no more than easy highway cruising which is 86degrees C for me

If the water in the reservoir was boiling, tells me that there is some thing else is wrong. I`d get it checked out. It could be an air lock in your cooling system which may need to be bled out like the V6 Holden motors, thermostat not operating properly, split head gasket (if water is needed to be refilled, check your oil for milky white colour), check radiator fan and - thermo fan to see if it`s working and check the water pump, check radiator hoses / heater hoses and clamps, what`s in front of the radiator blocking the air flow, radiator might be clogged up or fins are bent up, radiator cap, etc etc. At constant speed / high way speed, the coolant will be cooled, but at low speed like beach driving, the cooling effect isn`t great. Start looking at the fan is working and then any thing cooling related. I have heard that gas makes the motor run a bit hotter than petrol and may cause the motor to run hotter a bit more in sand I`m assuming. If so, get the gas checked out too and see if the motor is timed in correctly.
