HI I’m using a 2003 Nissan Pathfinder as a weekender. We got it about month and half ago.. Car has been doing
well all this time on slight off road and weekend running. Now the summer heat has started rising and the outside temp is around 42C. During last weekend dune bashing ma engine got over heated and temp was rite at the top of the gage, Then toped it up with water ( no coolant was available) then towed it out of the sand to the tarmac. Gave about 30 mist for the engine to cool and drove back about 20KM to the gas pump the temp gage was at ½ way or one bar higher at the Gas pump Fill up about 3 ltrs of Coolant once engine cooled down, However now when I’m on the high way the temp gage is about ¼ up and if slow drive/ in traffic is goes up to ½ or one bar upper than half. Note that the gage was on ¼ all the time before this.
Add to that the coolant levels have not dropped in the radiator last two days. The resave tank is almost empty though. also the car is been only used not more than three days a week. I have an appointment with ma regular garage today eve.
Should I modify the cooling system if I’m to do off road with the pathy? Or is it normal? What mods should I do if I am planning on serious off road with the pathy, I’ve seen below mods been done on pathfinders cooling systems..
• Additional fan
• Transmission cooling system
• Heavy-duty radiator.
Appreciate your suggestions and advice on this…
Cheers

I would sure as hell get the cooling system checked that's for sure, loosing that much water is not suitable in any vehicle.
I don't no anything about the Nissan but a pressure
check will not go astray, then run your hand over all the hoses and conections there has to be a leak there somewhere maybe even the radiator tank has a split.
You can do this Hot of course with the engine off put plenty of coolant in you can then either see the leak or start to smell it as coolant has a sweet smell when steaming out the cooling system.
Cheers

hi path
my guess would be that the radiator fins is blocked up with maybe insects/grass/dust /mud have you looked between the radiator and the air conditioner cores it may be blocked up
fairly common problem and if you dont know the vehicles previous history of a 2003 vintage
the thermostat may be sticking or the water pump could be failing its not uncommon for a water pump to spit water out
have you checked the drive belt it might be worn as
well and slipping when the engine gets hotter than normal driving in heavier conditions
dune bashing is heavy work on any engine and the temp will usually go
well above normal on a hot day
there could also be a soft radiator hose that is collapsing
if you cant do the above yourself
it needs to be taken to a specialist in above fields
at ten years old it could be all or some of the above
but if you don't get it fixed you could quiet easily
cook your motor
cheers

QUEBBAMBIDDYBUMTAL and guys Thanx a ton for the input. The pathy was with a family friend of ours for the last 8 years and
well looked after it still goes to the Agents for every 20k Service.
The new developments are. I did regular running of around 100 kms today. The water levels have not dropped no overheating outside is around 40C . mechanic checked the radiator and pressured it up, no leak was visible. he advice to change the cap and run for few days to see if the water level is dropping. If dropping he said we'll investigate further.
Cheers will keep you posted.
