Hi, I have already had this repaired once by Landrover. I am now again watching my thermostat move all the way to the RED when I am idling at a stop light, etc. When I turn the car off after a long drive, it sounds like it is going to blow up, very loud. Sounds like it is trying to cool down. If I am not sitting idle my needle stays in the middle where it should be which tells me that my cooling fan is not coming on when it should be. Any thoughts?

HI run engine until heat gauge reaches half or 90degrees .then feel top and bottom radiator hose for equal temperature ,IF not thermostat faulty. once you have replaced thermostat and coolant with required water dilution run engine by 90/100degrees engine cooling fan should switch on/off automatically .IF this happens system is fine.
Hi Heather, I'm Al the owner of Big A's Auto Repair
The easiest way to solve this problem is to replace the shifter unit itself. What happens is the solenoid on some units quits working and on other units the lever breaks and won't allow the shifter to move out of park. Give me a call from my website if you need further help. Have an awesome day Heather. Auto Repair
I have seen a few problems with the cooling fan on Land Rovers. Usually the relay portion of the fan fails. For a while Land Rover had fans on back-order because so many where failing. I would recommend having the fan/relay checked. FYI the relay module and the fan are usually one assembly.
It sounds like there is a leak of some sort. (hose, freeze plug, water pump, blown head gasket, etc.) The coolantlevel is probably low. You need to check it ASAP! Check the coolant level and if it is low you need to find out why and get it repaired...You DON'T want to overheat that engine! Especially if you have the 3.0L V-6. It only has to overheat once to do some serious engine damage.
At idling speed an engine does build up a lot of heat and the cooling fan will kick in. In slow moving traffic or traffic jams the temperature gauge can touch the red - particularly on hot days. The reason it cools down when you start moving is because of the air flow through the radiator.
Presumably there are no leaks from the cooling system otherwise you would have mentioned it. In normal circumstances the fan will not be running as you are driving at speed, as the air-flow through the radiator is sufficient to cool things. The fan only kicks in to get rid of excess heat - and this usually occurs at idling speed or after you have parked the car.
If the fan is running all the time as you drive, this points to either a fault in the fan switch, or the car is running too hot. presumably in normal driving the fan isn't running and the temperature gauge reads normal?
It is common - in stationary traffic many cars overheat (particularly big engined models) try to stall and 'cut out'. Restarting can be difficult until the engine cools down.
Is your car overheating in normal driving conditions or just at idle speed? Overheating in normal driving conditions can be caused by things like a failing water pump, blocked radiator, collapsed hose, faulty thermostat or, in the worst case scenario, cylinder head problems.
Overheating at idling speed is 'common'. Check your coolant level. If your car isn't using/losing coolant then there probably is no major problem. You can flush out the cooling system and refill with new coolant - and also check your radiator. Are the cooling fins crumbling with age? Or maybe they're partly clogged with insects and debris from the road? A blast with a hosepipe wil sort that out ..
The question is how much does your car overheat in normal driving? If it doesn't .. it appears as though you have nothing to worry about as such. Most cars have 2 speed fans... the 2nd faster stage kicks in at some point dependant on engine temperature. Perfectly normal.
Because you have done so many repairs already I would most likely say that the gauge is defective. I would use a manual temp probe and probe the coolant temp after the car has reached operating temp. Coolant will be between 180- 230 degrees. If coolant temp checks out and you can see coolant moving in radiator and the vehicle does not overheat then you will need either a gauge or a coolant sensor. To locate the sensor it should either be mounted in the thermostat goose neck housing or the intake manifold.
It sounds like a cooling fan problem. You state the temp runs high when at a stop and idling, but goes down once you start moving. If the fan(s) are not operating, moving forces air through radiator keeping the temp at a normal range. Have the relay/fuse for the cooling fan(s) checked. They are located under the hood in the main fuse/relay box. If they are good, check the sensor that sends the signal to the fan(s). If it is good, then it could be a bad motor on the fan(s).
