Vehicle Overheating - Mahindra THAR CRDe 2015 Owner's Manual

EMERGENCIES
If the engine stalls while running, the power assist for the brakes and steering
will not work. Steering and braking will be much harder than usual.
If the engine speed does not increase
If the engine speed does not increase when the accelerator pedal is depressed,
there may be a problem in the Engine Management System, electrical or electronic
controls. In case of certain faults, the engine may go to limp home mode, which is
indicated by the check engine lamp. Have your vehicle checked by an Authorized
Mahindra Dealer as soon as possible.

12.3 Vehicle Overheating

If the needle in the temperature gauge in the instrument cluster is all the way up to
the H and/or the high engine coolant temperature warning lamp is ON, your engine
has overheated.
Upon engine getting overheated, the Engine Management System reduces engine
power substantially and may even shut the engine OFF; it is dangerous to continue
driving when the engine has overheated. You need to first cool the engine down
before starting to drive again.
Follow the below instructions to cool the engine down
• Progressively reduce the vehicle speed and bring the vehicle to a stop at the side
of the road
• Turn ON the hazard warning flashers
• Keep the engine running at idle
• Engage the parking brake
• Switch off the air conditioner
12-2
• You can keep the AC blower speed at maximum and set the temperature control
knob to the extreme end of the hot zone (clockwise end)
• Wait till the engine coolant temperature drops sufficiently such that the needle in
the temperature gauge is around halfway between C and H
Now switch the engine OFF and carefully open the bonnet/hood to visibly inspect the
engine cooling system parts. Be cautious while doing an inspection as vehicle parts
will still be too hot. Verify that the engine coolant level in the coolant recovery tank is
maintained between the 'Min' and 'Max' mark. Check for possible fluid leakages.
Check for damages to heat exchangers and connecting hoses. Also verify that the
radiator shrouds, engine fan blades and the engine belt all are in good condition.
If any evidence of failure is observed, contact the nearest Authorized Mahindra
Dealer for help. In case, no system leakage/ failure is suspected, driving can be
continued.
Either due to severe operating conditions or due to any system leakages or failures,
the engine can get overheated. However if the engine is getting overheated
repeatedly, even in normal operating conditions, get the vehicle checked by an
Authorized Mahindra Dealer as soon as possible.
Refer to the 'High Engine Coolant Temperature' section under the 'Features
and Control' chapter for details.
If the high engine coolant temperature warning is ignored, the engine shuts OFF
abruptly to safeguard engine components from overheating and consequent
failure. Abrupt engine shut-off can lead to uncontrollable driving condition and
accidents.
Stay clear of hot and rotating vehicle parts while visually inspecting the vehicle.
The coolant inside the cooling system is under high pressure and temperature.
