Hi Pajero GDI V6 3500 once temperature reaches normal level and I swith off the car it's not starting. I have to wait or put cold water in the radiator for it to start again . Please help

Check the coolant level! You may be so low that it isn't able to circulate between the engine block and radiator. Add water / coolant mixture to the radiator when the engine is *cold* and then start the engine. Continue topping off the radiator as the engine reaches normal operating temperature. Finally, add water / coolant to the warm / hot level indicator on the coolant reservoir.

How are you sure it is overheating? Temp gauge? Most likely are stuck thermostat, bad fan thermostat switch, bad fan. bad head gasket. Coolant going into overflow when hot is how that system is suppose to work. As it cools, fluid is drawn back into radiator. It it is not really overheating, bad radiator cap can allow coolant into reservoir more than normal.

new fuel filter possibly or may need new fuel pump

You must Run the scanner for to see which is the fault exactly. Maybe you have problem with the thermostat, clogged heater , low level water, radiator clogged. fan/water pum drive is slipping intelet or outlet water hose clogged, water pump defective., temperature gauge faulty, engine loose cylinder head gaster, engine block is cracked. leak hoose, radiator,etc.
God bless your.

with cold engine refill radiator, leave cap off, crank engine if water spurts up out radiator is a head gasket or head fault, these heads are not resurfaceable new head would be required

DID YOU BLEED AIR OUT THE COOLANT SYSTEM.TO BLEED COOLANT SYSTEM, FILL THE COOLANT SYSTEM THROUGH THE RESERVOIR TANK OR THE RADIATOR UNTIL THE FULL COLD MARK IS REACHED.BESURE TO USE 50/50 HALF WATER AND ANTIFREEZE.YOU CAN BUY ANTIFREEZE THAT IS ALREADY PREMIX 50/50.AFTER ADDING ANTIFREEZE TO RESERVOIR OR RADIATOR FILL RADIATOR TO FULL MARK OR IF YOU DONT HAVE RADIATOR CAP ON RADIATOR POUR ANTIFREEZE IN THE OVERFLOW JUG UNTIL COOLANT LEVEL STAY THE FULL COLD MARK.WAIT AWHILE UNTIL COOLANT LEVEL STOP DROPPING.NOW INSTALL THE RADIATOR OR OVER FLOW JUG CAP.START THE ENGINE AND ALLOW IT TO RUN UNTIL NORMAL OPERATING TEMPERATURE IS REACHED AND THE UPPER RADIATOR HOSE BECOME HOT.STOP THE ENGINE AND OBSERVE THE COOLANT LEVEL IN THE OVERFLOW JUG. THE COOLANT LEVEL SHOULD BE AT THE FULL HOT LINE.ALLOW THE ENGINE TO COOL UNTIL THE AMBIENT TEMPERATURE IS REACHED THEN CHECK THE COOLANT LEVEL IT SHOULD BE AT OR ABOVE THE FULL COLD LINE.ADD MORE COOLANT IF NECESSARY. WARNING BECAREFUL WHEN OPEN THE RADIATOR CAP OR JUG OVER FLOW CAP.USE A LARGE RAG OVER THE RADIATOR CAP TO KEEP FROM GETTING SCALDED.OPEN RADIATOR CAP A LITTLE AT A TIME TO KEEP FROM GETTING SCALDED.WAIT UNTIL ENGINE COOL DOWN BEFORE OPENING RADIATOR CAP OR OVERFLOW JUG CAP.WEAR SAFETY GLASSES.

It should be on the cyllinder block just below the head

I have mitsubishi Pajero GDI V6 3500, i was on the high way and suddenly the movement became very slugsih. i contacted my Auto mechanic who discovered that one side of the engine is not performing, the left side exhaust was cold while the right side was hot. ie the cold side injection nuzzles does not work , please what could be the possible solution ?

sounds like the cabbruter is losing pressure cheak tubes may be lose or damaged

• try disconnecting the cruise control module as a test...
