Hi all,

Please for the car enthusiast and mechanics in the house, i need your input.

I own an Infiniti QX56 vehicle and for a while now i noticed that if i use it for say a straight 1hr or more drive, the temperature just starts rising, also further minutes down the line, all the indicators on the the dashboard will go flat except for the fuel gauge. This flatness last for a few mins before they start working again but sometimes when they come up, i will then realise that the temperature has gone so far up.

Now i have taken it to my mechanic and the electrician, they have checked everything, the fan is perfect, they even changed the cover of the radiator and touched the fuses etc but they cant find out the reason for such overheating most especially.

Infact because of this i have restricted the use of the vehicle for only short distance journey like church etc, even at that, i pray there will be no traffic, cos thats when the temperature will like to feel like it will embarrass me.

Please what can possibly be wrong?

Cheers all.

Could be anything. Is the SES light on? Have you checked the thermostat? There could also be a short on the grounds somewhere. What's the mileage on the vehicle? Fuses may still need to be checked beyond "touching."

One way to find lasting solution is to Scan the vehicle first to identify possible cause & paste resultant codes here thereafter

Will get the mileage when i get home but no SES light is on though sometimes, some lights can just come on ,on its own.

Will ask the mechanic to get some codes for me next time am at his workshop.

A scan would not reveal an over heating issue. Carry out a coolant pressure test. You could have a blown head gasket to a leak some where in your cooling system. If you need a permanent fix call 08156087872 or 08165520837 if in lagos

This may be far-fetched, but I've read of instances (in Nissan Maxima) in which overheating is caused by worn-out spark plugs.You may explore that angle too especially if your vehicle has a high mileage.

Yes spark plugs can cause over heating if not well to torque to the manufacturer's torque rating

Thanks Mayor and Costee...will try out your suggestion..

But where is your workshop Mayor?
