1994 Camry V6 Overheating Issue

Hi,

The car's been driving fine for months, however in the last few days it's started reading overheating after about 30miles of driving to the point that the temperature gauge will sit at about 3/4.

It stays like this when the car is sitting idle after I have parked up. However I've noticed that it also appears to be making a kind of whining/droning noise as well, almost as though something is grating on something else. It seems to be coming from the side of the engine where the plastic cover is for the belt, at least that's where it sounds most prominent.

Not an expert mechanic by any stretch of the imagination, but the coolant is sitting just under full with Toyota's own coolant, I watched underneath the car for ten minutes or so after I drove home one night and there's no evidence of anything leaking to the ground, nor can I see any sign of leakage in the engine bay itself, everything looks pretty clean.

To be honest, I'm worried it might be a head gasket issue, or something else I don't know enough about. The main fan on the radiator seems to be spinning ok at what I presume to be the right sort of speed.

Apart from all this the car runs perfectly well with steering, power and everything else normal.

Does anyone have any ideas I can check before I take it be looked at? The noise in particular is worrying..

Thanks for any advice.

Andrew

Sounds are difficult to diagnose without actually hearing them but if the sound is coming from underneath the plastic cover for the timing belt, then it may be that the timing belt is stretched or the timing belt tensioner is not working. A technician at a Toyota dealership will know what it sounds like.

If the timing belt has not been changed for over 60,000 miles or it is over

6 years old, then I would definitely check the condition of the timing belt.

a loose timing belt can also cause the overheating condition.

I wonder if one of the impellers on the water pump let go?

It's possible, but I've never heard of that happening on a Toyota. I think the timing belt tensioner is not working and the timing belt is slipping on the water pump pulley

Could very well be that. I was trying to account for the "grating" sound he hears.

A timing belt that needs changing sometimes makes a grating sound.

Well it was in Toyota on Wednesday, they replaced the water pump, timing belt and thermostat.

The symptoms are still the same. I was back this morning voicing my concerns over the issue. They'd said they'd investigate before they did any work and then phone me if it needed any work to solve the problem other than the above mentioned.

They never did....when I spoke to them earlier they were somewhat apologetic, now they are thinking it's the drive belts, apparently the technician though they were at the stage of maybe considering replacement. Also thought it might be some play on the timing belt tensioner. At least there was some movement on the water pump bearings.

If anyone wants a listen check out the video below.
