Weird sound from front of GT3

[stg]

Out in the GT3 tonight and started hearing this sort of weird chucker-chucker (trying to find ways of describing it) sound from front of car.

Sit idle, engine running and its a noise just around the battery area (more drover side). Gets sporadicly louder the higher revs, but it fluctuates like a wave of increasing/decreasing wave of sound at constant revs, but is not sync with the revs themselves, just louder.

Cleared a couple of stray leaves from the air intakes.

Not sure whats behind the battery except cooling system? - will take the battery cover area off over the weekend, but ideas?

More likely the neighbours cat actually.

..

Wondered if it was aircon related

check the battery cover is secure, all the plastics under the hood etc.

Ajit.

Don't know the GT3 specifically, but normally the aircon compressor is in the "boot", belt driven from the engine. The brake servo and ABS unit is in the front - do the brakes feel normal with correct fluid level?

The heat exchanger lives behind the battery, the AC pump is at the rear of the car. Could it be an airlock?

It might be the wheel catching on the plastic brake
intake

Its definitely behind the battery area (more driver side), not really near the wheel and its happening when the car is stationary.

there is a fair amount of flimsy heater duct tubing high under the dash. Something could have come adrift?? Try turning of the blowers to check.

You can download the entire factory manual from here if you want to see what's where before you start.

There is definitely a pump of sorts for the aircon in that space - parhaps not the compressor, so my fault for giving it that name - that is of cours belt driven and in the rear!

When my aircon leaked there was a real squeaky noise from the whole system - but ony with the compressor running.

If you turn off the AC / CC does it still do it?

cheers
