Noises

[Maffison]

My 2001 IS200 was making a ticking and whistling sound after its first long run. The ticking sounds like a car cooling down and the whistle was like an air leak. It's the only time I have heard it. I heard the noises whilst stopped with the engine running, revving the car made no change to the sound. The car is new to me and I know its well overdue a service, checked all belts except cam belt so far (which I will do this weekend). The car has 56000 miles on it. Any ideas on what it could be?

have you checked the radiator pal?

Ticking noise is the cats cooling down. Not sure about the whilsting noise.

The radiator is in good condition. I assumed the ticking was normal after searching old threads here. I had first thought the whistling was the exhaust, but when I started the car the next morning the sound had stopped. I will check fluid levels again tonight. The car will get another good run on Friday so will investigate a little deeper then.

Will do! If the rain holds off I will give it a run up and down the dual carriageway tonight and see if the noises return.

When i removed some time ago my rear seat, i noticed that the fuel pump was pretty noisy.

Maybe your noice is from there? Maybe your fuel pump is making more than normal noise?

Just an idea

Ok, back from a high speed run and the sound has returned. The ticking is definently the exhaust as suspected so no problems there. But the hissing sound seems to be loudest by the rear passenger side wheel. Is this likely to be a fuel pump problem? The hissing is not loud and there are no other sounds from it.

just sounds like the normal fuel pump working to me

Thanks Stav, thats reassuring. The car is new to me so i am still getting used to the sounds it makes
