LCR ticking/ whirring noises on idle

[DOLBY]

hi
ive had a funny ticking type noise coming from the car for a while now, always on idle....now when this happened before i was told it may be the belt tensioner which i had changed...and if im honest the sound never went. The car was looked over but nothing found, but seems to be getting louder now. The car is 4 years old now and im a bit worried it may be the timing belt?

also, after normal driving and after switching the engine off i can hear a horrible whirring sound which im sure is the car cooling/recirculating the oil (even tho i always warm down the engine)...but this sound is really getting sqeakier and louder too....

any help guys?

Hiya fella, think the whiring noise after shut down is pump for coolant for turbo, mine makes a humming noise which lasts for 2-3 mins, maybe yours is on its way out if its getting loud, its located near front of engine bay sort of near radiator, like a silver canister.

The clicking is normal ( middle left side engine bay) by coolant bottle carnt remember wat it is now tho sry

Carbon canister maybe

thanks jim, yeh must be on the way out, it used to hum as yours did but is getting continuously louder......does this need changing asap or will it be fine for the time being?

hallyCUPRAR are you sure this is normal? im sure i never heard this when i bought the car.....cant be normal, doesnt make te car sound right...

Hally ment the carbon cansiter, its normal they dont do it all the time and are next to the power steering reservioir and coolant tank.

radiator fan? theoretically as soon as you kill the ignition , engine oil isnt being circulated, its purely mechanically pumped, as is the coolant via the cambelt/waterpump,

pop the bonnet and have a listen to where its from, radiator fans can run for a fair old time after,

bret if its got louder id get it looked at, the electrical water pump isnt very big so i doubt it would be too expensive, i supose a bearing could go on the pump which could make it sound louder, is there any one near you with another LCR to swap over pump to see if that cures it before you buy one, i know mine sometime changes the frequency of the humming sometimes but as long as it keeps buzing im happy.

EDIT to my post, i didnt know the LCR had a second aux coolant pump*
