Ticking noise from water pump

[Tane Moore]

My 2zzge engine has just started making a distinct ticking noise that increases with revs coming from timing chain side of the engine. 

Took it into Toyota and he said it the noise might be coming from the water pump(no record of being replaced, traveled 215k).

Just wondering if anyone else has a problem similar.

He quoted $1200 to check the timing chain stuff, unsure on the cost of water pump replacement though. 

Cheers Tane

Hi tane

do you here the sound when idling at all. You can try removing the serpentine belt and running the engine. If the sound is here that indicates it's not the accessories causing it

Yes I do hear it at idling, how easy is that to do myself?

Release the tension on the serpentine belt from the belt tensioner. There are 2 nuts on it you are after the fake but which is cast into the part. Use 19mm socket on that and pull to the front of the car. A long extension bar helps a lot. This action compresses the belt tensioner so at the same time you can skip the belt off one of the pulleys. Then slowly let go for the belt tensioner to return position. Then all it takes it taking off the belt remove it from the engine. 

 

When end you start the engine do not do it for a long time without the belt on. Under a minute. If you think the sound occurs only when your car is warmed up, warm it up before you take off the belt but it may be harder when the engine is hot be care not burn your hands.

with the belt off and running the car if there is sound still then it's the timing chain

This diagram should help.youll need to install the belt back on. Not that hard but takes patience as the space is limited for your hands even using a coat hanger can be tricky. Once the belt is back on you should release the air from the tensioner. To do you pull that 19mm all the way forward then very slowly let it go back repeat that for 5 times

fupo1, thanks heaps for the info!

Might give this a crack and save some coin!

Update:

Just took the belt off and the noise is still there....

Surprising easy to take off,  and only a few minutes longer to put back on. But that involve getting under the car and also using the coat hanger.
