CDNBullrid Posted November 11, 2008 Share Posted November 11, 2008 (edited) My pathfinder started making noise about a year ago. At first it went away when the engine warmed up, but now it is here to stay. It has the same sound as if a bearing was shot on an idler pulley, so i removed both belts and the sound was still there. I opened up the little cover over the waterpump? (in red) The noise seemed to be coming from a little higher. Is this the camshaft under this cover? (in green) I dont know what I should do next. I dont want to take it in yet. I am a Ag. Mechanic so I know how to use a wrench. Anyone had anything similar. I felt the chain when i had the one cover off as in the top picture, it felt tight. I dont know what path the chain runs though so it could have been on the tight side anyway.

nissandoms47 Posted November 13, 2008 Share Posted November 13, 2008 Water pump bearings? Mine makes a little bit of noise too but not as much as yours. Link to comment Share on other sites More sharing options...
Daddy Rim Posted November 13, 2008 Share Posted November 13, 2008 (edited) Water pump bearings? Mine makes a little bit of noise too but not as much as yours. I will echo this diagnosis as mine too is making a bit of a squeal but couldn't be bothered to repair it. Also the FSM points us in this direction with the NVH chart.

CDNBullrid Posted November 14, 2008 Author Share Posted November 14, 2008 thanks for the info. has anyone done the repair themselves and has a list of instructions for me. I know it is a fairly large job. Or has anyone had this done at a shop and can tell me the approx time it took for it to get done. any help would be much appreciated.

nissandoms47 Posted November 14, 2008 Share Posted November 14, 2008 It doesnt look too bad. Just remove the radiator and fan and drivebelts and take off the two covers, rotate the crank back 20 degrees to loosen the tchain around the water pump then replace the pump.

Daddy Rim Posted November 14, 2008 Share Posted November 14, 2008 (edited) You should probably download an FSM to help you out. But here is the water pump replacement from the FSM. May also want to change your thermostat for good measure while you have your cooling system drained.

02silverpathy Posted November 14, 2008 Share Posted November 14, 2008 (edited) Yes, what Doms said! Daddy rim is right too...but there are 2 thermostats if I am not mistaken...one out front and one in the back.

nissandoms47 Posted November 15, 2008 Share Posted November 15, 2008 Id say for the average person who knows what they're doing. 3 hours. Link to comment Share on other sites More sharing options...
CDNBullrid Posted November 25, 2008 Author Share Posted November 25, 2008 replaced the waterpump, noise is still there. Took to nissan dealer. they suggested it might be the timing chain. My pathy has little under 100k miles on it. They are thinking it might be stretched and running over the tensioner a little sloppy. Has anyone seen this before? Has anyone had this fixed? dealer guessed at about 2k for the bill to replace it. where could i find prices of just the chain? Link to comment Share on other sites More sharing options...
fleurys Posted January 19, 2009 Share Posted January 19, 2009 I started to get the same noise, but it goes out after warmup though.... here's some info for your chain, but i guess you already knew this by now.... di it turned out to be the timing chain ?? Timing chain, pathfinder - vq35de - VQ35DE 01-04 $82.08 $61.56 info was taken from everythingnissan.com Link to comment Share on other sites More sharing options...
