Nagual

I finally found what was the issue… I had a bad electric connection that was creating shortcuts in the alternator It results that it was the connection of the oil sensor that was incorrectly connected (wrong pin connected)

Thanks dutch I Will try that. My water pump seems pretty new (3y) The pulley was a bit too stiff when I take it out. May be it has worn out the bearings (?)

Hi I changed the fan clutch and no change :-( My water pump seems quite new…(see photo) I am hesitating to change it. What do you think ? I Check the damper pulley and it looks good

Some update I finally had the time to change the alternator and no change I am quite disapointed I must say Same f### noise I have no culé Except start a fire with the Z

Hi Yarb I Will test it with an electric drill to reproduce the sound if I can… Will see I Will update the post Hi Zed Thanks for the references and the info

I was checking to restore my alternator but it seems it s more expensive than a new one… I will go that road I guess… I checked on rock auto hard to understand the differences between the models and brand? Do you have an advice ? Terrepower, Rémy, pure energy have no clue about the quality ?

@Zed Head When i wrote that the spinning noise was heard after The motor stop, it s during like 1/2 sec (like a decreasing wizzz) and it s not everytime.

I have test w.o the alternator belt and bingo, no more noise ! When i move the pulley it s a Little bit rough and when moving up and down I have a small noise (see the end or the video) The water pump seems fluid and noiseless. Guess I have m’y suspect ? IMG_1803.mov

On the video I did not depress the clutch I did test depressing the clutch before starting the motor (but with no gear engaged) and same noise ,(

Hey In the video i took out the AC belt so it s not involved in the noise. Next try will be without Alternator belt to see if thé Sound disapear I ll take photos tomorrow Thanks

Hi all, looking for help on a noise issue that has me stumped after extensive diagnosis. I’m hoping someone has heard this before. Symptom: Regular metallic grinding/raking noise that appears as soon as engine RPM exceeds ~1200 RPM. Not a pop, bang, or knock — sounds like a mechanical part rubbing constantly, regular and continuous. The noise: Appeared overnight (started cold, ran fine at idle for 5 seconds, then noise kicked in as soon as I throttled up) • Same noise with original starter, used starter (Hitachi S114-254DAM), and brand new starter • Identical whether clutch is engaged or disengaged at 1300 RPM • Last time it occurred, I let the RPM drop back to idle and the noise continued for ~3 seconds while RPM was falling — sounds like a mechanical part still spinning by inertia • Recent context: aluminum radiator installed ~1 month before noise appeared (mounted lower than stock to fit thicker core)` I ve tested the AC bearing, and it s fine… Any clue ?
