Okay yesterday did change out waterpump, both idler pulley bearings why bearings? i discovered that those idlers what were sent to me are absolutely not for that car, much bigger and wrong hole diameters etc.... scratched my head looked for idlers nope none of those at sale again but then i discovered i can press bearings out of them, 4x bearings FAG made 4,50 eur piece, tensioner pulley
serpetine belt also firstly i thought alternator clutch is that thing what makes crazy rattling noise but once everything taken apart i discovered that culprit itself were tensioner pulley super vobbely and clearly could hear cracking noise if you spin with finger, idlers were actually fine but i still changed bearings on them. Alternator clutch i would have changed but sadly alternator shaft has no slot to hold it still in order to crack it loose, some alternators have torx or hex bit and with special tool you can hold it still i do have special kit for alternators but instead taking it off and onto table to change it out even tho its not bad yet i decided to skip that procedure this time.
When everything done and tryed to bleed like written on manual, first hours i spotted nothing wrong blowed super hot air front and back, did couple long test drives also no problems, but later that day engine light illuminated and egr cooling code on it, very well since i saw that post about it here when looking bleeding procedures before starting this job i knew that i may have lil airpocket issue somewhere, even tho car held temp fine and did not overheat or anything like that i deleted the code, jacked cars front end high and let it run over an our + also carried out vacume test if you ask why i didnt use vacum to fill system before it is because i had forgotten that i have that kit laying around
dementia kicking in at young age...anyway system held pressure very well no single drop after 3mins being hooked.
Now did couple test runs again havent seen engine light yet and hopefully i got problem solved who knows but seems like everything included with fluids on that particular Nissan needs extra attention
and that ascd function code been there since i got vehicle 3,5 years ago, every now and then it comes but i can not discover any function problems with speed holding system etc.
and video is up also incase somebody needs to see how i did it.
