Noisy Innova Diesel upon cold start-up - is this normal?

[EL Chicane]

Lately, my Toyota Innova Diesel squeaks very loud during initial start-up. It happens during cold weather like rainy season. It was not squeaking like this loud before. Sounds like a metal-to-metal squeaking, but disappears after about 30 seconds.

I know diesels are noisy especially during cold start, but i never heard my Innova squeak this loud before. My odo is just 50k and i just changed oil last 2 weeks ago using Shell Fully Synthetic Diesel engine oil.

Is this loud squeaking normal? Again i'm asking because this is the first time it really squeaks very loud during cold start, then disappears after about 30 seconds or so.

Di kaya may loose sa belt sir? Pag mainit na kasi ang belt, mawala din yung inggay niya. Other thing is, sabi mo 50k na odo mo, maybe your using 5w-40 or even 0w-40? Ang alam ko kasi as you rack up mileage, mas maganda gamitin yung medyo may konting lapot na ang engine oil like 10w-40 or 15w-40 kasi mas better lubrication sa engine.

Best if you can record the noise.

Inspect/change the fan belt.

If it doesnt eliminate the sound, try inspecting the silicone oil level in the radiator fan. Maybe it is time to top it up.

if the coolant level drops a little bit, and you smell coolant there is something wrong with the cooling system 🤔

if not belt, check pulleys for the belt ... hopefully yan lang problem

100% yan pulley nga..yan ung pully maliit na parang tensioner bearing pag binaklas mo parang sprocket ng bisekleta ang function niya..may direction..

pwede mo rin patakan ng tubig ung belt pag nawala ung ingay sa belt lang un..

If it's a squeaking sound and emanates from the belts then it may be a belt or the pulley.

I just called Toyorama today to canvass for the pulley for a 2010 Innova D4d and was quoted P 1,500 for the auto tensioner pulley (not the whole tensioner assembly) and 2000 for the idler bearing.

my guess is, pulley. idler or tensioner.
i do not know, if the bearing can be replaced. if it can, then have it replaced. otherwise, the entire assembly....
you might try spray-on lubricant on the bearing. the squeak will disappear, but will be back after a couple of weeks.

the squeak appears in cold or rainy weather, because that is when the lubricant fails and/or the rust forms.

generally, no. it does not require immediate-to-hell-with-my-work attention, as in, it will fall off before you reach your destination tomorrow. but the sound is irritating...
mine has been acting up, on and off, these past months.

Search mo po sa youtube ang sound ng failing Overrunning Alternator Pulley or Alternator Clutch Pulley. Kung parehas sound then hook up a voltmeter during cold startup, if Vo drops during the squeal then sureball your OAP is about to quit.

Thanks for suggesting to look it up on YouTube.

This is what it exactly sounds like with my Innova problem:
How to Fix a Squeaky Belt (figure out where the squeak is coming from) - YouTube

Here is another exact sound just like mine:
How to Diagnose and Fix Belt Squeaks or Squealing Noise Issues - YouTube
How to Fix a Squeaky Belt (figure out where the squeak is coming from) - YouTube

So i guess based on the sound comparison with the YouTube videos, i guess my problem is indeed the belt.

I have never replaced the belt before. I believe the belt should be replaced after 50k?

Is this easy enough to be replaced by outside auto repair shops, or do i need to bring this to Toyota casa?

I'm quite wary with Toyota casa these days, as they don't allow you to watch while your car is being repaired. They just want you to stay in the lounge watching Mr. Bean videos. lol

inspect the belt, looking for breaks in the material. if there are, i'd replace it, even if it does not squeak.

I think kung regular ka sa casa nagpapa pms, pagka hit ng 40k odo mo replacement of belt's ata yan eh. Exemption nalang sa timing belt kasi 90k to 100k yun replacement dun. I might be wrong kasi wala sa akin ngayon ang manual ko.

+1 dito. alternator pulley.

nag replace ako nito at 60k kms. nung una tuwing umaga lang, cold start, hanggang sa kahit habang nag d drive meron na din.

ingat ka sa mga shops na mag sasabing kailangan palitan buong alternator.
