Greetings from Mongolia.
My 2007 Toyota Ractis (NCP100 1.5L 1NZ-FE) with 190'000 km makes these noise when the weather was -30c overnight. Bought cheap russian brand coolant, and it froze (Even the remaining 2litres of fluid in the container that i stashed in the trunk got froze too). Then I didn't know all the hoses and radioator got full of ice.. and drove the car and broke the serpentine belt, and changed that with bit shorter one (searched and found out it should've been 4PK1180). Now the alternator placed bit closer to the engine. Then I flushed all the coolant, fully changed coolant with anti-freeze, changed engine oil, and transmission oil... even changed spark plugs and coil rubber.
Somehow few days later. When it's too cold outside, when i started the car my car makes such noise, starts like this in the video, then the noise become continuous, then about 2-5 minutes later noise goes away..
I recently brought my car to a local toyota dealership, and the mechanic said the AC is getting worse.
Do shorter serpentine belt cause the noise, or is there electric issue at the ignition part, or it's just the AC motor that went bad from freezing the radiator and such
If coolant froze inside in the engine there could have been internal damage. From what I could find online that engine appears to have an external, belt-driven water pump. What you could do is BRIEFLY run the engine with the serpentine belt taken off and see if the noise persists. If not, then spin each pulley feeling for wear and roughness.
On the other hand, if the noise does persist with the belt taken off then you have internal engine damage from the coolant freezing.
Well there certainly is something making a lot of noise pray that it's something like the water pump when it frozen parts got broken it's rubbing and not internal engine problems like cam damage or bearing damage
