so its 0-10 degrees here now, and when i start my car up and put it in gear after warm up theres a rattling noise coming from the engine. i couldn't point out where its exactly coming from but sounds like somewhere from the front of the engine.

i dont know if it can be the UR pulley doing something...but as soon as i drive it even for a few seconds it stops or even if i put it back into park and back into gear it completely stops.

but i did notice that my engine coolant reservoir is almost empty. what do i use to refill it can i just get a mobile1 collant or do i need to go to the dealer?

also i have 20k miles on it i ALWAYS warm my car up in winter or summer is it normal for the coolant to be low after a year?

should i be concerned?? thanks

 

I think the coolant increases once you turn off the car, I might be wrong someone correct me. So you might think it's low cause you're car is on, turn it off and check again.

 

i would recommend just getting NISSAN authetic coolant as some cars (TL for sure i know) require that coolant have some ingredents for sure and not have others. Or you can read the manual and then get one from a local store that does not have the prohibited ingredients, like i said i had this problem with my TL and had to buy acura fluid which was like 15$
