hello guys ,
i just bought a used 2012 g37 sedan journey trim , i'm loving the car so far but i have some questions , my left wheel bearing is failing so i'm going to replace it soon should i replace both of the wheel bearing ?
another thing i need to flush the coolant water how much liters does the g37 take ?
there is a weird thing happening when shifting from 4th to 5th gear i googled it and they call it a transmission flare is there anyway to fix it ? plus i have some rough shifts and downshifts ,
the previous owner said he changed the transmission fluid but not with the oem specific fluid which is matic s so is that the cause of my transmission problems?
my left high beam light isn't working for some reason is there anyway to know what's wrong with it ?
my ac doesn't work how could i know if the compressor is faulty or it's a leak ?

 

Omar, how many miles on your G? If it's over 100k miles that other wheel bearing would be a good idea too.

Coolant req'd is about 1.5 gallons and I recommend a Lisle No-spill funnel kit or similar product, here's a good DIY video

Transmission may need a software update, the dealer should be able to look up your VIN# and see if it has the latest updates, that should help but that "flare" is a typical issue.

I changed my ATF w/ Valvoline Maxlife Matic S compatible fluid back in June 2015 and has been performing well. If your transmission was serviced properly that ATF should be fine.

A/C & headlight is something you need to take to a shop, too many possibilities there.

Good Luck!

 

If you find out you need a new compressor PM me. I have a good working one off my parts car.

 

There may be a loose wire in the headlight, but that's just me. Bring it to an auto shop and get it checked out.
