Hi Everyone,

I've finally decided to replace my upper Rad Hose , now the hose im getting is from Rockauto from GATES, which is said to be a good brand.

now i think it would be a good idea to buy 2x new clamps too ?

Also guys im changing my oil myself this time so
im buying 4.92L of Mobil 1 synthetic Oil
and a Mobil 1 Filter which is like $15 each on rockauto

Hopefully i do this right

but i dont know which one too pick , Only two options on Rockauto

DORMAN Part # 13400 Corbin Clamp Assortment, 3/8", 1/2", 9/16", 5/8"
Part ImageNext Image
CAD$2.86

DORMAN Part # 55173 Size 17/32, 3/8, 1/2, 5/8, 9/16 Universal

Thank you

 

Also i hope i dont look stupid but the Oil is 5w30 for a G37x Coupe and 4.92L or 5.2 Quarts ?

 

I don't know the correct size off the top of my head, but none of those clamps you listed are large enough for the upper radiator hose. Lots of people just end up going with a simple worm-gear type hose clamp, but if you can find a properly sized Corbin-type clamp, they are definitely superior.

Also, wasn't sure if that was a question or not in your last post, but in case it was: Yes, it's 5W-30 and 5.2 quarts.
