does anyone know if i really have to drain the radiator fluid to install my plenum spacer.. im a new g35 coupe owner.. dont know much about my car just yet..

 

no you don't have to drain your rad to install a plenum spacer. . .

might be a good idea to have someone else that's a little more mechanically inclined to do it for you/show you though. . .

just a thought. . .DOMO

 

ok.. i wuz just makin sure... i really didnt see the point in draining the rad... i've done bolt-ons on my prior cars.. but they were mostly honda's and acura's... any other tips though for the installation would be appreciated..

 

I used a second stock gasket to install mine instead of what the instructions recommended and have had no problems. The only issue I have is I did not put thread locker on the bolts and have to tighten them regularly. Also make wure you don't over tighten the bolts. I believe it is recommended to use a screw driver type handle (that accepts a socket) and hand tighten them with gloves on (I don't remember the torque specs. The gloves give you more grip and it would be hard to over tighten with hand strength only.
