I want to install an overflow tank i got cause my oem on had a hole in it and the aftermarket one was cheaper and looks better.

what i wanted to know if how do i know how much i need to fill the aftermarket overflow tank? its smaller then the oem one and has no markings on it?? thanks

 

Fill the stock tank to the proper level and then pour it into the new tank...simple.

 

about 2 seconds after i made the thread i figured that out lol! thanks
