Well ive noticed in a few pictures on this site that alot of people have crap load of coolant in there tanks(reservoir)..mine is half way when car is cooled down,where other peoples are almost full...which one is it?

 

you mean that little filler neck?

 

on the right side of the motor..the tank thats on the drivers side fender wall...overflow tank

 

its called the full when cold mark. thats where your coolant level should be if its over thats fine, its when it starts getting under that you want to start taking a look at everything.

 

cuz mine is usually always half of the tank..like where the top and bottom splits thats where my coolant level is...

 

yours is fine where it is...I keep mine over filled but it comes filled half way up from factory and like stated above it has a cold fill line on the tank

no that's the I/C coolant system and its separate.......
