Hi, first and foremost, english is my second language so i might write weird sh * t. bear with me :) I have a problem with cooling system. It's NOT overheating, it's the opposite... It's allways with 2 "lines", sometimes 3 but only on intersections. From what i know there are two "circuits" for coolant to take, small one and big one with radiator. It looks like it allways use big circuit and with temp 4-10*C (40*F ?) it never reach engine normal work temp. It might not be a problem in summer but not it is. What should change to get it work as it should ?
