  • Guys. Is tis normal? There is tis big coolant hose which is connected to the top of the radiator. When I pressed it, i can see tat the coolant is flowing back to the reservoir as the coolant in the tank moves. Tis happened in both cold and hot engine. Is tis normal???

  • It's normal as pressure being applied. Nevertheless, check ur radiator pipes as they might need a change.
    A good tuning car must be something that you can take out to the streets.  The car must be fun, fast and safe on all kinds of road conditions.

  • Wat it got to do with the pipe??

    U mentioned "it's normal as pressure being applied". But when the engine is cold (no pressure in the coolant system), the coolant still can flow back.

    My understanding of the radiator cap is, it will hold up to 1.1kg/cm of presuure. If the pressure in the cooling system goes beyond tat, the valve will open allowing coolant to flow into the reservior tank. Correct me if i m wrong.
