    hey all

    i have a question about my radiator it goes like this

    my motor sits about an inch or more higher than my radiator so im guessing it wont feed the coolant thirsty motor so....
    1.will it flow?
    2.will i have to make a tank of to the side the same hight as my motor to get it to feed the motor easy enough?
    3.any other ideas?

    cheers jarrad

    The height difference is not a problem once things get going. It will flow, because you have a water pump. Everything is under pressure, the pump does its job, gavity has little effect.

    The problem is, when you fill the motor, you need to get all the air out of it. If the rad cap is not at the top of the system, you need to put a tap or bleed nipple at the highest point.

    making a swirl pot could be your solution here, cheap and 100% effective.

    Or just jack up the front of the car high when you fill it up... problem solved.

    golbeg, you still want an air bubble to form in the radiator before the head. This is why VL heads crack all the time

    go the remote filling point

    second that there is 1 you can get with a little filter element in there that will help you out alot works a treat on the VLs
    the dyno pull to 300rwkw

    BT20v is making 300rwkw like i said i would without nitrous so now its time for some spray and see if she will run a 10s or less

    you wouldnt need a filter in a cooling system, in fact it could do more harm then good. If it blocked up which it would since the cooling syst is hardly a clean environment. then it would restrict flow and cause overheating issues. no need for a filter IMO

    I was asking because the comment was used in the original context of talking about coolant bleeding. If its just for filtration I dont see the point
