Bleeding Radiator

[hmong_Spec]

i got a 1995 integra. thinking about bleeding the radiator. i heard that you can leave the cap on, and leave the reservoir full and the air will bleed itself out. or do i have to take off the cap, start the car, than the air will bleed itself out, and add coolant.

cap off car on run till the fan turns on or about 5-10 minutesor no more bubbles come out.

Yup. Might get a little messy if it does have air. Try fixating a funnel on the filler neck to catch overflow and add coolant as needed. Lisle makes a funnel for this exact purpose, but you don't really need it...
