How to get a air bubble out of a 240sx "sticky"
i get a ton of calls on this subject matter so here is the quick and eazy fix.
wait till engine is cool first
take a jack lift the front slightly.
take radiator cap out.
take bleed screw off
take a 2 liter pepsi bottle cut it in half
take some black electrical tape and wrap the bottle neck a little
flip it around and place the bottle neck were the radiator cap was at.
have somebody start the car
turn on the heater
now start filling it with coolant
close bleed screw after you get a nice even stream of coolant
add antifreeze until you over fill the rad by a quart
let the engine run after 3 minutes the thermostat will open and suck in the exess antifreeze
fill it again but with about a half of quart.
let it run until no more bubbles come out.
replace cap and enjoy
if problem continues and its a single cam. there is a good chance that the timing chain rubbed up against the timing cover. which will cut a hole into the water outlet.
it take alot for a dual cam to do this.
