Jack front end of car up and put on jack stands as high as you can.I think you can open the cap (when cold of course) and run car.Watch as air bubbles pop up and make sure you can see the fluid flowing.

cap off, heater on full, start car, wait till air bubbles stop. done.

there is another way too

there is a bleeder screw near the water neck on the exhaust side of the motor. it's a 10 mm bolt. i know of some people that.. take the cap off. turn their heater on full with the car not running. undo the bleeder. pour fluid in till it comes out the bleeder and screw it in once fluid comes out.

for really stubborn ka's i've done the 1st one, but i've cut the bottom off of a soda bottle. made a seal with electrical tape and the bottle up-side-down where the radiator cap goes. what this does is allow me to pour more fluid in and have the highest point of the system where the radiator cap it.

Jack Front of car up if possible put catch pan down

1. Fill coolant reservoir

2. Take off radiator/coolant cap

3. Fill Radiator with coolant

4. Start Car with heater temp and fan on highest setting

5. Let run until Thermostat opens <idle will probably slow down when it does open> (which will probably take about 10 - 15 minutes depending on how hot your vehicle operates at)

6. Keep filling radiator if level goes down

7. Watch for bubbles after a couple minutes of thermostat being open and bubbles stop and radiator is still full

8. Turn vehicle off

9. Let radiator cool

10. Replace radiator cap

Finished...good luck
