Default Frickin' air bubbles

Well, I changed my coolant today. Got the crap scared out of me. Despite following all the posts and directions, when I was done I ruined my plans for the rest of the day.

After I was done I was driving all of about 3 miles when the car suddenly overheated. 5 bars in MY03.

Trouble is, I live on a 1700 ft hill. So I coasted down before it overheated. But it took me over an hour to get back up the hill cause I could only go a hundred yards or so back up the hill before I'd hit 4-5 bars again. Took forever to get home.

After I got home I did the bleading/purging procedure again about 4 times before I got all the air out and the heater was blowing hot air again.

Lesson learned: never try to shorcut stuff.

I've had to bleed mine several times recently. Here's how I do it (has worked everytime)

- Jack up front of car

- Make sure radiator is full and overflow tank is at high level

- Re-cap radiator

- Crack open bleeder valve on intake manifold

- Squeeze upper radiator hose until liquid comes out of bleeder valve, then
immediately close bleeder valve (while maintaining pressure on rad hose)

- Top off radiator with fluid, cap and repeat until no air comes out

- Now do the same process, but use the rear bleeder (on the firewall)


Hope that helps
Scott-

^ sweeet!! your method can be very useful during coolant flush also.
this way people dont have to bother with overheating after the flush.
