DIY: Bleeding cooling system
Morgan 29 May 2011
Using Alex's step by step guide, I have bled my cooling system.
Usually, if air is getting in, there is a leak of some kind. Check for this around the engine bay. The bubbles appeared in mine after I rinsed out the engine bay so the coolant level was still high and there are no leaks, fortunately.
Thought I'd chuck up a pictorial guide for others who may hear the bubbling waterfall behind their dash.
Plus, this place needs more DIYs!
Make sure you have a friend to help you
Park the car on an upwards slope
Take radiator cap off and block overflow tank. I used a G-clamp
Start car
Warm up the engine. Rev at 3000rpm until fans kick in

Turn A/C to max heat
Top up coolant. Water can be used to do this. Repeat this for a few fan cycles.
Put cap back on and take off the clamp
Drive car
Let car cool down
Keep an eye on the coolant level and top up when needed.

How do you know that you have bubbles in the coolant but? Is it a loud noise?

Cool DIY morgz.

You'll know it if you hear it, used to happen in my old gen 2 but I had no idea what was doing it
Nice writeup Morgan!

Nice going.

Nice write-up though Morgstein.

But it took be about 15-20 mins to bleed this out including taking photos. It doesn't cost you anything so I don't know why you wouldn't do it!

AFAIK it just means there are pockets of air running through your cooling system. This may give your temp gauge a false reading?

Eh I've just been so busy lately.. If I'm not at school, I work Saturdays and Sundays.. So many other things to do on top of that.
Maybe after school one day this week, hopefully

Very nice write-up
Why wouldn't it is more the question.Hey guys just wondering will this work for turbo models as well?? (more to the piont, B4's)
Thanks

In my research before doing the bleed, I found some that did put the heater on and some that didn't.

A safe bet with all cars is heater on max temp and low fan (so you can feel the heat).

Always better to be safe and really it is no extra trouble to do it
Once again, great effort Morgan! good to see some usefull DIY stuff appearing.

I have a special tool that can be bought from repco or any autoshop that sits on where the radiator cap goes, and holds a head of coolant. As when the air pockets come out, it sucks more coolant in.
On N/A models, use your only radiator cap which is on the radiator,
Turbo models, use your header tank one if you have duel caps, as its the highest point, unless your parked on a huge angle or on stands

Me too.Surprisingly I actually havn't seen that tool. sounds like it could be a bit of win. Who makes it? I wanna get one.
My home made one is p00.
