And oddly enough, it's what's described in the owners manual! who would have thought that the manufacturer would do it right?

Late owner's manual

took a quick glance, looks like it says, remove the drain plug

bjzorn

do you mean remove the bleeder screw on top of the water neck? Thats they way I was taught a long time ago.

That's the first step in getting the air out. Elevating the front of the car helps too. I tried Bruce Arn's method; low pressure w/an air hose, that worked great. I also tried another method I saw on RL a coupla weeks ago; clean off the reservoir tank where the cap screws on and blow into it. Doesn't take much pressure to force the air bubble out of the rear of the head. Remember: BLOW, DON'T SUCK!!!!!
Anti freeze is hard on your kidneys.

Yes, cracking the bleeder nipple as you fill the coolant will greatly help in the final bleeding of the system, versus keeping it closed while filling, then starting the car and trying to crack the nipple as the car warms up (takes a lot longer to get the air out).

I also prefer the mouth-to-mouth method myself. Works every time. Just remember to squeeze off the overflow hose when doing it.

I guess everybody is afraid to suggest that method for fear of someone lapping up some anti-freeze and croaking.

Yes, if you pull out the overflow hose and clean it, you can blow through that. Hold your hand over the water neck to seal it (the cap won't do.) It's great to blow out all that air before startup, then you can just give it a little burp when it's warmed up and you are driving around. I prefer this to trying to bleed all the air out after getting the engine hot, and it's way faster.

Yeah, in the past, I've just cracked the bleed screw instead of completely removed it. I've never had it done so easily in my life on either car! eh, I'm happy.

Who reads instructions!!!!!!That's a waste of time.

My car doesn't have a bleeder on the coolant elbow on the head. I attach an old water hose to coolant pipe and back fill the motor from there. I fill up the hose from the radiator and connect it.

Never had a problem doing it this way in half a dozen fills. No bleeding, no apparent air bubbles.

Reimu

Blow into it, no use having to make everything difficult. I had been trying all the other methods and it still had air, so after thinking "hmm, I bet this would work" the blow method took a couple of minutes and it was done. Mentioned it on rennlist and got yelled at, go figure lol.

jbob

sorry - not completely following on the blow technique, do i loosen the bleeder screw and blow into the reservoir? thanks

Calmchaos

yeah you got it. I personally always take the bleeder screw all the way out.
If you don't at least loosen the screw your head will probably just explode.

Gorsh, who woulda thunk it I would have gotten it right without reading either the owners manual in the glove box, or the factory service manual on the bench....

In June I tore down and put her back together, and in the mix replaced all the hoses and the radiator, re serviced with Authentic Porsche GL-12?? (blueish) and while adding the distilled I cracked the bleeder valve, and kept adding water slightly more than 1 gallon) until it came out through the bleeder...

took me a while, but eventually it came out, and have maintained the first mark on the temp gauge during the last 4000 miles or so.... guess I got it right, and I didn't even need my hooked on phonics system to assist me in doing it WOOO HOOO
