I don't understand the coolant bleeder/tank system

Yes the cooling system is a little odd. Crazy Germans. Remember that Porsche has been building air cooled motors for over 60 years and the 986/996 is essentially a first generation water cooled flat six production motor so we are guinea pigs to some extent. Chevy has been doing water cooled motors since 1914?? so by now they have the bugs worked out.

Do pay attention to purging all the air out as air entrapment and hot spots in this motor mean cracked heads or worse.

I guess what I'm really asking is how big of a compressor and tank do I need to run this. Mine's kinda small - great for filling tires and blowing off dust but not adequate for most air tools.

I've seen people run them off rather small portable compressors, so it can't require all that much. Other than the recommendation for 90 psig, I'm not aware of any other requirements. You may want to drop them an email as I'm sure this question comes up all the time........

I borrowed a small 8 gallon unit, and it pulled the required vacuum no problem. A smaller one would likely work too, just would take longer to evacuate.

RR, I live in a city with a pop of about 700K. Just Googled tool rental and found 18 places I could rent a compressor at a fair price. I looks like your in the UK and would think there it would be about the same. You might find someone who has a compressor but no bleeder and do a loan.

I use a 6 gal pancake compressor and a UView. I think that is probably the smallest you could go. I did 2 Distilled water flushes and then filled with 50/50 pink stuff
I felt like I had to run the purge valve a couple cooling cycles anyways as I was not familiar with the temp behavior after this and new WP and low temp thermo replace.

The hardest part here in NJ is getting rid of the stuff, 12 gallons. Auto parts stores don't take it. Finally had a House hold recycling day where the county takes things like paint and antifreeze

I would like to know better how one uses the Uview with a full system to help remove any potential trapped air.
Anyone done Vacuum on a full system???
I have just started seeing condensation under trunk lid and I had a drop or 2 come out the overflow after driving an hour and half. It's been 4-5k miles since all the coolant work with no issues. Temps run cool
I have a new tank as of last Dec (2015),WP, thermo Flush. I had put an '04' cap on 3 years ago.
I just order a new cap to see if that is it
