Hi folks, I have a unique problem but maybe just maybe someone has an idea. Last year I bought a car aircon refill kit, the ezchill type inc hose, gauge, trigger, cylinder. All fine and system was working after I used it. But, since then the pressure in the system although up, but I think it's low in actual coolant so it has lessened in effect. Now then... bear with me... I was going to vent the pressure from the system with the kit hose (safely) but find that when I try to remove the hose from the refill cylinder the cylinder fails to reseal so I have to leave them together. So I cant use the hose with it's much needed connector. Also when I come to refill the system, I want to make sure a good amount of coolant passes from the cylinder to the system so should I hold it upside down for longer in case I'm just putting pressure in and not the coolant. Not sure of the cylinders' inside see! Anyways, hope you can help! TIA.

Only the most ardent DIYer would mess with a car's aircon when garages have specialist equipment to do the job in 30 mins for about 60 quid.

Sorry - can't answer your query!

I am a mechanical engineer so these tasks are a doddle, but I can't find any info on the cyl which would solve the coolant and how it expels from it. I could vent the system manually if I need. A garage did look at this and suggested the home kit as it's all they use anyways. Just hoped someone knows. I've posted on car forums too.

Not venting as it's illegal, pointed out by a car forum. Garage job :(
//so these tasks are a doddle//

The evidence would point otherwise.

Just pay someone with the right equipment like everyone else.
