Technical 500 twinair water coolant bleeding help

[zunkus]

I own a 2014 500 Twinair which I've bought new. I had issues with a cracked reservoir which was solved with a new (from ebay) expansion tank. I have had air trapped in the water system ever since though. I couldn't find any air vent plugs on this car to help me do this so resorted to fitting a water bottle on top of the reservoir so as to overfill it, start the engine with the heater on, and rev it after it got to running temperature. This seemed to solve the issue for a while but now that the outside air has gotten hotter and am using the aircon more the issue has resurfaced. I hear a gurgling and splashing sound from the passenger side (It's right-hand drive). Any help on this please?

For most warranty claims on car parts they need to be installed by a vat registed garage and euros are known for trying to get out of paying

No they dont, I've returned a few parts to our local motorfactor and they always replaced or refunded if in warranty.
You buy a part, not how it's fit.

It does help if you are a regular customer and depends on the managers "policy".

If it's only when the ac is on stick you head under dash and listen when was the ac recharged?

If you are sure it is air in the cooling system and no other issues, some garages have a tool that evacuates the system then refills from a container with coolant/antifreeze mix, thus no air just coolant, I seem to recall it runs off a reglated air supply and a three way tap and reservoir. To be honest I have never needed one and I think they were designed to speed up refilling and bleeding process more than anything else.
As John202020 says noise could be aircon fault.

In all fairness I probably did over tighten it! I don’t know my own strength sometimes… it’s prob why the rear bleed screw went on me too a few months back .. but that was a 2011 part so who knows!

On anything to do with liquid, I use some Blue Hylomar or similar gasket sealant on the threads of any screw.

Not tooooo much since you need to be able to dismantle it without getting the angle grinder out... but it helps to bind the threads, so you can do them up slightly less tight than you might, if you were worried that they'll unscrew themselves.
