plumbing problems
Anyone got any ideas of how to bleed the cooling system.
I am using an electric water pump which i can run with the engine off to circulate the water but i dont seem to get many bubbles coming out of the
header tank hardly any at all.
I am presuming i had an air lock after my disaster which ended up with the whole car being drenched in coolant. (not a good look)

Loosen the connection where the upper radiator hose enters the engine [there might also be a small threaded bleed screw there] as air rises to the
top of the cooling system and gets trapped, causing the cooling system to vapor lock. Allow the engine to run, with the heater on (fan can be off or
on low) until the thermostat opens and hopefully you may notice the hissing of air being purged from the system till a stream of coolent can be seen
to flow out. Be careful when resealing the hose as the coolant and any steam released by the system will be hot. Ensure the overflow bottle is filled
to the Max line.

There should be a bleed screw on the top of the radiator..
If you are using a polo rad, you may need to drill a hole on the plastic "extrusion" on the side near the top hose and stick a bolt in it
to make it a bleed screw..
Opinions are like backsides..
Everyone has one, nobody wants to hear it and only other peoples stink!

Its a good idea to bypass the pump controller to get maximum flow while filling & bleeding too

Yes i am using the polo rad and i locktited a bolt in the outlet near the top rad hose so i will hopefully be able to undo that and use that as
bleed.
Thanks guys.
