I have just changed the turbos on my fd with another set of stock turbo but after putting it all back together it overheated straight away. I think it is simply air trapped in the system. Are there any bleed valves on any of the pipes and if so where.Thanks for your help.

search next time before you get flamed!

 

It shouldn't overheat due to an air pocket. However, the pocket could cause abnormally high coolant readings. It will often beep because the coolant level sensor detects low coolant, but fortunately that does not mean you're overheated.

Burp the system (reach down in front of the filler neck, and give the upper rad hose a squeeze) and keep refilling it until there is always coolant nearly to the top.

a good sized air pocket will def cause an overheat if you let it

 

Did you disconnect the TB coolant hose while you filled up your coolant?
