Coolant change/ part of service.

[Ped]

Hi, I just wanted to know about doing a full coolant flush myself and the difficulties/lack of doing so. Is it just a case of opening the lowest plug (Bottom of Rad) aswell as removing the rad cap to let the system drain then replacing lower plug and filling. How to prevent air blocks or anything?

When drained, refill the rad to the top. Start engine with rad cap off, keep squeezing the rad hoses to burp the system. Keep filling coolant to the top and keep squeezing to see the bubbles come out. Simple!
