I am removing my EGR valve and I know that I will have to plug a water port (either with a backing plate or by tapping the port and plugging it).
Does this mean that at some point coolent will start leaking out while I am removing the EGR valve?
If so, does it occur when the EGR is unbolted from the EGR mounting base, or when the EGR mounting base is unbolted from the block?
Should I plan on loosing a lot of coolant or does it just drizzle out.
As best that I can remember when I ditched this valve many years ago. Expect to loose a lot of coolant as it is the lowest part of the block. And unless you have a blanking plate with gasket made up first, you are best to either drop the coolant or catch it while you do the removal. The EGR valve has 2 different diameter bolts so the blanking plate must be made with that in mind.
