You will note that in my above image I have removed the first two injectors. This is because this car is a Japanese specced RHD car with a NipponDenso air con compressor fitted. The routing of the AC cables made it impossible to undo the top W.P.inner bolt and extremely hard to tighten the lower bolt as per the DIY instructions. I had to use a spanner between the 1st and 2nd pot inlet manifold to inch the bolt out.

Even then the replacement process wasn't so successful. Ultimately I completely removed the inlet manifold to get this water pump water tight. P.I.T.Ask
