Coolant leak TB42

[Bigrig]

There is a plate located on the RHS rear of the block just below the head,it leads in to a water jacket.It looks like you need to pull the inlet manifold off to get to all the bolts.I found the easy way is to pull the starter motor off and you do it from underneath.
Not sure if this helpful for anyone,but it took me a few beers and thinking time to work it out.

Thanks mate - top tip!!
