I would start by dropping the bottom radiator hose and flush out any old coolant from the block that way. Sometimes there is a blanking off plug that looks like the head of a bolt on the side of the block but you need to be careful undoing this as it might break off and leave you with an issue to fix.

toxcolin:
Thanks for getting back to me that's great. Is the bottom radiator hose attached to the heat exchanger? Sorry if this is a supid question.

cobbadog:
It is not a silly question, the only silly question is the one you dont ask and it turns bad.
To answer your question I am not familiar with your model engine so with out a pic I cannnot say.
Is this a marine engine?
May I also suggest that you do a Google search for a workshop manual for your engine. There are free ones out there to be found like I did for my little SR2 engine. This will help you out a lot with servicing and any other specifications you may need. There may even be a manual on this Forum so maybe use the 'search' bar and see what turns up.

toxcolin:
Thanks again for the reply.

The workshop manual unfortunately has no diagrams and nether does the parts manual for the bottom hose. I can see what a bottom hose looks like on ebay for the LPWS4 so im hoping i can scrabble around to find it.
