Can anyone help?? The cooling metal header pipe which runs up the right hand side of the block has real bad corrosion under a plastic clip which secures another cooling system pipe to it. The metal pipe is very badly corroded and starting to weep coolant. The pipe as stated earlier runs along side the engine block on the right hand side but as you follow it down it does a 90 degree left inbetween the radiator and the engine. This pipe needs replacing and I can do the job myself but wanted to have an understanding of where the pipe goes and what it's connected too before starting if you know what I mean?! Does anyone know of a schematic diagram for the AJT model engine?
