Re: cooling system

No comment on acid cleaning the cooling system other than to say "I use
Kleenflo Radiator Flush" only!  I've replaced too many copper seals with
anything else - PS Some engine adatives will also dissolve copper!

Try again with the throttle open wide. Should be a minimum of 140 assuming
the engine is in good shape. But the number doesn't matter - what really
matters is that all four cylinders are within 5% of each other overall. My
spec book indicates a range of 130 (LC) -  165 (HC) for the 1147 engine But
doesn't indicate a 'normal' Mine is consistently 145+- 3 psi
