This year whilst winterising the engine I noticed the engine struggled to pull up the antifreeze mix from a 5litre water bottle. I made a temporary seal around the neck of the bottle which made some difference.
I have spoken with Bukh in Poole and they were very helpful suggesting that the pump may need an overhaul as they would expect the coolant to be pulled through fairly effortlessly.
My previous posts on the forum demonstrate my concern that we have been overheating with more steam than normal. I know Bukh's steam but I think it has been increasing.
Any thoughts re spending money on a revamp or a buy new?
I believe it will cost around £150-180 for servicing existing and for similar money get new one.
I have had the gas poker out and cleaned area, manifold off and no blockages including the water pipe from the thermostat to exhaust. So zeroing in on pump as it was sluggish.
Your thoughts appreciated.
