"Hi guys I'm back again. I have a LM318 which has behaved normally in the cooling system up until now. The motor has a closed cooling system using normal coolant.
The boat is on a mooring about 140 miles from home so I only get to it every second weekend religiously.
On arrival I immediately check fluid levels etc etc. The last two trips I have found the cooling system to be fully pressurised, and when taking the cap off, coolant sprays out over the motor even though it is cold ( ambient temp about 25 degrees ( centigrade ) and two weeks since the boat has been used.
How can this be ? and why does it occur now and not in the past ? Has anyone had a similar experience or able to offer me some advice.
Any and all replies will be sincerely appreciated."
