Hi All, Who has this engine and in particular this thermostat setup? My issues was the engine not heating the water, has been fine the last 8 months. Issue cam about when the Bowman end cap on the heat exchanged split, sending coolent everywhere. Replaced and refilled with coolent and bled system and still not hot water. Moved on to checking the thermostat, taking the cover off i was met with a weird hard plastic or possible rubber that has aged in hot water, it came out but very misshaped. Tested thermosat with good old pan of water, opened as it should in hot water. Bought a new one for a perkins 104-19 engine, plus sourced a spring that after researching the engine was listed. On fitting said spring to me it was not strong enough and that the water pressure could just move the whole thermosat in situ...anyway fitted with new thermo, spring etc and still not hot water. Im thinking that perhaps the hard tube is the way to go, buy a piece that attaches to back of plate and outside of thermosat, then drill 3 holes like the old one. I do not know engine temp and gauage broken and dont have testing equipment. I know if i run engine for two hours and take rad cap off the water is luke warm. So i preseum water is just going round the engine and calorifier in one big loop and never getting hot. If i run the Alde boiler the water does heat up so I know the calorifier tnk is OK. Would welcome thoughts and help, many thanks.
