Engine rebuild woes

[Glenda Nelson]

After relacing nearly every reciprocating part in my well-worn TC xpag engine, we discovered, after machining for new sleeves, that the block is badly corroded and beyond repair (apparently not uncommon). I have owned 4195 for 17 years and have always used an engine coolant concentrate, mixing 1/3 to 2/3 water as directed.

The label states that the coolant consists of Ethylene Glycol 96% and corrosive inhibitors (does not qualify which are used), suitable for cast iron or aluminium. It always looked a lovely lime green colour in the radiator, but obviously did not work!

Can someone suggest a more efficient coolant/corrosive inhibitor?

Cheers
