I have a 320bl excavator with a 3066 Mitsubishi engine I replaced it with 3 different 3116 engines but all overheats,gave it a bigger water tank and fan blade but it still overheats I want to replace the engine with a different one apart from the 3066 and 3116 I learnt Cummins engine can fit into it Anyone with an idea about it Please help a brother out
If all these engines overheat, wouldn't you want to look for a common denominator. Radiator, pumps, coolers, something?
I know this sounds silly but did you change temp gauge and sending unit. I like to back it up with a mechanical gauge. Use a temp gun to check radiator and hydraulic oil cooler.
