Post by: CROSSBOLT on March 31, 2022, 02:50:34 PM: How do you know it overheated? What did it do when it overheated? How many hours/miles? What is coolant level in overflow jug and radiator? Can you smell antifreeze or see any leaks? What color is the antifreeze coolant?

Post by: CROSSBOLT on March 31, 2022, 10:08:24 PM: We need a starting point in trying to trouble shoot by remote control. Please answer some questions:
In addition to the ones already asked, what indicated overheating? Then how did he determine it was out of oil?
What does it mean it has been "good since refilling with oil" but it won't start?

hmmm....I'm no engine expert, but this doesn't bode well for the machine..overheating plus no oil? Was the machine new to him or has he had it for a while?
