I HAVE A JD 320 LIQUID COOLED ENGINE THAT HAS SUDDENLY

Customer Question

I HAVE A JD 320 LIQUID COOLED ENGINE THAT HAS SUDDENLY STARTED RUNNING HOT. I SUSPECT A THERMOSTAT. HOW DIFFICULT IS IT TO REPLACE
JA: I'll do all I can to help. Tell me a bit more about what's going on so we can help you best.
Customer: ENGINE LIGHT COMES ON A FEW MINUTES AFTER STARTING TO MOW. IT CAN BE IMMEDIATELY COOLED DOWN BY RUNNING COLD WATER ON RADIATOR, BUT GETS HOT AGAIN IN ABOUT 2 MINUTES OF MOWING.
JA: Is there anything else the Small Engine Technician should be aware of?
Customer: NOT THAT I'M AWARE OFF. NEEDS TUNING AND WILL GET A NEW CARB. AT FIRST OPPORTUNITY.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Small Engine Technician about your situation and then connect you two.
