OldGuyDIY $16 20 Minute Replace Tractor Thermostat 1985 Kubota L2550 Running Warm After 4 Hr Tilling

This is a hands-on DIY repair video on a 1985 Kubota L2550 that ran warm after four hours of tilling. The owner removes side panels, pulls the old thermostat, compares it against a $16 Amazon replacement versus the $38 dealer part, explains why he skips the included gasket in favor of Ultra Black sealant, and discusses test-running and temperature checks afterward. Best for owners troubleshooting overheating or doing this exact repair themselves.
