- ACTIVE: JDX730 DAYS GONE BY: JD3010, JD790, JD425
I own a '93 JD425 with Engine: FD620D K-Series. Starting to have issues with overheating with the temps in the low 80s here in NH. The engine is clean, checked air filter, radiator blown-out, radiator full with proper coolant, screen cleaned...? The engine is really getting hot (but the temp gauge reads normal) then the engine starts to skip and when I turn it off, I really have to let it sit a good hour before even attempting to re-start...... When I squeeze the lower radiator hose going to the Water Pump, no sound of liquid so.....perhaps the Thermostat or better yet Water Pump is the issue, maybe yes or maybe no..... :confused3:
Thinking it might be the Thermostat and :reading: reading other blogs, people write the old thermostat was rated for 160 degrees, now there's this chatter the gov't stepped in and made JD change it's design to run hotter at 180 degrees (anti-pollution). Apparently the hotter spec runs fine in later models but early ones (like my work horse) and carburation design not-so-good..... Then some out there who cite AutoZone has a 160 degree thermostat PN # 7203-160 that fits...and reading further, maybe I don't even need a thermostat at all since I store it during the winter after the last grass cut.
Comments welcome... THANK YOU !!
