My neighbor has a 553 skid steer and it overheated on him, not sure how hot it got. The thermostat stuck and he replaced it so the cooling is ok now but it starts ard when it is cold. He said he replaced all the glow plugs last fall and thinks that maybe they are burnt out from the overheating issue. Could this be his problem? The engine is a Kubota V1902B. Thanks

Ran into the same problem with one of the small Kubotas a couple of years back. In that case it wouldn't start hot or cold. So, in answer to your question, yes, it could be glow plugs, but that is easy to check. First check to insure they are getting voltage so they can work. If they are you can pull them and put a hot wire to the plug and then, holding it near the plug (cold end), ground the body and see if the other end gets hot. If each one gets hot and they are getting power to them then it's easy to either say yes, nonworking glow plugs are the problem, or it's time to start looking for some other problem.

i have 2 L455s with the kubota engine. one of them is much harder on glow plugs for some reason, as in changing 2 of 3 plugs within a year. you can get an idea of the glow plug's condition w/o taking them out by unhooking the wire to each and checking continuity from the plug post to the engine block. if its burned out you won't have continuity.

Wayne is right on checking the glow plugs but more than likely when he ran it hot, has some ring dammage. Compresion is on the low side , will make the use of glow plugs a have to thing.
Check the plugs, get them right then if it continues look at compresion.
