Lx565 water pump

How do you if your water pump is bad on a lx565 skid loader? She want to overheat and I replaced the fan belt. Im not a mechanic but with some guidance I have had good luck. Any help would be great.

Make sure radiator is clean also I would try a new thermostat.

How do you know the water pump is the problem??? You could have a stuck thermostat or a plugged radiator. It might even have blown a head gasket.

Run it and see if the radiator hose above the thrmostat is getting hot. If not then change the thermostat. Much cheaper and easier then a water pump.

Then run the engine with the radiator cap off and see if the water is moving. If it is then the water pump is fine and the radiator is plugged. If not then it MIGHT be the water pump.

Also run it and see if you see any bubbles in the radiator when it is running. If you do then you have a blown head casket or cracked head.

So you need to spend some time finding the true problem rather than just throwing parts at it.

If the pump is not leaking out the weep hole and the bearing is tight the water pump is probably not your problem.I just changed one that had 12,000 hours on it and it was leaking ,not heating. There have been thousands of water pumps changed on equipment to cure a heating problem and it didn't fix the problem. Check for plugged radiator,inside and out,restricted air flow,stuck thermostat,collapsed radiator hose, check the coolant level and see if it is circulating. Could be a cracked head, blown head gasket. Sorry if your are more confused than ever. Just don't jump to conclusions.Did the problem start all at once or did it build up over time? Good Luck

Where to start................
First of all... How do you know it's hot? THe display? Is it pushing coolant out? Have you checked the head temperature with an IR heat gun?
Just because the diplay squeals at you or gives you a shutdown doesn't mean it's really hot...
If you're getting erratic temperature changes on the display I would suspect the wiring first before the actual temperature.
Beyond that I would check the belt tension. Pull the rad clear of the cooler and really get in there with high flow air and BLOW the crap out. Then I would probably drain the cooling system and run a bottle of commercial cooling system flush through as directed and pull the lower rad hose and backflush again and again until it runs clear with no suds...

The short answer to your question is that if the water pump is bad... it will probably be loose at the bearing and the fan blade will have noticable movement... and when they get really bad the seal will leak and you will see drainage from the weep hole in the front of the pump housing as a result. One that is just starting to go will often not leave a puddle of coolant as it will evaporate on the engine front cover and just leave a green tracer running down the cover from the drain hole.
So... verify the temperature with a heat gun... then proceed through checking the belt (as they do eat belts up), blowing the rad clean, flushing the cooling system... and then you can start looking at bad thermostat or a pressurised system from a bad head gasket.
