How to tell if the waterpump is faulty

Hi Charlene:
A faulty water pump will usually give you some indications.
1) Look for a coolant leak. Not always evident
2) Grasp the fan and see if it will wobble. A bad bearing can happen without the seal leaking.
3) Rattling sound could come from alternator, air conditioning compressor, tension idler, or power steering.
Use a mechanics stethescope or dowel sound rod to CAREFULLY listen to the different parts with the engine running. You will hear the faulty part.

Over heating

Common causes for over heating are listed below:
  1. Lack of coolant
  2. Leaking radiator (usually on a seam)
  3. Leaking coolant line (usually but not always around the fitting)
  4. Bad thermostat - prevents sufficient coolant from entering the system from the reservoir
  5. Bad waterpump (will usually leak but not always, can be bad waterpump bearing)

How can i tell if the water pump is working on a 1997 honda odessey already changed the thermastat

this is a tough one, the waterpump on these engines is to the rear of the engine with its on belt that runs off the rear of the cam. i have seen these waterpump impellers break apart and then the coolant wont circulate and inturn iit overheats,i guess you would need to remove the pump for a good look at it. if you are having an overheating problem and the fans work then i would look at the pump. another test to see if pump is working is to start the engine and keep feeling the top and bottom hoses both should get hot after a while then you can say pump is working but if the bottom hose is warm and it runs hot then i would look at waterpump. good day.

When i start the jimmy i smell antifreeze, is it the heatercore or the waterpump

may be either, Is your passenger floor wet? does the heat work? is there a film on the windows?(these are tell tale signs of a bad heater core) is there steam rising from under the hood? does the temperature rise and fall? is the antifreeze a brown color(sign of broken impeller) or is there a loud bearing noise? (these are signs of a bad waterpump)...are there any other symptoms?

My car keeps over heating and i dont have heat

The first thing is to check the coolant level, make sure engine is cold beefore removing the radiator cap, then start car with cap off and add as much as needed, this problem is not a bad thermostant, a bad thermostant would overhaet but would give heat, even if it was stuck open the heat would take while to get hot but then car wouldnt overheat, this problem one one of these problems, . low coolant or a bad waterpump, i have seen a few like this and the waterpump propeller rots away and coolant cant circulate, the last thought would be a bad head gasket but you would get heat when driving, so if coolant isnt low then waterpump is bad. hope this is helpful.

I recently had to replace the headgasket on my 93 honda accord. I replaced the waterpump and timing belt/balance shaft belt a little while back. I had the head checked and installed everything back. And...

funny noises are hard to tell and discribe,could be the waterpump noise or a belt noise, or just the starter wine, you really need someone to listen while you start the car to help pinpoint the area

Overheats in town driving or at idle. radiator waterpump thermostadt bigger fan replaced no help. worked fine before emitions recall.

Sounds like it could be timing, cracked head, bad head gasket, or any combo of the above. Easy way to tell is to remove the radiator cap, start it up, and watch and see if there are bubbles present in the coolant. If so, you have a bad head or head gasket.
