I have a 2004 gsxr 750 and it keeps over heating. It'll over heat within 10 min of turning the bike on. I've checked the following:

Thermostat opens up at the right temp
ECT Sensor is reading the right resistance
Bled and burped the radiator so there is no air in it
Radiator is not blocked checked that already
Checked my plugs to see if I'm running lean which I am not
Checked radiator cap to see if it's holding correct pressure which it is


The last thing I can think of is a failed water pump or I have a leak somewhere. I am going to pressure test the entire coolant system. How do I check if my water pump is running correctly?

Thanks.

 

You may be able to use a similar strategy as this one when it comes to testing for the water pump.

You can also check to see if something is awry with the water pump by seeing if there is any shaft play.

 

did u check to see if the fan is coming on?
