Questioni have a Kawasaki 750 vulcan.. i spend a lot of time on my scooter, but i happened to go out of town for a couple days. while i was away my bother in law knocked her over while he was mowing the yard.
he never told me. anyway i got on and took off down the road, made it about a block and she started to cutout. couldnt figure it out so i pulled into a station and checked the fuel. was none. filled her up and tryed to start her, she wouldnt. she tryed but couldnt and i killed the battery doing it.
so a guy pulled in to see if i need help, we put her in his truck got her home and she sat. i found a guy would said he could get her to start, and he did. but since then she gets hot and blows her water out the overflow. he told me later in the week she needs a water pump. well i wasnt sure, so i checked the thermastat, replaced it, found the bleeder bolt broken off. i fixed that now im wondering, could the waterpump be out. and how hard will it be to replace in my yard. i havent tryed to start her yet, im charging the battery.
any help would be great.. thanks.
AnswerHi Geo,
I recommend you find a copy of the service manual and review the troubleshooting procedures. Determine if the water pump or other parts is defective. Once you know what is causing her to overheat, repair accordingly.
You should be able to perform the work at home. The only special tool I can think of is a tool to purge air from the cooling system. MityVac makes a tool for this. It's called the AirEvac. You can rent or borrow such tools from local car parts stores in most areas.
Cooling systems are designed to be air free. Air lowers the boiling point of coolant. Anytime the cooling system is opened, it must be purged of air.
Perform electrical diagnosis on the fan switch, thermo-sensor, and other related componets to verify their integrity.
