so you deal with the customers too? Yall sound like you never talk with your customers, if you want clarity, discuss it. If you take a job in and they got a quote are you just gonna do it without discussing anything with them?? Plus, have you even seen what it says on their site? Here is what it says on a water pump.
Best Practices
When replacing the water pump, the drive belts and/or timing belt may need to be removed. The belts should be replaced if they show signs of wear or coolant damage.
The entire cooling system—including all the coolant hoses and fittings, radiator, coolant fan(s), and fan clutch (if equipped)—should be inspected when replacing the water pump.
To help prevent future issues, we recommend replacing the thermostat when the cooling system has been opened for repairs (e.g. water pump or radiator replacement) or during a system flush.
Common Symptoms
Water pumps require replacement if they begin to leak coolant or become noisy. Leaking water pumps can result in damage to the drive and timing belts.
A failed water pump can be caused by problems in the cooling system, such as a failing thermostat, radiator, or head gasket.
So, it seems to me you just need to talk with your customers, we do and dont have problems, we are also priced to be within their ranges, if you want to price your repairs out of their range then thats your business.
