i have a 1997 ford ranger 4cly 2.3 with engine noise the noise is a knocking/ticking sound. I had the tensioner and idle pulley replaced. and the power steering pump has also been replaced. the alternator is about one and half years old. the truck has 272,000 miles on it and the water pump has never been replaced. I just had the coolant outlet replaced and the thermostat replaced. I noticed on my temperature gauge that the temperature rise is slower than normal to operating temperature. it takes a significant time until the level on the gauge is reached for normal operating temperature. my mechanic told me the noise goes away when the serpentine belt is off. he also said it could be my crankshaft pulley. what do you think I should do next?

Hi, have you check if the water pump may be the problem by turning the water pump manually with the belt removed see if you hear or feel any grinding on the pump
what about the slow temperature rise
and can the knocking noise/clicking be from the water pump
what about the slow temperature rise and can the knockin/clicking noise from the water pump more detailed answer
the temperature on the engine is control by the thermostat and the radiator cap are you sure there was a thermostat install? is posible they did not put a thermostat on it and left it with out one.
no they told me they replaced the thermostat
the only way the temperature will slowlly rice is if the termostat was missing or if the electric fan stays on all the time.
it does reach normal opderatng temperature and stays there does not go any higher
correct but the time it takes to get there is control by the thermostat, wans the water reaches temperature it will stay there with a thermostat or with out.
ok
you either have a defective thermostat that stays open all the time or there is no thermostat in it.
is there any possible way the noise can be comming from my crankshaft pulley
you need to remove the thermostat housing and see if is open or precent.
cranck will make noise under load only.
this can be the water pump have you try turning the pulley by hand?
if it was the cranck pulley there would be a vibration as you accelerate do you experiance any?
no i hve not i am bringing it to the dealership ford i just wanted to know what to say
this noise sounds like you have bad pump bearings or the pump shaft bent and heating the walls in the pump housing
ok thanks that is probably what i wanted to hear i am going to ask them to focus on the water pump
i am confident that the slow rice on temperature is the thermostat defective or missing and the noise is coming from the water pump itself.
and i am also have them check my thermostat
ok thanks i accept
thank you .
thank you.
