I would start with the thermostat first especially if your not leaking coolant or hearing strange noises. Would also need to know what engine you have. Some Toyota egines require that you remove the timing belt to access the water pump if this is the case your better off replacing the timing belt, crank case seal and tentioner pulleys if your there anyway. tech note there is a timing belt kit which contains most of these item. But I would definitely start with the thermostat. In most cases it can be located by following the largest upper hose connected to your radiator down to the engine. It usually lies right there within.
Answering "How do you replace the water pump on a 1994 Toyota Camry?"
It's recommended to change the water pump at the time when you replace the timing belt.
It's recommended to do when you are replacing the timing belt.
The same way you change the timing belt. the water pomp runs off the timing belt. It,s a pain in the butt.
draing radiator water from toyota camry1994
how do you install a water pump on a 1992 toyota camry
You can find it in the water outlet.
It is located on the bottom of the radiator
No Camry has ever had a v4 engine. There is a v6 and an inline 4 cylinder. The timing cover typically needs to be removed making it an ideal time to also replace the timing belt. this is a fairly complicated job and is often best left to a qualified technician.
You do not need to, but it's highly recommended. If water pump fails after you change the belt, you will have to do the same work as before to replace the pump.
I would gees $ 60- $150
They are in the water because the sealions chased them away.
