Corolla Water Pump - How to test leak?

One mechanic told me that my Toyota Corolla 2004 CE's water pump is leaking and I need to change pump and its belt costing me around $450. I took it to other mechanic today and he told that water pump looks good and no need to worry. I need to know how I can verify that water pump is leaking or not. Below are some facts of the car that I noticed myself.1. The engine collant level is above half level about at 70% 2. I started my car around 8.30 PM @ 90 degree F after break of 3 hours and the temprature gauge reach to half in 5 minutes.Please advice what can be done to determine the leak is there or not else I have to take it to other mechanic.

Answer:

Look at the water pump. You will see a pink residue around the shaft. That's dried coolant that has leaked out. Feel underneath the waterpump's shaft housing (with the engine cool). It will be moist where there's a hole underside the housing. The hole is supposed to be there. Replacing that water pump is very easy for a mechnaic. The Corolla CE since 1998 has a timing chain instead of rubber belt. You don't need to remove the chain to get at the water pump. It is on the engine block and you'll need to take off the serpentine belt, passenger side front wheel, and an access panel in the wheel well. The pump costs about $50 and takes about 1/2 hour to change. The other $300 dollars is for the guy you talked to to pay his bookie. The serpentine belt will cost about $30 and takes 5 minutes to change. It has a spring loaded tensioner. The coolant level should never go down if there's no leak.

You did not say how many miles your 2004 Corolla CE currently has? We have owned 5 Toyotas from brand new and 211,000 miles is the most mileage we have gotten was on a 1993 Toyota Camry that did require radiator replacement. However, one of the more expensive preventive maintenance expenses requires replacement of Timing Belt every 75,000 to 90,000 miles when it also makes sense to replace Water Pump, Thermostat and both fan belts etc in one overhaul saving on expensive labor and normally being worry free of any breakdowns. If you are not overheating (meaning Temp Gauge runs normal) then I would say 1st Mechanic was just to put wool over your eyes but still one should always watch observe temperature gauge while vehicle is in operation and never run or drive if HOT <= put over to side of road and if recurring then carry gloves/bottle of water and see a good trustworthy mechanic. Hope the Above Info Helps!

the only way to tell if the water pump is leaking is if it leaves little drips or big puddles if you dont see any drips its probably not leaking just watch the coolant level
