Leaking from water pump and timing belt is slasded

Depends upon the source of the water leak. Common places to leak are at hose connections, the radiator core, the heater core, or the water pump. Once you have identified the source of the leak, repair or replace parts as needed. If you have a 6-clyinder model, the water pump is located behind the timing cover, driven by the timing belt. Many owners believe that the repair shop is trying to rip them off when thy recommend water pump replacement at timing belt replacement time and opt not to do it since the pump is working. Unfortunately, the new timing belt will cause a different wear pattern on the pump shaft and almost unfailingly, the pump will leak within a few weeks or months after the timing belt is done. Many shop now refuse to replace the timing belt without water pump replacement for this reason, or will make the owner sign a waiver of responsibility if they refuse the additional service/cost.

If the water pump is leaking, it needs replacement. Timing belt is replaced at certain mileage intervals . You can have the belt inspected by a garage. The timing belt does not have to be changed to replace the water pump. If a timing belt is changed, then it is standard procedure to change the water pump, since the water pump is removed when replacing the timing belt.

All three of these engines a timing belt driven which means the water pump is also timing belt driven. The water pump is located behind the timing belt covers on the front of all three engines. The timing belt has to be removed in order to service the water pump. Yes coolant can leak out the pump when it is bad.

whether it is driven by the belt depends on which motor you have in it, but it seems to me that yours probably is. standard practice is to replace the pump at the same time you replace the timing belt if it is indeed driven by the timing belt, and no, you will not harm your valves if your water pump is leaking, but if the water pump bearing fails and the belt shifts position then you will almost definitely bend your valves.

Your water pump is leaking,here's a guide to the timing belt cover.Here's a repair guide on your water pump.

no that is the drive belt

This does sound like your water pump is leaking, or your head gasket has busted on the outside edge. I would check the water pump first, as it is fairly common for the seal to bust and leak coolant from the water pump.

Well, if that Radiator hose is not leaking, then the Water pump seals have gone bad. More than likely you need a new water pump.

Vehicles w/ Timing Belt Driven Water Pumps Should Always Have The Water Pump Replaced When The Timing Belt Is Replaced.

If you do not, then the Timing Belt will fail, turning a low cost repair into thousands because of valve train damages. . .

For the Timing Belt & Water Pump KIT - its around $258 through NAPA

That's the water pump leaking, also change the timing belt, due to the water pump is timing belt driven, this is an interference engine, if the belt goes bad because of the water pump, you will have piston to valve damage. hope this was very helpful.

5. Install the drive belt, water pump pulley and then adjust the auto tensioner.
6. To adjust the drive belt tension, hang the belt on the pulley of the tensioner and install the tensioner.
   NOTE If the tensioner is already installed, loosen its mounting bolts to allow belt installation
   
7. Install the drive belt.
8. Adjust the belt tension to specification by turning the adjusting bolt clockwise or counterclockwise.
9. Air conditioning belt tension should be 0.28-0.039 inch. Alternator belt tension should be 0.39-0.051 inch. Power steering belt tension should be 0.31-0.051 inch.
10. Torque the tensioner assembly bolt to 33-36 ft. lbs. (45-50 Nm).
11. Refill the coolant.
12. Run the engine and check for leaks.
