Sadly as vehicles age things like gaskets, seals, hoses and such items become brittle and weak - They are prone to failure and are listed as "check or replace " in the manufacturers service tables at mileage and-or time. The leak may be any item associated with the cooling system, a pressure test should find it. I recomend you have the cooling systems hoses replaced to prevent problems when the leak is repaired.

Remove water pump
Inspect/Test/Replace
  • When replacing a water pump, it is necessary to drain the cooling system.
  • Any components--belts, fan, fan shroud, shaft spacers, or viscous drive clutch--should be removed to make the pump accessible. Some pumps are attached to the cylinder block as shown below.
f11-60.jpg Installing a water pump. Courtesy of Dana Corporation.
  • Loosen and remove the bolts in a crisscross pattern from the center outward.
  • Insert a rag into the block opening and scrape off any remains of the old gasket.
WARNING When working on the coolant system (for example, replacing the water pump or thermostat), a certain amount of coolant will spill on the floor. The antifreeze in the coolant causes it to be very slippery. Always immediately wipe up any coolant that spills to reduce or eliminate the chance of injury.
  • When replacing a water pump, always follow the procedures recommended by the manufacturer.
  • Most often a coating of good waterproof sealer should be applied to a new gasket before it is placed into position on the water pump.
  • Coat the other side of the gasket with sealer, and position the pump against the engine block until it is properly seated.
  • Install the mounting bolts and tighten them evenly in a staggered sequence to the torque specifications with a torque wrench. Careless tightening could cause the pump housing to crack. Check the pump to make sure it rotates freely.
  • The water pumps on many late-model OHC engines are driven by the engine's timing belt. When replacing the water pump on these engines, always replace the timing Test/Replace

    CAUTION
    If the radiator is filled to the top with coolant and the engine is run without the radiator cap in place, the coolant will expand and spill over as the engine warms up.

    • Drain some coolant into a clean container until the coolant level is below the thermostat housing.
    • Remove the upper radiator hose connection from the thermostat housing.
    • Loosen the housing bolts and remove the housing.
    • Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If the gasket remains on either of the surfaces, there will probably bea coolant leak after reassembly. Some engines use a rubber O-ring to seal a thermostat housing.
    • Compare the size of the thermostat to the old one. They are of different sizes, types, and temperature ratings.
    • The temperature rating is stamped on the sensing bulb on the bottom of the thermostat. The temperature bulb faces the block.
    • When replacing a thermostat, be sure that the thermostat fits into the groove in the block or outlet housing. If the thermostat is installed upside down, the engine will overheat.
    • Install the gasket.
    • Reinstall the thermostat housing. Refill the system and run the engine or pressure test to check for leaks.
    • When the engine has reached operating temperature make sure the thermostat opens.
    • You should be able to see coolant circulating within the radiator.
    • Another way of checking thermostat operation is to feel the top of the radiator hose or use a thermometer or multimeter with a temperature probe to confirm that the coolant is warming up.
    • If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced.
    NOTE When a paper gasket is used and the recess is in the thermostat housing, it is a good practice to position the thermostat into the recess and glue the gasket to hold it in place. If it falls out of its groove during installation, the outlet housing can be cracked or a coolant leak will result. Before tightening the water outlet housing, try to rock it back and forth to be sure it is flush. Housings are often cracked during this step. belt.
  • Make sure all pulleys and gears are aligned according to specifications when installing the belt.

How to change my engine coolant in a 1992 ford ranger-v6 3.0 engine, with what kind of coolant and how much of it
Hello again Vicki, you can read my first post to you on type. Now for where and how. Put suitable container under radiator drain valve. Start to drain old antifreeze, you can also loosen radiator cap for faster drain, but make sure antifreeze doesn't start to spill all over your driveway or garage floor. When radiator and engine are mostly drained, I would recommend to change the thermostat. Follow the top radiator hose down to the engine. This is where you'll find the thermostat. Remove the attaching bolts and remove thermostat.If you wish to flush your engine,you can put water down the thermostat hole as well as the radiator cap hole, or you can do a fancy flush. Shut drain below, reinstall thermostat housing without thermostat, fill radiator with fancy flush cleaning solution and water replace radiator cap ,run for time stated on can of flush. Now you go back to where I began and start the draining again. Dispose off antifreeze correctly it is dangerous to animals if they ingest. Close drain,and fill engine with antifreeze thru thermostat housing, when almost to top install new thermostat and gasket. fill radiator almost to top, start engine, open inside heater and let engine warm to operating temperature. At this time the antifreeze level will drop, because thermostat will open, and you can fill some more .This should eliminate any possible air bubbles. Fill your coolant tank. I would like to know how you make out. GOOD LUCK.

I have a 2000 pontiac montana and its making a load noise by the belts and its leaking some kind of oil and the water temp is maxed out
its probably the water pump pretty simple to change locate the large smooth pulley on top of the serp belt take out the 4 bolts take off the serp belt remove the smooth pulley the water pump is under the smooth pulley take out the 5 bolts on the water pump and the water pump will come out on the new water pump the gasket will only go on one way make sure you turn it the right way so the holes line up use a little gasket sealer to hold in the right place replace with new pump on the tension pulley there is a 3/8 square hole that you can put a long handled socket or breaker bar in to loosen the tension on the on serp belt so you can streatch the belt back over the pulleys i only wish the thermostat was as easy to change.

How do you replace a thermostat on a 2002 toyota celica
Toyota Celica, Corolla, ECHO & MR2 1999-05Toyota Celica, Corolla, ECHO & MR2 1999-05

The thermostat is located in the water inlet housing that is connected to the lower radiator hose.
The thermostat is equipped with a by-pass valve. If the engine tends to overheat, removal of the thermostat would cause a decrease in cooling system efficiency.

CAUTION NEVER drain coolant directly onto the ground! NEVER open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

Squealing noise coming from the belts while engine is running
take off your serp-belt and spin your water pump, alternator, idler pully and see what squeaks or feels rough. your water pump bearings may be bad. the only thing you can do is change it. dont forget to change your thermostat and antifreeze. FYI your antifreeze is made with lubricants in it for your water pump bearings.
