If after you have done the suggested gasket replacement you still have a problem try K and W block sealer. It may slightly plug up your radiator but it does wonders for small cracks.
For the first few days after gasket replacement fill with water only. This will prevent antifreeze from getting into your motor if there is still a slight problem. You really should have it magnafluxed to be on the safe side.

Sounds like either a blown head gasket, a cracked head, or a cracked block. The solution would be to determine where the coolant is getting into the oil and address that problem.

Ok could be a blown head gasket or cracked head/block. but the 99.9%
cause is the lower intake gaskets have failed. all of that era 6 and 8 clyinder engines had this happen at least once in their life time. they leak externally and internally into the cam galley, mixing the fluids and damaging the engine. fel-pro has a revised gasket set called the perma-pro the o-rings are white instead of orange in the gaskets, these are plastic and rubber low-tourqe seals instead of the older style.

I just ran into his i changed the intake manifold gasket , these models are know to do this ,if your having overheating issuses then more than likely it may be the head gasket but like the ohter problem solver said 99.9% of the time its the intake gaset, make sure you run a motor flush thru it aswell and change the oil you should be good to go

    Place the block of wood on the floor jack. Slide the jack under the engine and raise the engine slightly. Unbolt and remove the front engine mount. On the 4A-GE engine, loosen the power steering and air conditioning belts by loosening the adjusting nuts or bolts on the slider bracket and sliding the accessory toward the engine. Remove the belts.

  • 3Loosen the water pump pulley bolts with the appropriate socket. Loosen the alternator locking bolt and the pivot nut. Push the alternator toward the engine to loosen the tension on the belt. Lift the belt off the pulleys.

    Remove the four bolts on the water pump pulley using the appropriate socket. Remove the water pump pulley. Disconnect the water inlet and bypass hoses from the inlet pipe using a screwdriver or pliers, depending on the type of clamp used.

  • 5

    Disconnect the water inlet pipe by removing the two clamp bolts and the two nuts behind the pump. Remove the inlet pipe. Remove the O-ring from the back of the pump. Remove the mounting bolt on the oil dipstick tube. Remove the tube and the dipstick. Plug the hole with a rag so that debris doesn't get into the crankcase and contaminate the oil.

    Engine runs smooth and the head gasket has been replaced,I already know I need a new radiator..There is a small amount of white smoke at start up,and my oil is milky looking>


    milky sump oil is coolant in the sump
    could be head gasket
    could be the aluminium housing behind the water pump has corroded and leaking water into the sump
    that will account for you thinking that you need anew radiator

    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.

    1993 toyota corolla how to replace watwr pump


    1. Place the water pump gasket (O-ring) on the block and install the pump. Tighten the mounting bolts evenly to 11 ft. lbs. (15 Nm). Install the timing belt covers, making sure they are properly seated and not rubbing on the belt or other moving parts. Install a new seal (O-ring) on the dipstick tube and lightly coat it with engine oil. Remove the plug and install the dipstick tube and dipstick; secure the mounting bolt to 82 inch lbs. (9 Nm).
    Using a new O-ring, install the inlet pipe to the water pump.
    Attach the clamps and bolts to hold the pipe in place and tighten to 7-9 ft. lbs. (9-12 Nm).
    Connect the water inlet and water bypass hoses to the inlet pipe.
    Install the water pump pulley and temporarily tighten the four pulley bolts.
    Install the drive belts on all the pulleys and adjust all of them to the correct tension.
    With the belts in place and adjusted, the water pump pulley will now resist turning. Tighten the pulley bolts to 16-18 ft. lbs. (22-24 Nm).
    Install the front engine mount (mounting insulator).
    Confirm that the draincocks are closed on the engine block and radiator. Refill the engine with coolant. Reconnect the negative battery cable. Start the engine and check for leaks.

    1. Disconnect the negative battery cable.
    2. Drain the cooling system.

      CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

    3. Remove the air cleaner assembly.
    4. Loosen but do not remove the four coolant pump pulley bolts.
    5. Raise and support the vehicle safely.

    2001 Dodge Intrepid overheating - blown engine?


    The timing belt drives the water pump so it would be advisable to replace the timing belt if you replace the pump and visa versa. The timing belt should have been replaced at 105,000 miles and if you did replace it at that time, then I would not replace it again unless it is soaked in leaking coolant. If not, then for sure replace it. Replace the tensioner if it is defective. You need to find a good mechanic that is not just guessing as to what is wrong. If you have no apparent external leak and you are seeing a milky substance on the underside of the oil cap, you may have a blown head gasket. Do you see white smoke coming from the exhaust? Do you see air bubbles escaping from the radiator with the cap off and the engine running? If so you have a blown head gasket or cracked head. A compression test will help determine this one way or the other. A dye test on the cooling system will also help tell you where the coolant is leaking. If the water pump is bad it should be leaking. 130,000 miles is not that much on a modern engine. This engine will easily last 200,000 miles if maintained properly. So it is worth repairing, but that is your decision. You just need to find a good mechanic that actually knows what they are doing.

    Make sure it's cool, pop the radiator cap, Remove the shield on the passenger side between the tire and front of engine. Relieve the tension on the serp belt,draw yourself a diagram of the pulleys and belt routing in case the sticker is gone on the strut tower, remove the serp belt. Take the bolts out of the pulley on the front of the water pump (3). Remove the lower radiator hose at the front cover to drain the coolant. Remove the 6 mm bolts holding the water pump to the front cover housing. tap on the pump with a rubber hammer. Install a new gasket on the new pump, and a weap hole diverter in the pump (round black about hte size of a quarter), use old one if there's no new one. Install pupm and tighten bolts snug with a 1/4" ratchet. Install pulley and 3 bolts. Install belt, top off radiator with 50/50 mix green coolant. start engine and run to operating temperature,make sure the belt is seated in all of the pulleys and is running true, radiator fans should come on. Shut engine down and let cool overnight. Check level in radiator and overflow bottle, top off as necessary.

    No. You don't have to remove the timing belt to change the water pump. Check out the autozone.com website and register. It doesn't cost anything and you will have access to a repair manual for the vehicle. The steps for replacing the water pump can be found there. ( I checked) Hope this helps and best wishes.
