    Not the radiator drain plug. The drain plug on the engine to drain the coolant that is in the engine....

    I have heard there may be a drain plug underneath the exhaust manifold, on the block, but it is still recommended to drain the coolant using the lower radiator hose. Just disconnect it from the radiator, and all fluid (even in the block) will be drained out.

    Thanks. My Haynes manuel shows a drain plug on the engine block too. Have done this before on this vehicle, but can't remember if I drained from both plugs.

Should be at the bottom of the radiator. If you are unable to find it, just disconnect the bottom radiator hose, from the radiator, and reconnect it once finished draining.

How can I drain Peugeot 407 2.0 diesel coolant?


That is hard to believe, since the bottom hose is the lowest point in the cooling system. There is an engine block drain plug which would let out what coolant is remaining in the engine, but it would be about a liter at most left in the engine. To completely drain the coolant, remove the block drain-there may be a drain plug on both sides of block, so you should check for that.

Replacing a thermostat on 2004 nissan sentra


  • Prepare for the replacement by disconnecting the negative battery cable and draining the engine coolant into a container--you need to remove the drain plug from the radiator first and then the drain plug at the engine block.


  • Remove the engine's cooling fan by loosening the fan/water pump pulley nuts, unclipping and removing the fan shroud's lower half, removing the water pump pulley nuts and pulling the fan out from underneath.

    Disconnect all components blocking access to the thermostat by removing their bolts. On four-cylinder engines, this includes the air cleaner, air intake duct and the power steering pump's support bracket. On a 3.3 liter V6 or SOHC engine, remove the upper radiator hose from the intake manifold's coolant outlet.

  • Slip off the drive belts blocking the thermostat by turning their tensioner bolts with a wrench or breaker bar. On a 3.3 liter truck or DOHC engine, follow this by removing the upper idler pulley bracket. On a 3.5 liter engine, remove the water pump drain plug from the front end of the block.

  • Detach all hoses from the thermostat housing cover by loosening the hose clamps with pliers; this usually includes the lower radiator hose. This is only needed on V6 engines; you will keep the hose attached on a four-cylinder.

  • Remove the thermostat housing cover by removing its bolts. There will be some coolant spilling out when the gasket seal breaks.


  • Disconnect and remove the thermostat from its cover by removing its screws. Take note of how the thermostat is positioned within the cover.

  • Scrape away all traces of gasket or sealant from the housing and cover and clean the surfaces with lacquer thinner.

  • Apply RTV sealant around the edge of the thermostat cover. You need to re-install the cover within five minutes of applying this sealant.

  • Mount the new thermostat into the cover in the same position the old thermostat was in.

  • Re-install the thermostat cover and all other parts in reverse order of installation.

  • Wait a half hour for the RTV sealant to cure before refilling the engine coolant. Use fresh coolant if the old coolant is contaminated.

    Where is the location of the coolent temp. sensor on a 04 dodge truck v6 3.7 . I need to replace it.

    Fig. ECT sensor location-3.7L, 4.7L engines.

    icn_arrow.gifBack to Top Inspect/Test/Replace Because ECT (engine coolant temperature) sensor procedures vary depending upon their location, first locate the part. You may need to partially drain the engine coolant to prevent coolant spillage.

    • Disconnect the negative battery cable.
    • Unplug the ECT.
    • Then, unscrew it.
    • Reverse the removal procedures to install the new part.
    • Connect the negative battery cable to the battery.

    How do i change the water pump on a 2000 dodge,grand caravan


    Removing and changing the water pump on a 2000 Grand Caravan should only be done if your van has a 3.3 liter or 3.8 liter V6 engine. On any other engine types, including four-cylinder engines, you must remove the timing belt from the engine to access the water pump, which is a dangerous task that can mess up the engine if attempted by an amateur.
    The procedure is as follows:------------- The water pump is responsible for sending the engine coolant to the engine.First of all remove the serpentine belt then remove the plastic cove on the passenger side behind the wheel. You will have to remove the pulley. Once the pulley is removed unbolt the water pump and remove it. Clean the surfaces and install new pump. Draining the coolant and replacing it is advisable.
    Drain the engine coolant, twisting and removing the drain plug at the bottom of the radiator
    -------------------Thats it.

    Antifrezz is leaking from the engine no hoses are broke whers is it coming from


    If all your hose and hose clamps are good. There is a good chance that the water pump has to be replaced, once the water pump bearing is worn. The coolant will leak from the weep hole on the water pump when the engine is running and the only way to stop the leak is to replace the water pump.
    Thank you for using fixya.
    Depending on engine size a 3.1 liter v6 and a 2.2 **** 4cyl. are both located in the front of the engine.
    Remove serpentine belt,remove 4 10mm from pulley (v6)(three 13mm for 4cyl.)remove pulley.v6 will have 6 8mm bolts,4cyl. will have 4 13mm bolts-remove clean surfaces install new pump.
    About 40 mins.v6,60mins for 4cyl. Be sure to drain coolant before you start, refill whith proper coolant, some 95 up gm require dexcool anti freeze (orange in color).
