Locate engine block antifreeze drain plug

Do I need to drain the antifreeze from the block on my 1998 Windstar before I remove the lower intake manifold to replace the gasket? Or is draining the radiator sufficient?

There is a 3/8" square head plug above the starter. This drains the left bank of the block and can be replaced with a 1/4" pipe valve.

My 98 ford windstar is displaying trouble codes p1537/p1538, along with a misfire on cylinder 1 & 2 (p0301/p0302). what are some problems that can cause this problem?

Codes p1537 and p 1538 are codes for a faulty IMRC valve. They are located on the lower intake manifold.

Intake Manifold Runner Control (IMRC), Vacuum Control
  1. Remove E-clip retaining vacuum control linkage to lever/shaft assembly.
  1. Remove adjustment screw from the vacuum control (9S514) and bracket.
  1. Remove two bolts retaining vacuum control and bracket to IMRC housing assembly.
  1. Disconnect linkage from the lever/shaft assembly and remove vacuum control .
  1. To install vacuum control and bracket assembly, reverse Removal procedure. Tighten retaining bolts to 8-11 Nm (71-97 lb-in). Adjust vacuum control as described.

    Intake Manifold Runner Control (IMRC)


As for the misfire codes, Check out the upper and lower intake gaskets. Since you have to take the upper intake off for the imrc valves its just a few more bolts to remove the lower intake. The intake gaskets are rubber seals. When the engine is cold the seals shrink and causes a misfire. when the engine warms up the seals expand and the misfire goes away.

Where is the thermostat located in the 06 stratus

  • Find the location where the upper radiator hose connects to the intake manifold of the engine by tracing it from the radiator to thermostat intake housing bolted to the intake.
  • 2 Remove the radiator hose from the thermostat intake housing by loosening the band clamp that secures it into place. With the clamp loosened, pull the hose off the housing.
  • 3 Remove the two bolts that secure the housing to the intake manifold and then lift the housing off the intake.
  • 4 Lift the thermostat out of the intake manifold and place the new thermostat into the hole. The end of the thermostat with the pin protruding from it sticks out of the intake manifold.
  • 5 Lift the thermostat intake housing gasket off the intake manifold and place the new one onto the intake manifold.
  • 6 Place the thermostat intake housing onto the intake manifold and bolt it into place. Reconnect the hose using the band clamp.
  • Six-Cylinder Engines
  • 1 Drive the Dodge onto a set of front-end ramps and secure the parking break. Allow adequate time for the radiator fluid to cool down. Thirty minutes is usually adequate.
  • 2 Loosen the petcock on the lower right hand side of the radiator and drain all of the radiator fluid into a drain pan. Close the petcock once drained.
  • 3 Trace the lower radiator hose to the location where the hose connects to the engine block. The metal housing the hose connects to is the lower thermostat outlet. Remove the hose from the outlet by loosening the band clamp and then by pulling the hose off the outlet. Be careful--some fluid will drain from the hose.
  • 4 Remove the two bolts that secure the thermostat outlet to the engine block and pull the thermostat outlet off the block.
  • 5 Discard the O-ring inside the bottom edge of the thermostat outlet and place a new one into the outlet.
  • 6 Pull the thermostat out of the engine block and replace it with a new one. The end with the pin protruding from it sticks out of the engine block.
  • 7 Place the thermostat outlet onto the engine block and secure it into place. Reattach the lower radiator hose with the band clamp.
  • 8 Open the radiator filler cap located on top of the radiator and fill the radiator with the fluid previously drained from the system.

  • please dont forget to give good rateing thank you

    I need to drain the antifreeze where is the plug from the engine block

    The textbook method is to remove the drain plug. Most drain plug is make of nylon/plastic and it may fall apart while you turn it.

    The professional method is to loosen the lower radiator clamp and drop to lower radiator hose.

    Drain the coolant onto a large drain pan and recycle the coolant


    I just did a FREE write up on air purge from coolant system and how to detect initial state of blown head gasket at the Fixya tip selection.

    Where is the coolant block drain plug located on

    None on the block, other than freeze plugs...
    The only drain is on the bottom of the radiator (you knew that)...

    I installed a Prestone motor flush kit and it flushes just fine, but does not "empty" the engine cavities. This is better, anyway.

    You have to splice a "Tee" fitting into a convenient heater hose (highest one).

    Hope this helps..

    I need to drain the antifreeze from the (1998 Ford wIndstar 3.8) engine block so I can remove and replace the intake manifold gasket.

    Not 100% sure but if you look up under exhaust manifold area, on block,is usually a common place. Simple hex head plug into block on most. Are you sure just pulling lower rad hose, and thermostat housing off won't get you where you need to be?

    Have a 1999 lexus es300. Getting indications that knock sensors need to be replaced. Car has 144k miles. What do the knock sensors do and how easy / tough to replace?

    If you have some common tools the knock sensors are no big deal.  If you take a lexus they will make is sound like you need to completely disassemble the engine and scare you off.
    First, do you really have a problem with preignition causing real knocking due to carbon buildup, or diluted gasoline or do you have failed knock sensor(s).  Try to decarbon the engine first.
    There is a technique used with water being sprayed into a warm engine intake.  This will clean up the valves and carbon buildup which can result in engine knocking.  

    The job will be a couple hundred for the parts and a couple hours of your time.  After you are done, you have entitled yourself to approximately $500 in new tools for your tool chest since this is what Toyota and Lexus will charge to fix (about $1k+).

    You will need to buy the following to address the knock sensors and a couple other items while you're in the neighborhood.
    - 1x upper intake plenum gaskets - 2x lower intake plenum gasket - coolant bypass hose found in the same area as knock sensors - 2x knock sensors (bank1 and bank2) - short pig tail cable which connects both knock sensors to common wire harness. - toyota antifreeze  (2 gallons, if i remember correctly... when mixed to 50/50 (antifreeze/ water) you will have 4 gallons.
    drain the radiator drain the front of the engine using the engine drain plug - this plug is on the front right side facing the engine, behind the right hand exhaust manifold. (this will lower antifreeze enough to avoid dumping antifreeze all over the engine later) remove the air filter box remove the connections into the throttle body remove the cable from the throttle control remove the upper air intake plenum remove the two lower air intake plenums remove the antifreeze fill port
    Knock sensors will be in the valley between the lower intake plenums.  You will need to remove the rubber antifreeze bypass hose (little short hose blocking access to the knock sensors).
    By the way, the reason you bought a replacement, is that if this short hose splits from normal wear, you need to spend this money and effort to reach it, so just do it now.
    The little pig tail cable which connects both knock sensors to the wire harness is said to cause a big majority of the problem due to the plastic getting hot and brittle, falling off and shorting to the engine.  While in this mode the engine thinks knock is occuring and starts to retune the air fuel mixture to get rid of the knock until it goes into minimal operations mode.
    After replacing the knock sensors (and tighten to torque specs), replacing pig tail cable, and reinstalling your new short by pass hose.  Replace the lower gaskets, antifreeze fill port, lower intakes, upper gasket, upper intake, air intake, air filter, reattach everything, reconnect all the rubber lines you pulled off, make sure there are no splits in the air intake passage anywhere, retighten the engine antifreeze drain plug, and the drain on the bottom of your radiator, and your done!
    Don't forget the easy stuff.  Dilute the antifreeze with water and fill the radiator and overflow tub.  Run the engine for several minutes until its hot and opens the thermistat to allow antifreeze into the empty engine cavities.  Turn the engine off and get a cold one as the engine cools.  Once absolutely sure engine is cold, refill the radiator with antifreeze and refill the reserve tub.  Do this at until all the beer is gone and you are both full of antifreeze (in one form or another)..... obviously red stuff in the car, amber down the gut.
