Why not tell what engine is there. in the 2000 car, and country.
diff, counties use diffr. engines...(called options, etc)
we had this choice, in 2000
3.0 L 1MZ-FE V6 (1998-2000)
3.0 L 1MZ-FE V6 (01-03, VVT-i) 210 hp, 220 lb·ft

so 1mz.
spark out , the service manual covers that, buy one?
or use alldata.com>?

to get the manifold off with all bolts off , takes hitting it with a
rubber mallet, to break the bond, (all cars made) if not lucky,.
toss a coin.
now that 1mz is known any one can google that. and the first hit lands.

knowing the name 1MZ , makes all this easy . no?

see what others do to cheat the book, (oldest story on earth this)

i think the issue is cab forward design of body, making sparks
a PITA to remove..
but is not, if you use the right tools. and techniques.

SOURCE: I need to remove the upper intake manifold plenum.

There are no fasteners inside the plenum, The electrical connection for the injectors is very tight due to a rubber ring gasket the seals the injector assembly to the plenum. Carefully push down on the electrical assmbly while prying up the plenum. You also may have to remove the thermostat and hose. I've done this 3 times on my ladies 96 Yukon.

How to remove air from cooling system 1999 nissan maxima


Remove the negative battery cable from your Nissan Maxima. Wait at least 10 minutes in order to prevent the engine cooling fan from causing any potential harm while your hands are near it. Additionally, the engine must be completely cool in order to safely remove the air intake manifold.

Use a screwdriver to remove the hose clamps around the air intake duct. Gently pull the duct from the rest of the manifold.

Disconnect the accelerator cable, cruise control cable, hoses and electrical connections from the throttle body. Coolant may be lost through some of the hoses, which can be prevented by utilizing hose clamps or plugs. Be prepared with a catch pan underneath the hoses to collect any major spills.

Disconnect the spark plug wires from both the spark plugs and the retainers on the plenum. Unbolt the distributor cap. Use a pen and tape to label each wire with its location so that you can easily return each wire to its exact location once the air intake manifold has been put back in place.

Disconnect the ground strap, which is attached to the upper plenum of the air intake manifold and use a socket wrench to loosen the bolts. There are 11 bolts on the upper intake plenum.

Remove the upper plenum, which should still be attached to the throttle body. While the upper plenum of the Maxima's intake manifold is removed, it is a good idea to clean the mounting surfaces as well as the inside of the manifold with a stiff wire and brake cleaner. Use lint-free mechanics' rags to wipe away carbon buildup.
Removing the Lower Plenum

Drain the cooling system by inserting a catch pan beneath the radiator's drain bolt. Unscrew the drain bolt and hold up a 3/8 hose with a funnel on the end of it to direct the coolant to the catch pan. Open the drain fitting with a pair of pliers and remove the radiator cap.

Remove the radiator hose from the thermostat housing and disconnect the electrical connections from the coolant temperature switch and the coolant temperature sensor. Label these connections with tape and pen as described above for the upper plenum hoses and wires.

Remove the bolts to disconnect the coolant pipes at the transmission's end of the intake manifold.

Loosen the bolts on the lower manifold by turning them in 1/4-turn increments until they can be removed by hand. The manifold may need some gentle nudging to be released from the cylinder heads, but do not pry it loose -- doing so can cause damage to the sealing surfaces, leading to vacuum leaks.

Use a scraper to remove any gasket material and sealant from the outer parts of the manifold and cylinder heads. Clean the mating surfaces with lacquer thinner or acetone so that a new gasket can be applied to the lower manifold.

97 dodge stratus 2.5 car turns over but does not have spark. There is fuel. I replaced the ECM crankshaft position sensor.


I would start with the rotor and cap. I just worked on one and it was the distributor was bad.

If you need to remove it and rplace it heres how.

Distributor Removal and Installation REMOVAL
  1. Remove bolt holding air inlet resonator to intake manifold.
  2. Loosen clamps holding air cleaner cover to air cleaner housing.
  3. Remove PCV make-up air hose from air inlet tube.
  4. Loosen hose clamp at throttle body.
  5. Remove air inlet tube, resonator and air cleaner cover.
  6. Remove EGR tube.
  7. Remove spark plug cables from distributor cap.
  8. Loosen distributor cap hold-down screws and remove cap.
  9. Mark rotor position for installation reference, then remove rotor.
  10. Remove two harness connectors from distributor.
  11. Remove two sets of distributor hold-down nuts and washers from studs.
  12. Remove bolt and spark plug cable mounting bracket from top of distributor housing.
  13. Remove bolt and transaxle dipstick tube.
  14. Carefully remove distributor from engine.
INSTALLATION
  1. Install rotor on shaft.
  2. Position distributor in engine and ensure O-ring is properly seated on distributor. Replace O-ring if it is cracked or nicked.
  3. Carefully engage distributor drive with slotted end of camshaft. When the distributor is installed properly, the rotor will be in line with previously marked line on air intake plenum.
  4. If engine was cranked while distributor was removed, establish proper relationship between distributor shaft and No. 1 piston position as follows:
    1. Rotate crankshaft until number one piston is at top of compression stroke.
    2. Rotate rotor to No. 1 rotor terminal.
    3. Lower distributor into opening, engaging distributor drive with drive on camshaft. With distributor fully seated on engine, rotor should be under No. 1 terminal.

You will have to remove the intake manifold (this is the solid large plastic cover that covers the top of the engine when you remove the engine cover). There are many wires and small vacuum hoses to disconnect. Plus.., when re-installing, it is a common problem the manifold cracks if excessive torque is applied to the fastening bolts. And you probably should relpace the intake manifold gasket.You can then remove the thermostat assembly by disconnecting the hoses and loosening the mounting screw.

----------

The procedure as per service manual is as follows:----

Following the Service Manual instructions, drain the coolant circuit, then remove the return pipe and the short rubber hose connected to the engine main coolant rail (1 clip at the bottom + 1 clip at the top). You remove also the outlet hose (1 clip at the engine outlet spout + 1 clip at the bottom pipe, you need to loosen the pipe mount to remove the hose). Once removed the return pipe you can undo the coolant rail: 2 (tight) bolts below the rail and the oil dipstick bolt holding the thermostat housing. Doing this without the manifold in place is simple, but its not that easy with the manifold on.... once loosened the coolant rail you can remove the thermostat housing. You open it (3 bolts) and replace the old thermostat with new. All 3 gaskets should be replaced, to minimize the risk of leaks. Apply silicone lubricant on the O-rings, then fit housing + coolant rail back in.

This will help you.Thanks.Helpmech.

They are under the black plastic cover that is in the middle of your valve cover gasket. Remove the intake hose from the aluminum intake plenum on top of the valve cover and the silencer box against the firewall. Remove all the connectors from the sensors which should be 2 on the plenum and the 2 large vacuum hoses on the plenum. Then remove the 3 12mm bolts from the plenum at the throttle body and remove the plenum. You can reuse the throttle body gasket at the plenum so don't destroy it. All the other bolts are 10mm and use a screwdriver to loosen the clamps on the hose. The sensors have clips that you need to remove with a small screwdriver, then disconnect them. Remove the bolts on the cover and the cover. Then remove the bolts holding the coil packs down. Do one plug at a time. 2 of them are connected to the 2 plug wires and 2 are underneath the 2 coil packs. The connectors on the coil packs are fragile so remove them carefully. Reverse the steps to reinstall the plenum, etc.

Gettting the intake plenum off a 02 freelander


My 2002 Land Rover Freelander V6 thermostat crapped out as well and I decided to replace it myself.

The plenum is deceptive, but after 3 hours of looking and trying I finally got it off. Of course there are many hoses and electrical connections that need to be removed, but that's the easy part because you can see them all. The bolts that hold on the plenum are what your worried about and I will now tell you where they are. Read this and you should take about 30min to remove the plenum.

There are a total of 6 bolts to be removed that secure the intake plenum to the intake manifolds.

First remove the 4, 10mm large and obvious bolts at the top of the plenum. Now here is the tricky part, there are 2 bolts that are at the back of the plenum near the fire wall. As you are looking at the intake plenum from the front of the car, they are on the back side of the plenum near the fire wall on the passenger and driver side of the intake plenum.

Both bolts your looking for are 8mm bolts. If you remove a 10mm bolt, your removing the bolts that secure the rear spark plug coils.

The driver side rear intake plenum 8mm bolt is secured to the plenum itself. Fell with your hand about the back of the plenum on the right side for a lone bolt that is in the plenum with a metal tab that goes down to the back of the rear cylinder head. Remove the bolt that is attached to the intake plenum, not on the rear cylinder head

The passenger side one is a bit different. Feel on the back of the intake plenum about the passenger side for a metal support tab that comes down from the intake plenum and secures to the rear cylinder head. Where the support tab attaches to the head is a 8mm bolt that you remove.

Now here come the leap of faith. If you have the 4, 10mm obvious bolts removed and the 2, 8mm from the rear of the plenum removed, and if you can rock the plenum up and down about 2-3 inches,but it still feels like its attached to the intake manifolds in the middle of the engine, then you have removed all the bolts that secure the intake plenum to the engine. This is good.

The intake plenum is now being held on by the rear intake manifold by 3 O-ring gaskets. Push onto the back of the intake plenum near the firewall to expose a gap at the front of the intake plenum at the front intake manifold. Put 2-3 long flat screwdrivers into the gap or a small pry bar, and ever so gently but forcefully, apply prying force as to not damage the mating surface of the aluminum intake manifold, until the intake plenum pops off. It will just POP off.

Now that the intake plenum is popped off, take careful note of all the electrical plugs and hoses as to where they attach. You will not need any tools to disconnect the electrical plugs or hoses. To remove the hoses, push down the red ring with you fingers that the hose goes into and pull on the hose, it should come out very easily. The electrical connectors, push on the metal clip down and pull the connector loose. The electrical connectors only plug into their own plug, so you cant mess them up.

Tools you will need to replace the thermostat;

1. 8mm combo wrench. Make sure its not too long, shorter is better.
2. 10mm socket, shallow. 10mm combo wrench
3. 2-3 flat screwdrivers, for prying off the intake plenum
4. Ratchet wrench
5. 1 foot long worth of socket extensions. 2 6inch extensions will work as well
6. Universal socket joint
7. Angled needle nose pliers make it easier for hose clap removal, but straight needle nose pliers will work
8. Diagonal cutters to cut securing zip ties for the wiring harness

Take you time, once the plenum is off it goes pretty smooth after that. We removed just the forward intake manifold and that was more than enough clearance to remove the thermostat. You do not need to remove the fuel rail or spark plug coils from the manifold but you will need to disconnect the electrical connections to move the intake manifold out of the way.


Take pictures, there's a lot of hoses that go all over the place. The electrical connectors are only long enough to go where their supposed to go.

Then take that UK piece of **** to the dealer and trade it in for anything made in the USA or Japan. Changing a thermostat in any of those will only take 10 min and require 1 tool.

2004 Hyundai Sonata 6 cyl


Depends on how MECHANICALLY INCLINED you are. Have you done any repair work on vehicle engines before? It's not that difficult to do if you know how to turn a wrench/ratchet and THINK about what you are doing and what you are dealing with... .attention to details. Ya think? On the 04 2.7 lit V6 Sonata, there are two nuts and 5 bolts (two long and three short) which hold the plenum to the RISER manifold. There are an additional 3 to 4 bolts at the rear (firewall side) which support the plenum (they're all 12mm bolts). You'll need to remove the intake air hose to lift the plenum out of the way to access the 3 plugs on the RH side (rear) of the engine. You'll want to replace the plenum gasket when you do this. When you reinstall the plenum, the tightening torque is 11-14 lb.ft. Do not tighten the REAR support bolts until after you torque the surge tank bolts to the intake (riser) manifold.
