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.

Wat all do i need 2 move 2 remove the brake booster from a 2001 montana


You will need to remove the fluid lines going to the booster, the vacuum line coming from the plenum also any electrical cables for the fluid level sensor etc. Then you remove the bolts securing the booster to the large round metal box its attached to. You can then either replace the booster or run a rebuild kit through the unit. A rebuild kit should be purchasable through your local parts shop.

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.

What do you think the chances are that a maf sensor is causing codes p0171 and p0174,causing the check engine light to come on?


Clean the MAF Sensor---CRC MAF Cleaner
The maf sensor is fairly reliable and fairly expensive.
They just repair them,so I would say no

Vacuum leaks are the most likely,causing both banks, to drive the O2 Lean

Egr Valve worth checking out

Loose O2 Sensors

Exhaust letting air in

Ducting to throttle or air filter cover loose

Etc

Wont idle, runs good ,when you let off the gas it dies


The symptoms you're reporting indicate you have a vacuum leak. Look for;
1) damaged, loose or missing vacuum lines.
2) loose throttle body.
3) unplugged opening in the intake manifold or
throttle body.
4) loose bolts or missing bolts on the intake
manifold.
5) If you have hard shifting as well check for a loose
or missing vacuum line on the transmission.
You can use canned ether to check suspected leaks, the engine will either rev or sputter if there is a leak. Don't just spray the ether randomly that is very dangerous. HAVE A FIRE EXTHINGUISHER HANDY, ETHER IS VERY FLAMABLE! CO2 exthiguisher is best, dry chemical make a nasty and hard to clean up mess that is caustic.

2000 Sportage: where is the spark plugs located on a 2000 Kia Sp...


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.
