The rear plugs can be painful to get to.  The right way to do it is to remove the intake manifold and number of brackets/nuts bolts, etc. to make enough room to get to the plugs.   There is a reason why they use the long life plugs.   Note that this is not unique to the Highlander, a number of other manufactures with V6 or V8 engines also have hard to reach rear plugs - some require removing the engine to get to the plugs!
The Estima is the JDM version of the Previa - same vehicle, different markets.
Hello again peeps in Toyoland!

I\'m starting another instalment in what promises to be an epic series of DIY articles on replacing various parts for numerous Toyota models. This thread will demonstrate the procedure for replacing the EGR valve on a \'99 Camry V-6. This guideline should apply to all Camry V-6 models in this generation\'s model range. Let\'s dig in!

EGR Valve-   **620-20020    $178.83 (at OEM parts sites like - $246.70 (at dealerships)

1. Disconnect the negative battery cable.

2. Remove the air cleaner hose and lid. Disconnect the IAT sensor wiring.

3. Disconnect the accelerator cable bracket from the throttle body.

4. Remove the throttle body from the air intake chamber.

5. Unbolt and remove the engine hanger, air intake chamber stay and EGR vacuum modulator. Discard the vacuum modulator gasket.

6. Loosen the union nut of the EGR valve. Disconnect and label the hoses attached to the valve.
Disconnect the EGR gas temperature sensor wiring.

**Prior to EGR valve removal, label all hoses for the EGR valve (1) and vacuum modulator (2)**

7. Remove the nuts, EGR valve and pipe. Discard the gaskets.

**Remove these three nuts to separate the EGR and modulator from the intake manifold**

--To install--
1. Place a new gasket on the cylinder head facing the protrusion downward. Install another gasket on the EGR valve and pipe and secure with the mounting nuts. Tighten them to 9 ft. lbs. (13 Nm).

2.Connect the EGR gas temperature sensor wiring.

3. Attach the vacuum hoses to the valve in their proper locations.

4. Tighten the union nut on the EGR valve to 43 ft. lbs. (59 Nm).

5. Install the air intake chamber stay, vacuum modulator and engine hanger. Place a new gasket into position facing the protrusion downward.

6. Tighten the assembly down with the bolt and attach the hoses.

7. Install the throttle body with a new gasket. Attach all wiring and hoses removed.

8. Connect the accelerator cable bracket to the throttle body.

9. Install the air cleaner and hose. Attach the IAT sensor connection.

10. Attach the negative battery cable.

Toyota! (and Lexus and Scion) / How-To: Replace the Water Pump on a \'03 Matrix
« Last post by SirToyoda on August 09, 2011, 03:30:11 PM »
Hello again Toyota fans!

Over the weekend a customer dropped off their \'03 Matrix equipped with the 1ZZ-FE engine and wished to replace the water pump on the vehicle. If your Matrix has over 90,000 miles then chances are that the water pump is getting old and tired, so follow this elementary write-up to swap out that worn water pump by yourself!

**Helpful Reference Material**
2003 Matrix Water Pump diagram- Access the diagram by clicking on the \'Get Info\' button under the \'Parts Listing\' tab, a window pops up and you press the \'Go\' button. The diagram is thereby displayed.

1) Drain the cooling system.

2) Remove or disconnect the following:

Negative battery cable
Right-hand engine under cover
Drive belt
Water pump

2) Install or connect the following:

Water pump. Torque bolts marked A (short) to 80 inch lbs. (9 Nm) and bolts marked B (long) to 96 inch lbs. (11 Nm).

Drive belt
Right engine under cover
Negative battery cable

3) Fill the cooling system to the proper level.

4) Start the vehicle, check for leaks and repair if necessary.

5) You should be all done. Keep in mind that I wrote this in haste so I didn\'t elaborate on each individual step as much as I usually do. I will supplement the guide with further information should anyone request it :)

Hello ToyoLand peeps!

I\'m a recreational Toyota mechanic and full-on Toyota aficionado here that would like to share a write-up on replacing an oil pan on a \'98 Corolla. This is a moderately intensive mechanical job so if you\'re a beginner when it comes to turning a wrench then I recommend enlisting the help of a more intermediate mechanic :)

1) Drain the engine oil.

2) Remove or disconnect the following:

Negative battery cable. On vehicles equipped with an air bag, wait at least 90 seconds before proceeding.
Under covers
Front exhaust pipe
Oil pan mounting bolts and nuts
Oil pan, cutting off the applied sealer.

To install:

1) Remove any old sealant from the oil pan flange and thoroughly clean the sealing surface.

2) Install or connect the following:

Oil pan. Tighten the bolts and nuts in several passes. Bolts and nuts: 80 inch lbs. (9 Nm).
Front exhaust pipe
Negative battery cable
Under covers

3) Fill the engine with clean oil.

4) Start the vehicle, check for leaks and repair if necessary.
Toyota! (and Lexus and Scion) / Highlander 2004 Changing Plugs

Hi All,

I\'ve searched and searched for the answer to this and can\'t find it anywhere, not even in the official service manual.  How does one change the back six plugs on the Highlander?  Any suggestions will be appreciated or links to where it is explained.

I went to the Toyota website and found that they do not have Toyota Estima model listed. However, I noticed that the Toyota Previa are of the same design as Toyota Estima. Are they the same?

Thanks for posting your resolution to your topic.  Pretty bizarre way to get stuck, but anything is possible with clearances the way they are.  Nice \"MacGyver\" fix on the throttle shaft to take up the slop - quite ingenious!
