For 4.0 / 4.6 BOSCH Engines Throttle Body Heater Replacement (Kit # MGM000010K) Performed on 2002 Discovery Series IIHi I'm Doug, your tech representative here at Atlantic British. In this video we're going to talk about a common issue with the 4.0 and 4.6 BOSCH engines which is the coolant regulator heater plate that's on the bottom of the throttle body. These leak quite often. As a matter of fact in this case what we're going to do is we're going to show you one on this Disco 2. This is a 2002. Where the heater plate is located on the bottom side of the throttle body just under your throttle plate. And you can see the build up of coolant right on the edge there which is telling me we have a leak. Now we had to add some fluid to this vehicle over a couple weeks. So we knew we had a leak and that's where we found it. So what we're going to do is we're going to remove that throttle body and we're going to install this kit MGM000010K. And what you get is the actual replacement plate. The gasket. And the 3 screws with lock washers that hold them in place. We're also going to need a throttle body gasket. We want to replace that after removing the throttle body. That's an ERR6623. This is basically is all you're going to need to fix this. And it's a relatively easy fix. So first we're going to start with removing the intake tube, the throttle cables, and then the breather hose on the back side of the throttle body.So we want to make sure we're on good and snug. We'll hook our 2 clamps on. And down here somewhere is our connector for the mass airflow sensor. Stick that on there. And we'll run that in until we hear that click. Throw the line back in there. Okay. And you're done. So we've taken care of our coolant leak. And you might need to add a little bit to your overflow bottle. You really didn't lose that much. But you want to make sure that that's at the proper level any way. So, when you find that water leak and you're ready to change that heater plate on the bottom of the throttle body on your BOSCH equipped 4.0, 4.6, either the Range Rover or the Disco, call any of our knowledgeable salesmen at 1-800-533-2210.And thanks for watching.
