Changed mine last week using these instructions. Thanks for the details. I am lucky as I did not have any build up from dex cool. I do think that I will play it safe and replace the coolant hoses with my next parts order.

 

Just changed mine as well. Thanks for the instructions. Even though it was a straight forward job, it was nice to have a reference.

 

Just finished this repair on my 2003 DII and very much appreciate the great instructions and photos. Since I live in a small town in Colorado, I ran into a few "gotchas" that cost me a little extra time and frustration.

1. Ordered the replacement plate/gasket kit from Amazon (http://www.amazon.com/APA-Throttle-B...2606655&sr=8-1). Shipping was free with Amazon Prime and it actually arrived overnight due to the product originating from Denver. Bonus!

2. The 5.5mm socket to remove the original plate was not in my arsenal of tools and was not stocked by either of our two auto part stores, the hardware store, or our local Sears outlet. Luckily, a guy from Sears let me borrow a 5.5mm socket from their workshop... but chalk up two trips to Sears to retrieve and return the 5.5mm socket. The new kit includes 7mm bolts with the same threading which work nicely with standard socket sets.

3. As mentioned in this and several other forums, I broke the brittle plastic coolant line from the expansion tank to the throttle body. This was easily replaced by some 5/16" heater hose from Napa, but required another trip to the store. I took other the advice of others and replaced the standard hose clamps with worm screw clamps.

4. The new kit has a gasket that is all rubber (or similar substance) and does not have the metal inner core like the original gasket or the replacement gasket posted in the original pictures of this thread. One side of the gasket kept popping in or out upon even modest tightening and it took me a few tries to get the gasket seated properly.

All in all, a pretty simple repair and a majority of my repair time was spent driving to pick up the socket and new hose.

Thanks to everyone for posting all of these great instructions and follow up tips!

 

5.5mm = .2165"
7/32" = .21875"

.002" is nothing

Sounds like 7/32 socket should work. Is it 12 point like the Rocker Cover bolts?

 

Ah... I like the math! I tried the 7/32" socket but it had that bad feeling of slipping on the bolt head. It could just have been that everything around the plate was covered in slimy dexcool, or that I was doing it upside-down without removing the throttle body... but I was scared that stripping the bolt with the 7/32" socket would have turned a simple repair into a bigger headache. The 7/32" probably would have worked if I tried a little harder. Thanks!

 

I want to sincerely thank each and every one of you as senior members and moderators. What you post here is so incredibly helpful.

I am a first time used DII owner with just over a year with the vehicle (2001 DII SE) Moreover I learned to drive when I was 27 and this is the second car I personally have ever owned (I am 42). I am a mom on my own with zero car experience but so far have I replaced a few hoses and did the heated seat kit on my own. A trusted mechanic has replaced the alternator, coolant reservoir (a convenience more than anything else), and cleared multiple system issue messages.

I post because the coolant system keeps popping up with issues, and this forum has been an amazing guide and reference. I admit, i use rubber gloves to somewhat salvage the manicure, but I just performed the heater plate bypass on my own with some copper pipe and new clamps (and an epic knuckle bruise) just to get the Rover running again -thanks to posts by Disco Mike and several others- right before Christmas (no low temps yet so I deem it an acceptable temp fix). Local Napa got the replacement throttle body heater kit part in same day for $27. Better than any dealer (wish they could do that with windshield wipers, but I will pick my battles) I am about to embark upon replacing the offender with the new kit and this tutorial. I snowboard with my young sons and can't afford braking issues or any issues with ice in my manifold so replacement is necessary.

Oh, and I am buying the ultra gauge. I believe this is a $70 must have for anyone who doesn't carry sophisticated system message technology with them as part of their daily road gear.

Thank you again and again and again. Not sure how long I can survive this ongoing "project" but so far it has been life experience that I cannot put a fair price on.

 

Buy a set of wiper arms for a 1994-1998 Land Rover Discovery, unbolt yours, bolt on the new ones.
Then you can buy wiper blades anywhere and you can buy ones that fit your budget then too.
You just need to buy 2 of these.
Wiper Arm - Front | Land Rover Electrical Parts, Batteries, Relays, Lamps & More
You can also buy used ones off of e-bay, just make sure they are for a DI and not a DII.

 

I think Josh eventually bypassed his throttle body heater plate. He lives in the VI so it may make sense. Pls. correct me if I am wrong as I'm trying to dig thru all the info.

 

Hi I need to bypass this throttle body heater plate, can anyone post some pictures? Thank you guys!

 

Bypassing this could be a life threatening mistake and should not be done. The new gasket and throttle body heater plate is a $21.95 part from Atlantic British even comes with new bolts! and takes all of a half hour to change. That to me does not seem worth the injury you could cause to yourself or others. Half-assing things in life will never get you anywhere in life.
