Done with the throttle body heater, time to bypass. Parts list?

Also, I wouldn't delete the TBH, instead I'd use this. Have it on my 3rd Disco and ... brilliant, no issues.

As someone up above said, I blocked off a TBH once by just sticking bolts in the end of the line (removed from throttle body heater connections), then clamping off. And in less than 18 mos, both lines filled up with sludge at least a good 12-15" into the lines. This sludge could, I guess, get into the rest of the system. Connect them together and keep the flow moving...
It seems to me that in a well-maintained cooling system there will be no sludge anywhere in the system.

My take on the plug the lines method vs bypass entirely method - I often divide decision making into one of four quadrants:
1. High-risk, low-reward
2. Low-risk, high-reward
3. High-risk, high-reward
4. Low-risk, low-reward
This fix fits into the low-risk, low-reward category IMO and can therefore go either way. Its very little extra work to just remove the original water lines and replace with a bypass line, and by doing so removes two potential clamp failure points and I guess eliminate the risk (however risky it actually is) of accruing build up in the dead lines. It won't necessarily harm anything just plugging the lines either, but if one method is even a whisper of a margin better for such little labor, why not I guess?
Plus, the bypass method adds about 40 horsepower.

The base was very nice looking, on the unit I saw (which might have been from that other vendor you mentioned) the issue was with the two nipples and how they were poorly bonded to the base. Also the gasket was not rubber. It was like a cheap water pump gasket. I guarantee that puppy would have leaked or failed way worse than the OEM design & thats pretty bad in my book.
Glad you got some good ones & are happy with them. I just had to mention the 1 time I had one of those in my hands 3-4 years ago and I was not impressed for what they paid for it.

Help identify Coolant Leak Source
Hello all,
I have been trying to track down significant loss of coolant. I replaced throttle body heater, and took care of one of the leaks, but still losing a lot of coolant. I put some tracer in and I see a leak on the front driver side toward the middle. I don't see anything from the top of the engine. I was hoping someone could help me identify the source. With the engine running I could see coolant turn the corner right where this arrow is. Any thoughts?

You can pump up the pressure to 20 psi, and then inspect for leaks without having the engine running.
Good luck, and let us know what you find.
