I know. I have seen that very long post. All my Discos were bypassed very long time ago. First thing to do like replacing driveshaft. That small area there has 3 points to leak coolant. 2 hose clamps and the gasket itself.

I live in Chicago, spend a lot of time in MN, so I fixed mine. If I lived in a warmer climate I would have deleted it.
When I took mine off, I put a piece of very fine sand paper on a flat surface, and I sanded the mating surface of the TB. I saw this on a car show on velocity, and thought I might as well do that. Seemed like a good idea. It hasn't leaked to my knowledge. You run it across the sand paper straight, turning 90 degrees.

If a LR locks up in cooler weather they can park on the side of the road next to Hummer H3’s which did not come with a throttle body heater plate... I never heard of a single H3 having issues and several owners were in Alaska & Canada.
I do seriously treat that flaw with the throttle body heater plate like a D2 front drive shaft or swapping out the OEM thermostat for the 180F unit as soon as you buy a D2. It’s a deadly enough little leak to go undetected until ya peg out on the freeway at 230F due to no more coolant.
When I delete it I go all out!! I remove that POS from the throttle body completely, I take some new 5/16 coolant line from the intake to the reservoir and I slide on a 8inch long spark plug wire heat protector boot over the hose where it hangs over the exhaust by the reservoir. Almost 6 years now without a single issue after being completely removed on any of my D2’s.
