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.
And to further play devil's advocate, I've bypassed the throttle body coolant lines on my SHO for going on 8 years, and during the years where I did winter drive in that car, I never once had the throttle ice over on me.

I'll agree, with the caveat that if you live in a region where temperatures don't fall below 20F, there is no risk of throttle plate icing.

Well, i cant make you believe anything you don't want to. But its there for a reason and i hope that nothing ever happens to you or anyone because of this cheap cheap decision of yours. Temperatures are changing all over the world and there is no telling what this winter will bring your way. Just keep that in mind and always remember those small little changes you made and if the temps do get colder in the areas that all you rebels live in the possibilities are there no matter how big or small they are. Be safe!

bypassing throttle body heater plate DONE

I live in Vegas I think bypassing this troublemaking throttle body heater plate will greatly increase my fuel efficiency.
I already bought a new throttle heater plate & gasket kit from Atlantic British just so you know.
Discovery II has many bad design on parts: front crank seal, upper radiator hose bleed screw, throttle body heater, expansion tank coolant hose, oil separator, head gasket, and more.
This is why use ones are dirt cheap.
But I enjoy fixing cars on weekends rather than going to casinos : )
Thanks a lot for your advise.

I think it would be okay to give it a try if you wish. I don't think it would have much of a difference on you mileage.
I have just changed my factory throttle body heater plate at 102,000 miles and i think it served its purpose for long enough. Any vehicle you buy will have parts that will fail sooner or later and not performing proper maintenance will cause parts to fail sooner than later. The discovery has a fairly strict maintenance schedule the better it is followed the longer it will last. I agree dex is a horrible product to maintain and will cause big problems if neglected. A totally screwed up coolant system and overheating is common with a neglected dex system. The head gaskets are okay as long as you don't let this engine get hot. Put it this way i have 103,000 miles and the only part i have replaced on my truck from failure is this throttle body heater plate. I have owned this one since new and have taken care of it to the T i am still running the factory coolant hoses i only put land rover fluids and parts on it. Has new wires but they are factory and i changed my front prop shaft. Everything else is stock and in excellent condition. I love my rover!

I can see replacing the gasket instead of bypassing to preserve factory-correctness or for someone living in the arctic, but given the failure rate I'm thinking the bypass is a safe bet for most.
It will start to form on the fronts of your mirrors, your grill, etc. and when it is doing this it is also forming on the air intake.
Why do you think the MAF sensor wire is heated?
If you live where it gets cold but the humidity level is always low, not likely to happen.
Live somewhere it not only gets cold but it also humid, very very likely to happen.
Good read. Obviously the TB heater is useless in temperate climes and it appears the consequences of ice in our mechanical throttle bodies are not likely to be severe (won't get stuck wide open as ice only jams it from closing that last bit).

You say it snot big deal, until you tap the brake to turn the cruise off and you dont slow down, or you try for that panic stop and you keep barreling on at 70mph.
Its no big deal until it is.
You wear your seat belt but you've never been in a accident, so do you stop wearing it? Even if it was not law would you still wear it?
If you could buy a brand new car with no airbag would you?
