Throttle body heater bypass

Throttle body heater bypass
I changed my throttle body heater plate out last night from British Pacific, still leaks. I also used some permatex RTV when installing, lighty sanded the housing to ensure all old crud was removed. I have looked online for about and hour and all I can find is that it can be bypassed with no serious issues or threats to my LR. However, there isn't a diagram or a step by step that I have seen. If anyone can provide or point me in the right direction, it'd be appreciated. Thanks in advance.

Here is the plumbing flow chart. Keep in mind the purpose of the device is to prevent the throttle from icing up and sticking in one position. May happen in certain weather conditions at slightly above freezing. Won't happen in Planet Houston in July. But could during a cold snap. Or if you went on a trip. So worth fixing, but you can bypass to keep the truck usable. Don't just stub off each pipe, couple them together because some of that coolant flow is used to make the thermostat open at the correct time. Makes no impact on mpg, etc. Note that anything plastic or rubber under the hood has been baked and decomposed by oil vapors, and can be brittle. Easy to crack, another trip to parts store in another vehicle.

drowsapp, Savannah Buzz and willrok13- Thanks, the kit I have from BP uses a rubber gasket, after tightening down, its not flush with the housing, I haven't cranked the engine over since but, did squeeze the upper radiator hose and coolant squirted out. I feel the bypass is the best fix. Now what do I do with the 2 lines coming out of the plate, just use some hose and connect them to each other?

You dont have to do anything to the throttle body if you connect the reservoir to the hose coming out of the top of the engine. Coolant does not circulate there without hose #6 in the photo being connected, so just leave the heater plate totally disconnected. All you need is a hose for the reservoir/top hose connection. I have had mine bypassed since I broke the plastic reservoir pipe two years ago. No problems. Essentially, you will be connecting hose #7 where hose #6 exits the engine from the photo Savannah posted.
