Throttle body gasket replacement question

I just got back form about a 200 mile road trip in my sorta new to me DII. I noticed a small coolant leak from the rear valve cover gasket on the drivers side. Upon further inspection It looks like it is actually leaking from the TB gasket, running down the valve cover and getting trapped in the rubber "lip" of the vc gasket. I am going to my dealer tomorrow to pick up the gasket kit, wondering if I need to replace the 2 hoses also, as they look really hard to get to without removing the intake.

Also I have heard about a bypass by connecting the 2 hoses. I live in the ohio river valley climate, coldest it would ever get it 0*F, and that would be a stretch. What is the best way to take care of this?

Thanks, Nathan

replace the gasket... also get the throttle body gasket, easier to replace the TB gasket with the throttle removed.. buy some small hose clamps to replace those stupid quick clips..

don't bypass it... if ever your throttle ices over, it's not good..

Just change the gasket. Its as easy as can be to do. Disconnect the two hoses off of the TB heater plate. Then disconnect the CC and throttle cables. Remove the 4 screws holding the TB on. Once the TB is off you can change the TB heater plate gasket.

All you'll need to buy is the TB heater plate gasket (may come in a kit with new heater plate and screws) and a TB gasket. It seriously takes like 15 min to do.

FWIW, I've never had a problem with quick clips.

I will get the both gaskets. Thanks guys. Looks like the PO replaced the quick clips with screw style clamps already.

You don't even need to remove the throttle body to replace the heater/gasket. Just remove the intake/ airbox lid and remove the three 5.5 mm bolts into the throttle body heater.

Replace those hoses as well because the become very brittle and break easily. You can either buy the two hoses from Land Rover (about $50) or just make your own. Just pull hard on the hose under the plenum and it will come out. If you can't get it out either cut it or remove the CC/throttle cable mount.

X2, I did mine no problem at all with the TB on. Just remove the hose right under for better access....

I took my heater gasket loose, cleaned the precip off and used some silicone on both sides of it. Didn't even need to buy a new one. And listen to jymnmiejamz about those hoses!

I need to have this done as well, only after some 20K miles after a new kit was put in:(. Sorry if it was beaten to death, but now that I want to do this myself, I am worried about loosing coolant and worried about those cables... (well, I can see now that it may not even be needed to mess with cables), but isn't the cooling system pressurized? So once I disconnect the hoses and remove the T/B, am I going to have coolant spraying everywhere? Also, I bought the loong replacement hose for the Cruise Control pump, would it be suitable to cut replacements for the two hoses from it? From the looks of it I may need some harder ones?

Loosening the cap on the coolant expansion tank takes care of pressure.

Cool, thank you thank you. Now, is there a need to "burp" the cooling system after the procedure in any way? Or do I just add up the coolant back to the normal level and be done with it?
