Hi today I learned my 2000 landy D2 has a spraying leak from the coolent on the drivers side where two small hoses come to meet.. It starts over heating if I drive it 5 miles now my question is do I need a new hose or new block where the hoses meet or can I get a sealent for it, or just tighten it? That is the best I can explain it. Thsnk you in advance.

 

Are you talking about the two small hoses near your throttle body?

 

Snip off about 8mm on each and remount.
You may need to get a new hose clamp as those hose clamps are pressed on.

IF still leaking, you will need a new throttle heater unit.

 

see Throttle Body Heater Plate Kit (Genuine Part # MGM000010) | Land Rover And Range Rover Fuel System Parts

And bypass (hose to hose with double male splice from parts store) or deal with it promptly, you will be lucky if overheating has not damaged engine (head gaskets, slipped sleeve). By overheating, I mean well above 50% on the gauge. If at end of scale or red light on, very bad sign. If you plug in an Ultra Gauge, you can watch that temperature and react before the factory gauge even goes off normal.

Many Discos are in the salvage yard because someone drove them when hot, thought they could make it to the next exit, or back home, etc. A case of bottled water in the cargo area is cheap insurance. Distilled would be better. It removes the temptation to keep driving before dealing with overheating.

 

Make sure once you repair the t/body pre-heater hose leaks that you bleed the system or you will over heat your engine.

 

OK here is your homework assignment:

1) Bypass or fix throttle heater as per Savanna.

2) Bleed system as per Mike

3) Avoid engine damage by dropped sleeve or bad head gaskets.
You just don't want to get to step #3.

So, this assignment is due now.
