Landrover transfer case leaks

follow the top radiator hose to the engine , the thermostat will be housed in a casing that the top hose joins to , the housing will have 2-3 bolts that need to be removed to gain acces to the thermostat, when fitting new thermostat ensure it is fitted the correct way round , take a picture of the old one before removal then you can't go wrong , ensure you have a new gasket to fit as well and make sure the two faces of the housing are completely clean of the old gasket material as otherwise you will get a leak , hope this helps

This is the kickdown adjustment

Check and see if head gasket is leaking.

Transfer case pump can wear through case and loose it's oil. After a while, gears wear out .

Crawl under and look at the top end of transfer case, just above drive shaft....see a little hole ?


If so, you have joined the 'Pump rub club'.

Go to Google and search = 'Pump Rub'.

You're going to have to pull the transfer case, disconnecting it from the driveshafts etc. I would use a small motorcycle lift / jack once disconnected to let it down, but other than that it's not that bad of a job. Is it leaking from the output shaft seal? if so there are two / front and rear get the set with both and just do them both at the same time since the case will be out anyway. Replace TC fluid after re installation

first remove both front and rear driveshafts. Then remove skid plate underneath transfer case. Remember to unplug the electric motor wiring harness for explorers with electronic four wheel drive switching. Remove vacuum line on the top of transfer case. Unbolt Speedometer cable mount from top/rear of transfer case. Remove five bolts connecting the transfer case to the transmission, this step will cause some transmission fluid to leak from the shaft housing (approx. half a litre) so place a drain pan underneath. Remember to either place a jack or wood blocking under transfer case before removing the last bolt connecting the transfer case as it is heavy (approx. 80-90 lbs.).

To install:

1. Apply sealant at the point where the engine block meets the oil pump.
2. Use a new gasket and install the oil pan. Tighten the mounting bolts to 8.9 ft. lbs. (12 Nm).
   
3. Install the front plate.
4. Install the front exhaust pipe.

Turbo Engine

1. Disconnect the negative battery cable.
2. Safely raise and support the vehicle.
3. Remove the front exhaust pipe.
4. Remove the exhaust pipe and muffler assembly.
5. Drain the engine oil into a suitable container. Once the oil has drained completely, tighten the plug to 29 ft. lbs. (39 Nm).
6. Remove the dipstick and tube.
7. For AWD vehicles, remove the transfer case assembly as follows:
   1. With the propeller shaft still installed, remove the transfer mounting bolt.
   2. Insert a suitable prytool in between the transfer case and transaxle, then remove the transfer case from the center shaft.
   3. Remove the transfer case from the center shaft. Do NOT tilt the transfer assembly to the rear or oil will leak out.
   4. After removing the transfer assembly, insert tool MB991193 or equivalent, to prevent the oil from leaking out. Use a piece of wire to suspend the transfer case from the body.

Good luck (remember rated this help).

a common problem is the intake gaskets will leak between the cylnder head and ihe intake

Remove the transfer case and replace the adapter housing seal

You mean between the case halves? It is just silicon, no gasket. These are good for the pump wearing a hole in the rear housing and leaking oil. The cure for it is a new rear housing and a piece called a case saver that keeps the pump from doing it again. Taking the transfer case apart to fix it is easy, I can tell you how to do it.
