HYUNDAI TERRACAN: Questions and answers

Hyundai Terracan 2003

The 4x4 system on my Hyundai Terracan has stopped working. the the car still drives in 2 wheel setting but will not select 4h or 4L. I recently replaced the battery and got the polarity the wrong way round and ABS and the 4x4 selector switch have since stopped working. Has anyone ideas as to what the problems may be rectified. Many thanks. (2.9 CRDI)

Hi, there are two likely culprits causing this problem. The first is you may have blown a fuse in the circuit supplying the 4x4 switch. This may have happened when you changed the battery over. Just check all your fuse boxes under the bonnet, they are all marked inside the cover. There is also one fuse box behind the panel next to the drivers right leg. The other culprit is not so simple, this happened to me. The 4x4 is engaged by a selector pin that requires vacuum from the engine to operate a rubber diaphragm to pull it into place. This diaphragm is located in a small assembly attached to the front transfer case. If the system loses vacuum the pin does not fully engage. In my case the diaphragm was broken, its a repair by replacement, the whole unit is replaced. Its a simple repair job as its all held in place by a couple of bolts, easy to get to on a hoist. The diaphragm was actually partially working in my case. It engaged the limit switch attached to the actuator so the lights in the dash recorded 4x4 in operation. It did however not fully engage the locating pin for the gearbox so I kept getting bogged! I did notice if I reved the engine increasing vacuum as I operated the 4x4 switch on the console it did sometimes fully lock the pin in place. By this time I had made arrangements to replace the damaged unit. Hope this helps - Robert Dunlop from Australia

I’m using a lot of water from the radiator, I don’t know where it going or leaking. Any ideas? (Diesel 2.9L)

Answers

I hope the water is not entering the oil chambers, check this by checking the quality of oil. It should not be turning white. Otherwise the hoses lose water under pressure when the vehicle is running due to minor ruptuters. I have a Terracan, it is a wonderful beast. mosgate@yahoo.com - Parminder Singh from India

Does a Hyundai Terracan 2.9 CRD bend valves?

Answers

Inlet/outlet engine valves tend to bend in case the timing belt snaps away or turns loose to change the timing order. A periodic check is most recommended for all diesel engines - Parminder Singh from India

Can anyone tell me if the Terracan has a selectable differential lock?

Answers

No, it does not have a selectable, it has two wheel drive four wheel drive high which must be selected below fifty miles per hour and it has four wheel drive low whitch must be selected when the car is stopped. I have driven a Terracan for 5 years now and have never been stuck in mud or snow and that’s in 4 wheel drive high. It does not like dry roads when it’s in four wheel drive but can hit speeds of 100 mph in two wheel easy, and tows well. In 4 wheel low all four wheels lock up and if you get stuck. The mud or snow must be up to your windscreen, don’t believe all the rubbish you hear about them, it’s not true. I know, I have driven different makes of 4x4 and I have owned a G wagon and the Terracan is right up there with the best. It’s old school, it’s Korean company owned by Mitsubishi. Take another careful look at the shape off the car, it looks like a Shogun. Ta ta the noo - Steven Smith from Mid-Lothian (Edinburghshire)

I have a 2004 2.9 diesel auto and love it only I’m only getting 18mpg. Is this normal? It is serviced regularly.

Answers

No. I get 25mpg and I do not drive it carefully. A mixture of on/off road/motorway/A roads. It does drop a lot if all I do is running around town. Interestingly it does not seem to drop when towing so it makes good use of the torque and power - James Dell from Bedfordshire
