Thanks mate. Will have the alternator checked out. thanks for taking the time to reply.
I would be switching the extra fan on for low speed work mainly, eg, stuck in traffic or low range off road. Would also help when towing as you mentioned. Over about 70km/h it would have only limited if any benefit.Quote:

It could also be the fuse for the gas to petrol switch, i had a loose wire and it will make a noise and a wire with to much current goong through will get hot!!
Additional fans are usually fitted to help cooling while towing,especially up hills
Hi Guys,
Today I done an oil change, and after I did it, my car makes a whining noise, predominantly at gears 1,2,3 and 5. On Gear 4 the whining noise is non existent.
I have taken note from previous posting, thinking that it maybe the alternator, as I do have a dead battery being charged by the alternator a bit too much lately... (time for a new battery)
But I can't help thinking that it could be either one of my own thoughts about the problem...
1: too much engine oil?
2: Is the gearbox low on oil and if so how can i find out?
3: Could I have done something wrong during the oil change.
Please help!
I take it from point 1 that you changed the engine oil?
The noise you describe is coming from the gearbox. The reason you can't hear the noise in 4th is because that is the only gear that does not actually use the gears in the gearbox, it's direct drive-input and output shafts locked together. It is most likely caused by either worn gears or bearings (or both). I can only guess that you are hearing the noise now because the engine is running a bit quieter after the oil change.
Check the gearbox oil by removing the fill plug in the side of the gearbox. It's about half way up one side (I can't remember which side) of the gearbox casing. The oil should be level with the bottom of the fill plug hole. Check the transfer case oil level the same way while you are under there.
Replace your battery ASAP. It won't do the alternator any good constantly trying to charge a dead battery. An alternator that is working hard will make a whining sound that can be heard easily in the engine bay with the engine at idle or just above. Will be a bit harder to hear with diesels.

Yep I changed the engine oil
Hi,
yep I just done a simple oil change and now I have really stuffed things up.
I was reading online that over filling the oil actually damages the engine.
As I don't have a GQ Patrol manual readily available, could someone please tell me how much engine oil is needed? (6 cylinder, 4.2 Litre Diesel) from a GQ 1990 Patrol.
I really cant believe how a simple oil change, after all the other things I modified on my vehicle, is the one to get it undone.
I put in 9 litres of oil yesterday. and today I went to drain the engine oil, and nothing comes out! I mean it was not leaking oil from the 20km I driven. and it wasn't burning it up because there was no black smoke from exhaust.
Oil amount is best checked with the dipstick
With the workshop manuals here i only use fluid levels as a guide
9L of oil gone from a 20Kl trip ???
If its not on the road,or excess black smoke (ya dont want this either)
Check under the car on the floor,if its wet , theres your oil
The only way to over fill oil is using oil amount as gospel
4.2 Diesel takes "about" 11 litres to fill if you replace both oil filters, but as MQ MAD said, fill by the dip stick.Quote:

Or is it just that when you checked the oil level on the dip stick it was dry? 9 litres of oil is a LOT to loose in 20km, there would be oil every where. Oil smoke is blue.
