Hi All,

Just out of interest has anyone else had a coolant leak?

I found this; http://www.fullfatrr.com/forum/topic4440.h...olant+leak
So will check this out, but if anyone else has experience of a coolant leak could you please share the outcome?



Also, what are peoples experiences with RR specialists?

I have taken mine to two different speciliasts, firstly for a air suspension inactive fault, where I was advised to buy two new rear air suspension sensors and a re-set at a Land Rover main stealer.
This was later fixed by myelf with a new battery, (I got the idea from someone on this great website)....

The second specialist I went to, this time for the coolant leak in question, I was advised that they couldnt really find the leak, they flushed the radiator and it wasn't that.
So there advice was to replace every single hose and the radiator (cost around £1100) and the best bit "we can go from there" pfff yeah right.... I just get the feeling these cars have a few niggling things but garages just seem to go straight for the big possible problems?

or am I just being paranoid?

cheers all!

I had a coolant leak and it turned out to be the Radiator top hose ... started off as a drip ... drip ... drip and then got gradually worse until it just turned into a tap.

All fixed with a £28 OEM replacement. African Bush Junkie ... in London!

the header tanks are prone to getting pin holes, and they can be very fine, i had one and it looked like a hair coming of the tank. 2nd the cap can leak,wrap some whit tissue around the neck and you will see if there is any leaks.. V8 facelift Range Rover Autobiography 22" wheels.

What gives you the idea you have a water leak? I don't mean in a derogatory way but what are your symptoms? Do you get a puddle under the car or does the coolant level drop in the tank over time? The 4.4 suffers from a few known problems. They are from most common to worst; rads are prone to go in the bottom left, hoses leak/split, header tanks crack, water pumps fail, transmission coolers leak, valley pans leak/weap and finally the head gasket. If you can give us some more details we can give you more help.

Sounds like the transmission is a dodgy sensor in the gearbox.
As for the coolant issue; how much are you putting in over a week? If its not pooling under the car, I don't think it's a massive leak unless it's a head gasket. When my rad started leaking I would loose coolant but had no pool due to the fan drawing the air through the rad and blowing the coolant over the hot engine. Eventually the leak got big enough that overnight I would get a pool. Do you have any white staining on the header tank?

thats quite a lot of coolant to put in each week.

have you tried some radweld sealer in the system to see if it solves the problem?

Had a waterfall on the front of my escort rad years ago, bit of radweld in and it ran fine for years.

one thought as you have a concurrent gearbox issue, do the petrols have an oil/water gearbox cooler, i know on the BMWs these sometimes fail allowing coolant into the gearbox oil. Unlikely though.

Personally I wouldn't use radweld untill I knew what I was sealing. 1.5L does sound alot. I would check all your hoses first and prob your rad. The 4.4 does have a water/oil cooler. Not heard of that happening but with FFRR ownership anything is possible. I would think with a leak that size it would be showing itself somewhere. Have you had any over pressuring or overheating? [img]http://www.fuelly.com/driver/rob2529/range-rover[img/]

On my 02 I had two separate leaks. The easy one was a cracked header. Difficult to see but the white staining was the clue and when I took it off it was obvious in the main body. The hard one was fixed at a dealer after much searching and was a small pipe hidden somewhere at the back of the engine. Very cheap part but huge labour cost to find/fix it. Both got through about the same amount of coolant as you suggest....but it will get worse. Also be very careful of overheating the gearbox...thats a whole other can of worms and even more expensive to fix. Good luck... Mike - MPx

I'll second the leak from the small pipe at the back of the engine. I can't remember the exact words my village mechanic used to describe how hard it was to get to but I'm sure you can imagine!
I had another leak as a result of the pipe from the bottom of the expansion tank getting too close to the bottom pulley and having a groove worn in it before I bought it. There was no sign of the leak under idle at first, hence why I didn't spot it. Cheap and easy part to replace thankfully.

I had a leak on my engine from the rear hose, very common problem. I looked for the leak over a few days then one day whilst driving home the hose let go and dumped about 3ltr of water out. The hose was an easy fix but you need to remove the plastic cabin filter enclosure which is attached by two bolts to the bulkhead. The hose cost about £15 for an OEM part, about an hour to fit. Range Rover 4.4 V8 Vogue

I had coolant leak behind lower radiator, and after two repairs with welding, I replaced it with new radiator. engine 4.4 v8.

Thanks for the suggestions all.

I'm going to un-plug the radioator drain plug, apparently if it flows out its all good. If it drips or slowly trickles out then its got crap stuck in the bottom, so hopefully this will eliminate the occasional transmission overheat message. An extra bonus would be the radiator is leaking coolant so two birds with one stone!

Yep, I had a leak for ages, but couldn't find it, sames as I was putting 1l in a week, but was told it cold be to do wit the LPG kit running hot and burning coolant

Anyways, then one morn I topped it up and it came straight out the bottom...... water pump, proper shot.
Had it replaced, week lated went agin, turned out to be faulty.
Whilst the car was stripped the garage found OAT coolant crust around the rad, which had corroded and that's where my small leak was

So water pump, coolant flush, oil flush and filter change, new rad, new thermostat, and full LPG service and recalibrate
