Thread: Slipped Liners in a KV6

you have my sympathy

my truck is booked in for an early feb walletectomy as well so i feel your pain...

Thanks, Incisor I read your thread on a strange noise in your Landrover, we can cry on each other's shoulders, Ah, the joy of Landy ownership.

Couldn't wait for All fourX4 at Kotara to look at my vehicle so I took it to my local mechanic who I have been dealing with for years. Reasonably good news (better than an engine transplant) the transmission cooler for the Jatco Automatic transmission is cactus causing the auto transmission fluid to mix with the coolant, cost of repair about $1100 as compared to $10,000 for an engine transplant if a cylinder liner had dropped (phew). Has anybody experienced this before? I am sure it has happened!!!
Absolute TOP priority now is to install a low level coolant alarm. By the way, another worry, does anybody know if water has got into the auto unit (driven at the most about 5 kilometres after the problem was recognised) would it do long term damage? My mechanic said he will do a multiple flush of both the coolant system and the auto box before filling them up with correct fluids.

Yes have seen it before. Coolant can enter the Auto. But a few flushes will get it out. I would look at fitting a air blast cooler from a TD4 auto, V6 don't have them. they are a better cooler designed for hot climates and have no coolant running through it. Make sure it is the correct fluid incorrect will bugger this auto

If the heat exchanger in your auto box has corroded through - I would also be concerned about the heat exchanger in the IRD as well.

If your auto has to come out then I would check the IRD but if the box stays in then it is not worth pulling the IRD out. I would be regularly checking the IRD oil every few thousand Km - it goes milky green (assuming you have green lubricant.

The auto coolers on v6 usually crack so it's probably not corroded

With 80,000 km of mostly short distance driving, our 2002 FL1/KV6 has been using a lot of coolant (around 400ml daily for past 3 - 4 months) although without any sign of coolant mixing with oil or leaks from the cooling system. We suspect a problem with liners, even though this engine has never overheated.

I'm curious to know what options there are in a situation like this. Are new engines available from LR? At what price? Are reconditioned engines available? Has anyone converted their FL1 to electric? I would be happy to convert to electric (not hybrid), as we do mostly short distances, and understand it may be an option, but money is the issue there.

Welcome any information anyone can offer.

Mine was doing the same thing and as the rest of this thread has revealed it was the Auto box cooler that failed letting coolant into the auto box. I am having my transmission rebuilt as we speak as it did eventually fail. I have been quoted up to $5000 depending on how much damage has been done. I am also having the cooler replaced with an air cooled one, like the diesel Freelanders use, so I won't have that problem again. Good luck!!! Check the coolant overflow container for any sign of sludge, if it is there, thats the sign that coolant is getting into the tranny!!!
