Hi I have just got a 4.6 Vogue and looking to put in on gas but someone told me that they have more chance of overheating on gas than petrol is this true or should i just go ahead and do it.

thanks

They only overheat when they have a sloppy install. You have to make sure you have a top of the range injected system. Buy a cheap one and say good bye to your motor. Things like fitting steel T pieces to water pipes prevents so many issues. The high temperatures under the bonnet constantly expand and contract the joints. This often distorts the plastic T pieces causing cooling leaks.
If you have a good system installed professionally then you’re on the road to saving money. The engine will run sweeter and rev a lot cleaner and above all it puts a smile on your face to pay 50-60p a litre for fuel.

Thanks mtecuk for the info do you know of a good place round the north west area to do the install.

I don't I’m afraid, but here is a good source of information. You can find a registered installer near you with the search facility

Some of these engines suffer from bad blocks because they have been over-bored, and done badly at factory, it seems that it is impossible to find which ones are good and which are bad, but with this fault the engines are prone to failure with cracked blocks and slipped liners. The extra heat generated by Gas could kill it.

Look up the section on rr and look for overheating, a couple of guys up on this have detailed these faults. Worth a look before you commit

Also make sure your cooling system is in good fettle.

That’s good advice but I always find someone always knows someone who’s had a bad conversion and a bad experience. With LPG installations it’s down to the install. If you have some yoyo throw a kit on and not set it up right and it runs lean, then the engine starts running hot. Couple this with a poor wiring job and a couple of dodgy water connections and bingo you’ve got yourself a dead Range rover.
If you have a professional install then it’s the best thing since sliced bread for saving on your huge fuel bill. There are thousands of range rovers out here running on gas. With the new injected kits, they map themselves dam near perfect to the injection duration and with a bit of fine tuning your good to go.
Another area that is as important as the install is the after service. How many times have you heard someone take an lpg car to a garage to get it serviced and they play with the engine, effecting the gas and then say sorry we don’t do lpg. That’s fine as long as you understand you need to have the lpg serviced as well as the engine.
Even if you take it to the lpg installer after a service and let them check it over. That way you’re guaranteed a perfect ruining vehicle. It often consists of nothing more than a once over with the laptop and a filter change.
Sorry I am going on. Let me know what you think on the subject.
The most important thing as with anything is the maintenance.

I agree, but still think you need to hope you dont have one of the bad engines.

Also you need to do your maths, will you recover the costs of the instalation during your ownership, or will it benifit the next guy.

 

[Mtechuk]

Yep that’s right. If your conversion costs are £1500 - £2000, then that’s a lot of petrol. That said doing 18-29 mpg it doesn’t take long at all. Its a diificult one.
You have also got the advantage of not braking into a cold sweat on long journeys in fact LPG enables you to take a range rover on a long journey.

i have just sold a 4.6 which was converted to gas with a bigas system and i ran it for 4 years and done over 50,000 miles with no problems at all and not a drop of water used hope this helps you

Thanks for the replies I will think about it
