Reviving this old thread as have seen some renewed recent discussions about coolant fluid.
Land Rover maintenance schedule reads that the coolant fluid in a Puma needs to be changed after 200.000km or 125.000miles. In my case that will probably be well after the SVX will turn 15 years old. That prescribed interval still seems pretty long to me, and I have read elsewhere some comments that the coolant fluid with is additives, etc. does age, and that its anti-corrosion effects will disappear, etc. So what to think? Leave the original coolant fluid in as per the book, or does it make sense now that the truck has 5 years/65k km to change it? And if it is better to change it, would this be a big job for a main dealer, or is it a matter of flushing the system and replace with new, eventually make sure that there are no air pockets, etc? Or is it a cumbersome job for them? Interested to hear opinions. Tks, Eric You never actually own a Defender. You merely look after it for the next generation. http://youtu.be/yVRlSsJwD0o https://youtu.be/vmPr3oTHndg https://www.youtube.com/watch?v=_GtzTT9Pdl0 https://www.youtube.com/watch?v=ABqKPz28e6A https://www.youtube.com/watch?v=rLZ49Jce_n0 https://www.youtube.com/watch?v=XvAsz_ilQYU https://www.youtube.com/watch?v=K8tMHiX9lSw https://m.youtube.com/watch?v=dxwjPuHIV7I https://vimeo.com/201482507 https://www.youtube.com/watch?v=ZSixqL0iyHw |

Average milage / year is normally take at about 12,000 miles. As the handbook gives a milage rather than a time interval for changing the coolant then I interpret that as meaning that high temperature i.e.: > 80c causes the coolant to lose some of its properties over time so time spent >80c/milage is more important than age of coolant per se.
Mind, you are being very optimistic that in 15 years you are not going to have to drain out the coolant for some reason! Don't forget, it is a Land Rover.   LANDYWATCH

Don't seem to be able to get much of a clear answer to the original question.
Can we wait until the Puma has 200.000km or 125.000miles on the clock, irrespective of its age, before replacing the engine coolant fluid? Which is as per Land Rover maintenance schedule. Or is the Land Rover maintenance schedule a bit optimistic about this, and would it be better to replace it earlier so that the effect of all additives (anti corrosion, etc.) remains in good working order? Especially for trucks which do only 10.000km or less per annum, meaning coolant fluid would be changed only after 20 years or longer. Any educated tech advise? 
And secondary, is it a big and timetaking job for a main dealer to do this? Tks, Eric You never actually own a Defender.

Maybe a good question is "what are the signs that coolant needs to be replaced?" 2009 110 XS Station Wagon

Different brands of coolant have different life expectancies. Some brands will say change with the onset of the second winter while others give longer. As far as I know the stuff used in the Puma is recommended for a change at 200,000 kms or 7 years. Manufacturers will also have a built in safety margin for the performance of the fliud, in this case coolant. What you need to be careful of is topping up. If you top up your long life brand with a brand with a much shorter change interval you could dilute the strength of the origional fluid. This would only occur if you had to top it up continuously over it's operating live.
Anytime I'd a coolant change on the tdi it was just a matter of loosening the bottom hose and letting it run out then refixing the hose. 1982 88" 2.25 diesel 1992 110 200tdi csw -Zikali 2008 110 2.4 tdci csw-Zulu 2011 110 2.4 tdci csw-Masai |
