Just purchased a 2003 L200 Warrior and am looking for any suggestions as to what I can do to make sure it lasts. It is running fine right now and want to keep it that way.

It came from a dealer, but I have no idea what was actually done so I want to at least change the oils, so I am looking for preferences and recommendations. Any additives? Anything preventative for the head gasket?

Cheers

Spray it all over with WD40, wrap it in cling film, park it in a garage, DON'T drive it. It should last a few months before . or

Seriously though. I'd change all filters, oil, fuel, air, engine oil, front and rear diff oil, brake/clutch fluid, gear and tranny oil, flush the cooling system and re-fill it, check all the nipples take grease and do them, people seem to forget about this and Bang some STP ultra in the fuel
You'd be off to a good start, then just sit back and wait for the inevitable
Decent coolant and decent oil will help with head longevity, and of course not razzing the tits off it helps too.
Truth be told on all three of mine it was no 3 big ends that went , rather than the head.

Thanks, that was a much more helpful response. I was curious if people has found any benefit, or detriment to using synthetic oils in these older models?

As to the removal of the EGR and cooler...seems to be lot of pros/cons on both sides. This is a 2003 Warrior, so from what I have read, the system wasn't really designed with it in mind, rather it was added to make the green people happy. Any issues with blanking it off, but leaving the EGR in place so it looks unmolested for test? If I blank the EGR, should I also bypass the cooler, or leave it alone?

Thanks.

There has been anecdotal evidence that the cooler can go porous and allow exhaust gases into the water . You could blank egr and refit so it looks like its there

If you put a wee blanking plate under the exhaust end of the EGR pipe too that'll stop any exhaust gas issues, even if the cooler does end up being compromised. Not having the cooling system running through a well of hot gas should slightly reduce the overall coolant temperature too.

oil changes every 5k on the speedo....apparently the temp gauge never moves from quarter past nine. even when towing. The same grease nipples get greased don't ignore the rest..They seam very unpredictable re problems..Stay strong Nik

Thanks for all the suggestions, will be getting into it as soon as the weather gets a little better.
