Preventative Maintenence

Just wondering what preventative maint. i should have done on my H2. I get it pretty dirty in the mud etc. What fluids should I change and what intervals. I have 44k miles on it right now. Also what seals etc would need changed with those related fluid changes.
thanks

I have found that the 100000 mile Dexcool needs to be changed at 50000 miles if you want to keep your head gaskets .

Make sure it's lubed/greased regularly....:) If you do a search on here, there is a thread that shows all the grease zerks and where they are located.
