when i got my cooler put on we both came to an idea do half the 100k service now and half later save on cost's ...oil - front diff, rear diff, auto trans oil , engine oil, oil filter, basicall all the fluids that looked old and coulnt wait .. but for that labour was only $240 parts was $148 .. in 6km more im getting timing belt and sparks done and change air filter and maybe fuel filter .. this is at a well reconized workshop also
