Well RT would have given your car a rudimentary service. He was going bust at the time and wouldn't have spent anything he could have saved on the car I'd guess! So the car has a recorded 30,000 mls. For me I would change all oils and fluids. Firstly always change your engine oil and filter annually. Once you have heated the oil to operating temperature you are on a 12 month maximum time slot.
If you don't have an in-depth service history or access to a previous owner then who knows how long the gearbox and diff oils have been in place, also the coolant. The header tank might look clean and the fluid clear but use a proper flushing agent and method and watch what comes out! These operations above are the best and cheapest way to look after your MOG and ensure longevity without huge repair bills. Check the tyres as well for condition and age, tyres beyond 6 years old regardless of use are now in the too old category and could well be dangerous. Lots has been posted here previously on all the above with many recommendations
I have a 2010 plus 4, so more or less identical to yours. My service regime is:
Engine oil/filter.......................every 12 months or 5000mls. filter Fomoco or K and N.
gearbox..................................correct grade as stated in your handbook. 5W 40. 5000mls no time
differential...............................correct grade. 5000mls no time.
coolant....................................correct grade, pink type. 50/50 with distilled water. system holds approx: 10lt. annual check
for state of coolant. probably last 5 years but expect to change from 2-5 years. Chemical flush though
prior to this change.
brake fluid Change every two years by bleeding the full system.
Clutch fluid you have the MT-75 Ford gearbox fitted with a concentric clutch. These are tricky to bleed. You will find
find a bleed nipple on the top of the bell housing just below the front bulkhead however as a minimum
suck the fluid out of the clutch reservoir with a syringe, all of it and refill with new. This tends to keep to
keep the fluid clean enough without disturbing the vulnerable concentric clutch mechanism.
Think the reference to 5w40 refers to engine oil rather than gearbox oil? Think typing may have slipped a line? ( But, there again I dont have a MT 75 box.)
