Disco 1 Baseline - Check My To-Do List

[onewhippedpuppy]

I've had my D1 for a few months now and have fixed the broken stuff, now I need to perform a good baseline to make this a vehicle I trust to drive anywhere. Basic stats are 1997 Discovery, 105k, mostly daily driver duty with some light to moderate trail use planned.

Stuff that's been done in the last year: plugs, plug wires, thermostat, front wheel bearings, CV joints, lube in the transfer case and diffs, transmission fluid, radiator, water pump, coolant tank, anti-freeze, temp sensor, fan clutch, serpentine belt, and air filter.

Stuff that I'm planning to do: power steering fluid, brake bleed, fuel filter, O2 sensors, coolant hoses, PCV filter, ATF filter.

So, what am I missing?

 

[achampagne]

change out all the heater hoses, thermostat, rad hoses. I just learned the hard way.

 

[Rovertrader]

at least check the oil cooler and trans cooler lines

The fuel pumps are known to fail and with the age of yours it might be a good idea to change it out.

Agreed. If the fuel pump housing assembly is in good shape you may be able to do what's affectionately known as the "cheap bast*rd" fix. It's where you replace just the pump itself.

I'd go down the list of items listed under the 160k mile maintenance in the PDI and Maintenance manual, with the addition of the two items from the 60k mile service that aren't included in the 160. Skip replacing the catalysts unless they are needed. Also the items mentioned at the bottom of the schedule.

Any particular reason you're ignoring the rear hub bearings?

If you can't get new grease to come from around all 4 seals on each u-joint when you lube them, replace them.

If you're not having any faults I see no reason to replace the o2 sensors. It's worthwhile getting a set of NTK from Amazon as spares as you'll need them eventually.

If you have a black coolant overflow tank it's a good idea to pick up a translucent spare. The black ones are more prone to cracking.

Good advice, thanks guys.

Regarding the rear hub bearings, I'm assuming that like most bearings they'll give adequate warning when they're going bad. Is that not the case?

I have a 95 D1 5spd, but I will give you my list of what I have done maintenance-wise and what I'm planning to do. If nothing else, just for the sake of comparing notes. (some things may or may not apply to yours)

Done:

-Radiator hoses
-Heater hoses
-Spark plugs
-Cap/rotor
-Thermostat
-Flushed radiator
-Upgraded the black expansion tank to a clear one
-Air filter
-Injector o-rings
-Valley gasket
-Oil pressure sensor
-Coolant temp sensor
-Serpentine belt
-Alternator
-Brass radiator cap (replaced plastic)
-Valve cover gaskets
-Fuel filter (replaced with non-threaded VW Bosch part)
-Fuel pump
-Misc bulbs and waterproofed all connections

To do:

-Exhaust gaskets (head to manifold and manifold to exhaust)
-magnetic drain plugs in diffs
-change diff fluid
-tranny fluid
-trans case fluid
-swivel ball seals (and probably wheel bearings while I'm up there)
-oil pan gasket
-clean pickup and check bolts
-oil change (waiting to do the pan gasket for this)
-lube all u-joints and drive shaft points
-flush brake fluid
-flush clutch master cylinder


I think thats about it as far as maintenance items go. The rest of the things are body issues, such as fix a window track that is messing up, etc.

If I think of anything else I will let you know. Hope this helps some.

Majorpayne that's a great list, thanks. Was that all PM, or was a portion of it because of necessary repairs?

Hub bearings are a maintenance item, more so if you off-road. If you maintain correctly them they will last for well over a 100,000 miles.

The vast majority were just maintenance items. The alternator for example was necessary.
