So I groomed polished the disco, I’d rather drive but the lockdown is on, so I thought what can I do with my time, I could shop for some preventative maintenance stuff.
i have looked at a few threads and posts, at 127 k after a service , should I start at hoses and replace with silicone ? And buy a kit off amazon ?
I see a few comments on pcv valves, I had that done on my golf twice, so that maybe.
where do you start as an educated idiot ?
thought I’d get the trans serviced as well, and maybe the diffs

 

Don't do the tranny. If it ain't broke, don't fix it.

 

I mean I’m not the most experienced but I will say I hate the idea of lifelong oil. Trans oil and filter cost me like $75 and an hour of my time. Super easy to do, just hit the bolts with penetrating oil for a few days before and use a 1/4” drive ratchet to remove.

PCV mod is super easy, I believe the thread on the process is a sticky.

Differential and transfer case are also easy and about 80 bucks in oil. I used a 1/2” drive ~6” extension for the transfer case and the differentials are self explanatory.

Black 180 thermostat if you haven’t done that would be the first thing I did as well as the green coolant swap.

and front driveshaft greasing or refit with the grease fittings is a good one too.

 

Here is my recommended list of first things to do:

1. PCV mod to prevent oil leaks
2. Inline Thermostat Mod to prevent overheating - check with Jason Feuerstein, he recently did this and was surprised it does not get over 185.
3. Replace all original cooling system plastic or rubber components to prevent overheating and head gasket job
4. Sunroof leak issues - search my post - prevents headliner issues.
5. Coat CPS cover with aluminum foil to prevent CPS failure.
6. Remove door panels and lubricate window regulators to prevent common failures.
7. Lubricate cargo door handle to prevent rust seizing
8. Lubricate door straps to prevent popping
9. Coat rear frame to prevent rust
10. Remove and coat cowl panel with bedliner spray to prevent UV cracking
11. Wax exterior to prevent clearcoat fading
12. Lube front driveshaft and/or replace u-joint to prevent failure
13. Replace shifter boots - make your own with leather and superglue
14. Check idler bearings for wear and replace if necessary
15. Sand and recoat fender flares with bedliner.

 

If you are going to change the transmission oil, consider doing a double flush and fill using Castrol Transyd, it is a full synthetic used in Allison transmissions - $34/gal. Will never wear out, double flush and fill replaces 80% of fluid according to Allison engineer who used to frequent the DieselPlace forums - you can find more info on it there.

 

I like lists, the hose one sounds doable, I’m guessing replace with silicone hoses, is there a kit you can buy ? And a preffered brand I remember doing this work on the farm back in the day on old rover 90s, I’d rather invest in better stuff than do it twice later on, appreciate the help.

 

Silicone hoses are great if you can find them, but not required. The standard rubber hoses will usually go about 140k before giving up. Check Rockauto or ebay.

 

Thanks I had a look on amazon earlier they had a full system set for 300.00 plus usd , but was a hell of a lot of rubber

 

Couple good list there. I know idler/tensioner pulleys were mentioned...but they are probably the leading cause of a overheat event...they fail...take out the belt...overheat issue. Replace them. And, go with a quality thermostat, not the cheap crap...you end up toasting the motor because you tried to save $40.00...and you'll have a hard time looking at yourself in the mirror.

Leading cause of overheat event is crappy LR design thermostat. 2nd most common cause is a low coolant level due to leaking rubber or plastic component - replace all of it - hoses, tank, radiator, connectors. 3rd most common is leaking water pump.

I have overheated or had leaking heater hose, lower y, radiator, tank, and water pump.
