Big overhaul approaching, any recommendations?
« on: May 22, 2021, 03:50:18 PM »

Soo... the car's 260 thousand kilometer service is closing in...

Things need to be addressed:
- Wiper motor mount on front is loose / busted on left side
- Clutch needs to be changed
- Valve clearance check
- Engine's chain inspection might be a good idea at this point
- Aux belt change
- Water pump change (still original)
- Air Condition Unit gas change / oiling
- Check exhaust, might be rotted because I think the car is a bit louder
- Fix throttle (aka take it out, refurbish), change the sensor also
- Buy internal decoration panels' plastic & metal clips, broke a few of them
- Finish DIY electrics inside the cab... Aka add relay & fuse box for mods
- repaint front wipers, 7 years later they need again a touch of paint
- buy front wiper nut's plastic cap, somebody stole one of them
- Change panoramic roof to new one?
- Change front windshield to new one, can't see through it when the sun is shining at low angle.
- Change CV joints? One of them is leaking from transmission a bit
- New transmission oil also?

wiper motor will need securing in order for it to work correctly

clutch - if it isnt slipping or smelling burnt, id keep it going

valve clearances will be worth doing

timing chain - if it isnt rattling, leave it alone

aux belt, if it hasnt been changed recently get it done.

water pump - again if it isnt leaking or noisy, leave it.

a/c - if its blowing cold dont bother

exhaust - might be worth looking it over

throttle - well worth doing

pan roof - sand and lacquer

try cleaning the windscreen thoroughly

if the CV boots are not split, leave them alone, its more likely to be the gearbox output shaft seal that will be weeping. you will loose a substantial amount of gear oil so you might as well replace it

- Clutch it has slipped multiple times and has generated itself back to working order, so I have been trying to kill it last 50tkm but seems like it wants to live. Kinda want to change it out of curiosity how it looks.
- I hear some "rattling" but might be just exhaust shield rattling with engine, yeah not going to bother opening the engine but kinda just visual check does it seem good with endoscope.
- Water pump is not leaking or noisy but judging the car is closing in 20 years of age and o-ring seals stay good for 10-15 years, so it should start leaking soon, so just doing preventive maintenance while I am around that area. Also coolant is pretty old, probably still fine.
- A/C is blowing somewhat cold but not as cold as it used to be when I bought it 7 years ago. Also I don't see any mention of anyone A/C maintenance before, so I would say for longevity of the A/C compressor it should be about time to change / refill gas with fresh batch of lubing oil.
- Windshield cleaning doesn't help, it has been 'sandblasted' by other cars during winters so you seriously cannot see outside during mornings or evenings, which is hazardous.
- One of the CV's is somewhat busted, it is either has been bent a little bit or u-joint has gone bad because it 'clongs' when I start driving but goes away after a few dozen meters.

Clutch - you should change it, after so many km, along with fork and bearing. Big difference after that!
Coolant - good idea to replace, even if  you think it's still fine. Will get rid of the interior rust.
A/C - good to insert new oil in the compressor. Long life.
Windshield - safety first!
Water pump - if it's not leaking or noisy, if you never had an issue with high water temperature, just make a visual check.
Gear box oil - "mine" was soooo dark and dense after 17 years and 190.000 km, like crude oil. So, give it a try. But first, check if you can unscrew "the in" screw! If that one is ok, go to "the out" screw and see if that one unscrews. If one is sealed in place and can't be unscrewed, leave it in peace.
Front wipers, electrics, decorations - do you thing!

I had a horrific experience with old coolant rotting just about everything that could rot, I say change it and if there's any rusty debris in the drained stuff, change the pump just to be safe. Then keep an eye on TVA and radiators (AC and main) for any leaks.

That said you're probably OK, but defo change the coolant 100%, I've felt the pain first hand of the damage it can do if left too long.
