Quick update:
Decided to get an M14x1.5 tap and die from Amazon for £9.99. The initial thought was due to the brake carrier bolts, and their general state, but weighed up the pros and cons of just getting new bolts.
I then realised that the wheel bolts are the same, and they're in even worse state, so I felt cleaning them up with this will be worth it.
Also this arrived earlier:
The replacement hose to that additional cooler. Second hand one from eBay for £15.96 which I think compares similarly to an actual new one from lllparts etc.
Guess I got impatient and didn't want to wait a week or the extra tenner or so for delivery unless I'm buying a bunch of stuff.
It's the correct part I believe:
So 5Q0 121 051 L as per https://www.lllparts.co.uk/product/5Q0121051L/skoda-coolant-hose-5q0121051l (the 5Q0 121 051 without the L suffix is more expensive).
It's interestingly dated circa 2013, so it'll be the oldest part of the car! It came from an Audi Q2 according to eBay, so surely a premium part, lol.
Anyway, the 7mm ratchet spanner to take off the clamps and replace with the new one:
All tightened up to 5Nm. Then just topped up the coolant tank slightly:
The old one with its rip:
Chalk it down to my aggressive use of the pliers to free it from that radiator.
Started to rain so tidied up, grabbed some bolts and ran back to the house.
So this is an example of the brake bracket bolt:
Just lots of aluminium corrosion where it passes through the hub and the rusty end which is where it's bolted and exposed to the elements.
So got the die, put some 3-in-1 oil on its cutting thread and all on the bolt, and just winded it through:
Any bit tight just got the ratchet spanner and for these bolts, a 21mm socket to aid getting the bolt through. It'll then usually go through easier and can then be done by hand. It's normally a case of winding a turn then back half a turn, but that's more applicable to cutting new threads.
Once wound all the way in, just reverse it out:
Quick wipe and it's better than it was.
Repeated for the rest and started on the wheel bolts:
The wheel bolts were a mixture of ok and horrid, some with mountains of grease built up and some without.
This is after half of the wheel bolts:
So I guess some brake cleaner would probably finish these off ready for reuse.
Oh, and the other 10 bolts I guess.
I'll check up on the coolant level later and once I top it off and it stays relatively stable, then we're really getting there.
Still need to angle tighten the strut bolt to the hub, then reassemble the front brakes.
Once those are done, then technically there's nothing stopping the car from being fired up!
