    no1 is trying to clean the coilover.

    i want to be able to unseize the huge height adjuster thats solid as fuck on the column.

    what type of oil to soak it in?, also how expensive is it? as to soak 3 coilovers up to the height adjuster you probs need 5 litres minimum?

    coke is cheap

    Get a long tube type container to soak them in, you won't need as much fluid and you can leave the end you don't want submerged sticking out the top.

    Use real coke, and if you can heat it. i mean really heat it till it boils for as lonmg as you can
    it will unseize pretty much anything.
    this coming from a person who has about 50 cans of plusgas in the cupboard and prefers to use coke !

    Ok, short update...

    Cheap coke for about 5 hours, after boiling water directly on the adjuster ring, after leverage + c-spanner = no success.... :cry: It seemed promising at the beginnig, as a lot of gunk was floating on the water after an hour.
    It really seems like I have to use agressive methods to make it work.. I'll try diesel next time, but still afraid of melting down the protective zinc coating. If that doesn't work, say hello to battery acid. :(

    Edit: repeated the procedure using hammer and flatheaded screwdriver, but still seized..

    a mate of mine had this on his tein coilovers. he had to use a junior hacksaw on the locking collars and before cutting down through the threads smack a small chisel in the slot you made to crack the collar. its last resort but easyer to sourse new lock rings and much better than wrecking your coilovers completley.

    Malt vinegar, leave them in there for 3 or 4 days

    Plusgas the shit out of them. If not, then stick them In a bucket of diesel like you've been told.

    When I did a set of coilovers last that were stuck I froze them overnight then dumped boiling water over the rings that was after soaking them in coke for a day. This method does take 2 days with your car in the air tho. And when freezing them you have to leave them in your freezer for about 12 hours to get them proper frozen.

    Thing is, i its not the lock rings that are seized, they are easy to loosen.

    its the height adjuster.

    i can get enough force on the adjuster to spin the entire shaft through all 3 lock rings that are next to eacother.

    but cannot loosen the adjuster.

    gonna try coke next week.

    coke does not work at all on a coilover height adjuster

    soaked for 12 hours, no change, had to take it to garage D, it took them an hour to unseize 1 coilover, it was seriously seized.

    Blow torch, Hammer, 2 C spanners with breaker bars, back and forth back and forth, back and forth, in a vice, every time getting that 0.1mm further with each turn, until a complete turn took place.

    im a persistent guy, but there was no-way i was doing this without a blowtorch and a breaker bar on the C spanner.

    Mine is unseized aswell. Took it to a suspension place, and they unseized it for me. They used heat aswell. They did it for me for 10 pounds. :) Gave it to the shop, they gave them back 3 hours later. So this was my method. :D
