Can anybody explain to me what is the best way to change all fluids in my C4, Lt1?
Where are the drain plugs?
Also, where are the knock sensors in the block?
Wow, a Vette in Croatia! I saw C4 coupe in Ljubljana five years ago. Your's maybe?
The plugs are all under the car, pretty easy to find. You have to remove the rear differental cover to get that fluid out or suck it out the fill hole. No idea where the knock sensors are. Do you have a factory manual?
The knock sensors are located midway on each side of the block just above the pan. They are covered by heat shields which are held on by 3 small nuts.
Good luck
