how to get oil coating out of cooling system on 1.9d

sssstew · Dec 13, 2006

Just got a 93 Golf 1.9d.

Any clues how to get a previous owners light coating of oil out of the cooling system? is there some strong flushing stuff you can get?

Aparently the oil cooler for the engine is leaking oil into the system so they have bypassed it, but im going to refit a new one but want to clear out the cooling system properly.

ive used dish washer fluid or tablets before and smells nice too

The issue here is finding something that doesn't wreck akk the seals in the cooling system.

If it was me, I'd give it 2 coolant changes. Whack some cheap yet safe coolant in for a week, then flush it out for good stuff. As the coolant gets warmer, it'll start to lift the grease off anyway.

we always use 1/4 box of persil/washing powder run it up till hot then drain fill with fresh water drain then fill with G12

Isn't it still soapy inside if you just rinse it once?

nah never don any car any harm with persil as it contains silicone. have used it over 100 times before always o.k.

Forte make a bio degreaser

if it can clean out the crap on a rover k series after a head gasket it'll do any car

goble - how much do you put in? and do you premix it?

flapper - thanks for the link, it looks lilke just the stuff

Just flush it with distilled water, and run it for a while, then refil and G12+

goble · Dec 15, 2006

spoon in 1/4 box into header tank then fill with water run up till hot let it cool down a bit the n drain run with frsh water then drain then fill with g12.
Remember cooling sysvingtems are hot and dangerous let it cool down before remo expansion bottle cap

I can get that Forte stuff cheap through work, Stew. If you're desperate though, MotorWorld in MK (www.motorserv.com) sell it.

sssstew · Dec 15, 2006

Fl@pper · Dec 15, 2006

Tom B is probably closer but I stock it too if you get really stuck

Persil

Hi......Just stumbled across this old post. I've got to replace the oil cooler on my Leon FR, so will need to flush the cooling system out. Can you tell me which type of Persil washing powder to use, is it bio, non bio or another type?

Cheers Dave

i use aerial actiilft clothes wash liquid sachets
designed for washing machines so ok on rubber hoses etc and dont foam as much as persil etc
use about 3 per flush do 2-3 flushes then clear with fresh water
add coolant
