Thread: oil in coolant.......

just think aloud here.

How would metho effect the seals?

dunno if metho would be strong enough to dissolve the sludge........

but it shouldnt affect the seals.......

thats why i was thinking kero.......plus its sort of oil based......

kero would leave an oily residue i would have thought...

i think i would be trying a strongish detergent with low foaming properties...

interesting problem...... be interested to hear from a pro what the fix is...

interesting problem......but a massive headache........

the kero is a lot easier to wash out than the mud thats in there now......
its got the consistency of one shot grease......

and it sticks pretty well.......i need to dissolve it first to flush it out......
then i can run soapy water through as a wash......then rinse that out......


i am stuck.......its a real pain.......for something so simple......

i need to know of any methods that may clean it out........
such as fill the cooling system with kero and run for a while.....?
dont want to use caustic soda as that will eat away at the internals of everything.....
including all the rubber........



tried spraying a tin of degreaser in the top hose and then hitting it with the gerni but its not good enough.......

it has the consistency of grease......i need to dissolve some how so i can flush it out.......

You could try this stuff. It is water soluble, dissolves grease and oil and is enviromentaly friendly. Shouldn't damage your engines metal as it is non corrosive.
Probably tip a litre into your radiator, run it and then flush the crap out. Magic stuff for degreasing engines too.

CT14 Gutsy Degreaser
Concentrated, water soluble, biodegradable,
hydrocarbon-free, non-toxic, non-flammable. Great for engines, driveways, lube bays & transmissions
1Ltr makes up to 20 Ltr .
CT14-1L
CT14-5L
CT14-20L

Or the Truck Wash, it removes grime, you can even wash greasy overalls in it.

how'd the oil get in in the first place?

See if you can get some soluable oil and pour a fair amount of it into your raditator about !-2 Lts, then pull the top hose off and place a strainer ( old stocking ) over the out let and replace the hose, bring the engine up to normal opperating temp and let it run for several minutes. the soluable oil will break down the sludge (engine oil ) and the stocking will catch a lot of it, keep an eye on the temp gauge, Drain the cooling system and repeat if required them flush the entire system with I think its called wynn' s raditator flush useing a bit of clean stocking again any gunk thats left in it.
I have heard that diesel fuel will do the same but never seen it done with it
But I think you may have other problems engine oil is mixing inthe cooling system what colour is the oil in the sump?

Best of luck Hodgo

that ct-14 sounds like an idea.....




split auto cooler in the radiator.....even had a bit of water in the tranny.....
but managed to flush most of that out.........

need to clean out the cooling system now and get it running......
then flush the auto again.......hopefully its not damaged......
