after head replacement....

[the_skin_eater]

Ok, I had a craked head, got it fixed, flushed the system several times and discovered it was still leaking oil. Got it fixed, and today I reflushed the system, which had oil in it. After driving for 5 mins. theres oil in the tank again. So, is there just a lot of oil in the radiator? I bought a new coolant tank so that was clean, and got new radiator hoses too....Should I just flush again? Im realllly tired of having to do this, and Im on my 3 gallon of coolant.

Just wondering whats up.

Did you get all new hoses? I replaced 6...and there's still the small one that connects to the coolant tank that I have to replace. My mechanic flushed my radiator & heater core for an hour to get all the junk out. And even still, there was a (very very small) amount of oil showing up in my tank...but only enough to "run a ring around" the top of the coolant.

Try not to laugh too hard, it works.

Re-fill with clean water and some dishwasher detergent. Run the car until it's warm and then let it cool and drain. Repeat the process until the drained water/detergent is clear. Finally, replace the thermostat and re-fill with coolant/water mix.

It does a great job of eliminating oily sludge in the cooling system.

I was wondering what I could use to help with the oil....I'll try it...

And no, I didnt replace the lil ones. I mainly wanna get rid of the bulk of the oil, a small amount would be satisfactory right now.
thanx.

That's automatic dishwasher detergent you want to use..................

Only.

I had experiences with these Saturn cracking heads and the only thing that works is dishwashing liquid.


1) You got to take out the thermostat.

2) Put in 2 oz dish liquid and fill up with water.

3) Drive for 5 minutes until warm.

4) Dump the water and then flush with a garden hose by purring the water into the pressure container and letting out by the radiator upper hose (detach that) and engine outlet. Run the water until clear.

Repeat 5 times.

Put the thermostat back. Fill with antifreeze.

Since the thermostat is in its special housing...can the actual thermostat come out?

[the_skin_eater]

When you say pressure tank, you mean the coolant resevoir?
And, after taking out the thermostat the detergent and water just goes into the coolant tank right.
I will try to do all this tomarrow, let ya know how it works...

Oh yea, any ol detergent will work?
