Default Oil in coolant

I just bought a 2000 3.0L V6 and am doing a tune up. I started flushing the coolant and noticed some oil in the coolant. Where do I even begin trying to track down the source of contamination?

The head gasket maybe?

Anyone ever heard of steel seal for a blown head gasket? I am gonna run a combustion test to see if emissions are running through the radiator....but have not been able to find good or bad about this product. Thanks

Never heard of that one..But auto parts store do have some that are usually $50+..Reviews are of course pretty mixed with both of them..but it might be worth a shot if you don't want to do a ton of work and don't expect the truck to last you too much longer.

Just make sure to follow the instructions very closely and read reviews online from others that have used the products. You can learn a lot from their success/mistakes.

Most products require that you flush the radiator/heater core/motor VERY good. And also remove the thermostat.

Ok....thanks Tommy. I am a little confused though, I just drained both the engine and tranny and neither are contaminated what-so-ever. The coolant is really dark in color and definately has a LITTLE bit of oil in it. There is only about 4 circles the size of quarters and the rim of the drain pan has the brown line. The guy at the parts store said my radiator is probably cracked. I am a little confused on how to procede. I am always sceptical about this liquid leak repair kits. DO you guys think I should just top everything off and keep a close eye on it?

Not sure why he would say your radiator is bad.. That would have nothing to do with oil in the coolant. (except for red tranny fluid).

If ther was only that much oil in it..Yea, I would probably just top everything off and keep an eye on it.

Mainly watch your oil level and make sure it doesn't rise. That's the worst..Dont want coolant getting in there...and if it's getting in the coolant, it's probably gotten in the oil too.

Do you have an AUTO?
Might be tranny fluid from the coolant lines attached to the radiator.
Does your temp go up while in traffic?
Continue to check your Motor oil ,making sure it is NOT a blown head gasket
It might just BE the radiator

Default Re: Oil in coolant

Since it is a new vehicle, I have been watching all of my guages very closely. I have put about 700 miles on it and the temp remains BELOW half on the gauge. I definately didnt notice any water in the engine oil. I just changed it today while engine was completely cold without seeing any water.

Off topic question....the heater cooler line on the radiator is on bottom driver side right? I am going to top off coolant tomorrow but wasnt sure how to fully flush the radiator. I just cleaned out overflow tank and drained/flushed radiator. JUst want to make sure I pul the right hose....thanks in advance!

-You did everything correct
-yes! Optional coolant lines are on drivers side
-If water temp stays normal, no water/milkshake found in oil,
And your oil level stays normal, just keep watch on radiator water level.
Sounds like it could be minor problem, but if it is a small crack in radiator,
it probably will get worse and eventually need to b replaced

Again, how could it be a crack in the radiator? I'm assuming the op can tell the difference between tranny fluid and engine oil. Are there enging oil cooler lines that go into the radiator on some 3.0s??

it is a manual tranny BTW.....and I can tell that it was engine oil, not tranny oil. Are one of those flush kits that can be purchased at auto stores worth it?

Then yea, you're radiator should have nothing to do with the problem.

It's probably just a small intake/head or possible timing cover leak(outside chance).. If it's just a real small amount..I woulnd't go tearing the motor apart over it. But don't be shocked if it gets worse and you notice the engine oil level rise as well. Mine was really overfilled - but looked clean. Sometimes you can get anti-freeze in it and it won't look very milk shakey. Just make sure the oil stays level. Just keep it in the back of your mind you might have to do the heads eventually.

I've honestly never used one of those kits - but I imagine they'd be fine to use. Just follow the directions. Mainly just important to hook a garden hose into the colling system to flush it all out.

Default Re: Oil in coolant

OK so I bought the flush fluid and ran it through....YUCK. It was brown still. So I topped it off with just water and reran the vehicle, flushed it, still disgusting. I am going to do one more water only flush and see how it looks before I top it off with 50/50. I honestly think some jackars put some tap water in there or something because there is definately some interior rusting going on. Although the vehicle has only been ran for about 30 minutes, I am pleased to say that the engine oil is remained consistant and I have not seen any signs of oil in any of the flushes I have done. God willing someone topped of the coolant with an oil soaked funnel or something (I know I am being optimistic!).

Anyone, I will keep you all posted. BTW, is it normal for the AC compressor to start and stop randomly with the vent and heat on full blast? It is kind of wierd to me because even the pully stops spinning when it shuts off. I am knew to Ford's and havent seen this before. Thanks!

The rust color is likely your water pump impeller being rusted out. Real common on these motors. Has the water pump ever been replaced?

Dont tell me that Tommy! I but it used with limited maintenance history. I didnt see water pump in the history anyway.....

Is this something I can just wait on? I have always replaced my water pumps onthe recommended service interval. I have heard of them going up due to rust though. Like I said, the coolant temp has remained below half way on the gauge. Is this something I can wait till it gets worse on? I have flushed it out pretty darn good so....

I would really hate to have to replace the damn water pump right after I flushed the shit out of my radiator
