MY COOLANT IS MIXING WITH MY MOTOR OIL!

I have a 2007 Rav4 Limited inline 4... less than 45k miles on it.

Just recently i've noticed that my fan has been on a high rpm, check my coolant reserve, and everything seemed fine and normal.

I did get into a two minor front end accidents, but no damages just a couple of scratches on the bumper it happened about half a year to a year ago.

This past Tuesday March 29th, my brother took my car in the morning and said the temp gauge red lined as he was driving to school. He called Toyota and said to just fill it up with water as a temp fix until he can get to a store to buy some more coolant. He brought it into his mechanic and found no leaks or anything. But after adding more coolant it just seems to disappear the next morning. There is no puddle underneath my car or anything, until last night when i went to go check under the hood, i found my coolant reserve to filled with a milky chocolate brown solution. Check my motor oil and found the same solution in that.

Any ideas suggestions? My mechanic told me this is the worst condition it can be... and I'm looking at around a thousand if its the head gasket.:wa ll:wa ll

You should still have warranty on the vehicle. Call up the dealer where you bought the vehicle and tell them of your problem. Usually the warranty is 5 yrs/50k mi...whichever comes first. Good Luck!!

I had experience with 87' Nissan Maxima; 96' Camry; 96' Acura 2.5 TL. I try to do any repairs at home with whatever skills/knowledges I so far have. Things I don't know, I ask my uncle (Honda Master Mech.)

Yes, Justin, this should be covered under the 60 month/60,000 mile powertrain warranty. Unless they try to blame it on those 2 minor front-end accidents. Which I would conveniently forget to mention.

Pricey, Head gasket, you might have your head milled, it was from heat. add on to that the labor. Toyota or the person or dealer that you bought it from HAS to pay for it.

Time for a new headgasket. If you overheat it you might warp the aluminum head too.

I had this happen in my 2002 Subaru Impreza and in a 1992 Pontiac Grand Am. Both times it was diagnosed as a blown head gasket. This is not something to let slide.

In my Grand Am I ownly learned of the problem when I was flagged down by someone on the highway saing my car was on fire. It turened out sparkes were flying out the tailpiupe. When I looked underneath the car I saw the pipe up where it meets with the catalytic converter was glowing red.

Eventually the blown head gasket was diagnosed. I was told it would be two grand to fix it. I sold it for parts.

As for the Subaru, it overheated one month after I had the timing belt, water pump and thermostat replaced because the water pump had a leak and caused the car to overheat. My mechanic pressure tested the engine and said there were no external leaks. They said the coolant was being used up somewhere in the engine. They surmised it was probably due to a blown head gasket.

Having known what happened to my Grand Am I traded the Subaru in for my Rav 4 while it still had value. I knew it would have only been a matter of time until it died.

So if your Rav 4 is still under warranty get it into the Toyota dealer as soon as you can before it becomes terminal.

Since you have mixing oil and water, I hope there is no damage to the bearings. I'd be skeptical of just a head gasket repair from Toyota.
