I would not assume that you have a problem. Most of the components in the cooling systems are non ferrous. From your description it does not match oil contamination. Can you post a photo of the coolant? I've seen cheap coolant that looks rust coloured from new which developed into rust coloured sludge. How long has it been since the last coolant change? ...

Air is getting into the cooling system to cause rust. The most likely place is the radiator cap ( not the reservoir cap ). The radiator should be "sealed" , the only exchange should be into and out of the reservoir which acts as an air lock to keep air out.

From your description it doesn't seem like oil. As for why it continues to look brown, you probably haven't flushed it enough times. When I had an oil-in-coolant condition on one of my vehicles, it took the mechanics at the dealership 12 flushes for the coolant to come out clear. And this was after having replaced most of the cooling system's hardware (...

Oil or coolant leak could be just through micro-crack which could be slow and not so easy to noticeable process. When you check coolant reservoir you should notice oil and thick fluid on top of (reservoir). Also if there would be leakage in vice-versa system then fluid levels should increase either oil level or coolant level. My guess is that you had some ...

As jwh20 stated in comments, the ambient air temp sensor is for the outside and has absolutely nothing to do with the engine coolant. From your description, you've not indicated anything which shows the vehicle is overheating. Your description leads me to believe you are worrying about something which doesn't exist. The vehicle is most likely running as ...

Just to illustrate how subjective this question is - about 10 years ago, I bought a 1939 Farmall tractor from the son of the original purchaser. The family had actively used the tractor on a small farm from new until a few years before I bought it, it had unknown thousands of hours on it. It clearly had a (minor) headgasket leak. The son (who was in his ...

The long term effect is that the leak will etch a groove in both your engine block and heads. There may be a groove already there, but it could still be within "surface flatness" standards. Causing structural damage to your block and heads is a costly mistake. The "flatness" standards for each gasket mounting surface should be outlined in the shop manual ...

It's impossible to say how long a relatively minor head gasket failure will stay that way, it depends on the placement and nature of the failure, as well as other factors. It will certainly get worse, either all at once or gradually. Being gentle on the power will certainly help. If it's gradual you can live with it, but all the while you're getting oil in ...

It may fail at any time. Some have been known to go on for years, others next day or week. If you value the vehicle then get it fixed, if not then when it fails dump it.

Radiator flush isn't anything magic. It is just a corrosive liquid that attacks everything in contact with it, to greater or lesser extent. You hope it dissolves the blockage before it makes a mess of anything critical like the cooling passages in the cylinder block or the inside of your water pump, or it dissolves a hole in the radiator itself. (Old ...
