I would be more concerned about whether engine oil is actually finding its way into the radiator from the engine. If it is, this would be indicative of a compromised head gasket, warped cylinder head, or damaged oil cooler (if the car uses radiator coolant for cooling the oil). The first two items are not trivial to replace or fix. The third one isn't far ...

The seller should not be selling the vehicle with oil in the cooling system. That supposed "quick fix" should have been rectified at the earliest opportunity. Have him flush the cooling system and put another few tens of kilometers on the odometer before you even consider such a vehicle. If the seller is topping off the radiator with oil instead of water, ...

An engine is a very large thermal mass. When the engine is cold it takes time to warm up. If you only run the engine for 15 to 30 seconds from cold there should be no problem. Running the engine any longer than that may cause the engine to overheat.

Yes, it's possible some of the seals designed to withstand water and glycol could get damaged I am thinking you are creating a fictitious scenario here, so I'll roll with it. If you filled your radiator with oil and started your car and let it run for awhile I would be most concerned with damage to seals that were designed to withstand water and glycol. ...

It can absolutely be started without a radiator. You will not cause any damage as long as the engine does not overheat. If you don't run it long enough for the engine to get too hot, it's not an issue. To give you an example of how it could be beneficial: I used to own a 94 Camaro Z28. The engine in it was a Gen-II LT1 350. This engine has what's called an ...

Strange - engine coolant is antifreeze diluted with water. So the seller is claiming he had oil but not water? I would not buy that car. For the seller, a coolant system flush would in order, both forwards and reverse, and then refill with antifreeze and clean water. If engine oil still appears in the coolant water then the oil is moving from the oil ...

There are two answers to this question: Theoretically, radiators are completely optional on engines. Air cooled engines have existed for a very long time. The function of the radiator on these engines is replaced by cooling fins to extract the heat and release it into the air, and they also have oil coolers as well to carry out the heat. However, if your ...

Only based on your question. The answer is yes. You can run an engine without radiator. You just need to find an alternative way of keeping it coolor you will end breaking it. It's not immediate, but once the engine warms too much it will break. There are many engines that were develop specifically with this purpose in mind and only use the air flow to keep ...

As oil has a higher viscosity than water, I think it could damage the water pump because it would put more stress on it. Also, the oil would flow slower than water and this could lead to overheating of the engine.

Have into account two factors: oil viscosity may be much or very much higher than the antifreeze fluid (glicol-polipropylene derivates) normally used: the radiator grille has capilare-thickness tubes and an hydraulic circuit (pump, filter, reservoir...) prepared for much less viscosity. Furthermore, the oil will becoming more and more viscose while the ...

I consider it quite more likely that it was the engine that had been putting oil into the coolant. Of course, it may also be that the seller poured some obvious additional oil on top in order to mask the defective motor seal, a very expensive defect to fix.

An MOT in the UK will test these things. For more details on how they test your car, see here. Your car will either get a pass or a fail for each one. If get a fail in any one of the categories, that will constitute a fail overall. They are not required to do any work on the car, not even adjust the tire pressure or replace a bulb. Some might be kind to ...
