The 525d E39 model had a M57D25 diesel engine, introduced in 2000 till 2003. This was a straight six and not a V configuration.
The water coolant on a BMW 525d is located in the radiator hoses, radiator and engine block. It is circulated via a pump which helps cool and maintain engine temperature.
The oil dipstick on a BMW 525d is located along the left side of the engine. It connects directly to the engine block and runs down into the oil pan for accurate results.
There is no BMW V6 engine.
...There is no BMW with a V6 engine. You may have confused V6 with Straight-Six.
The E39 525d doesn't have a timing belt. It is " chain driven ". The chain has a tensioner which is self-adjusting and should never need to be replaced. If you have any concerns about engine noises, performance or economy, you should spend £50 at your BMW Main agent for a full health check. You will find that the service is exceptionally good and well worth it for the quality of the car you are driving. I am a new BMW customer and I am very pleased with my purchase.
The BMW 5 series is basically a beefed up version of the BMW 3. The BMW 5 runs on a 6-cylinder V6 or V8, while the BMW 3 has an inline V6 engine. Performance models are even 'beefier' in terms of engine size and horsepower.
The 323i came with the M52 engine, which is a straight-six (not V format).
To my knowledge, no past or current BMW model has ever had a V6 engine. BMW has used V8's, V10's, and even V12's but no V6. However, BMW is thinking of putting a V6 into their new M3 model, since they are downsizing from a V8. They will more likely use a straight six with some sort of turbo I believe.
X5 does not equipped with V6 engine. It's I-6...
No, it is a straight 6 with a double overhead camshaft.
yes the BMW M3 has a V6 but it can have a V8
The 2011 Lincoln MKS has a V6 engine.
