Parts Owning a BMW has always been a dream for many and a reality for a few. Let's face it; BMW vehicles are not affordable and not too many people really has all the cash to buy such vehicles. The good new is that there have always been a lower priced option for each BMW vehicle model; and for the sporty BMW 3 Series, this is the BMW 325i. But does the BMW 325i have all the characteristics one would expect from a BMW 3 Series vehicle?
The BMW 3 Series has been around since 1975 but the BMW 325i designation appeared not until 1983 in Europe and 1987 in North America. Upon introduction, it was a compact sedan and was among the smallest of cars in BMW's line-up of vehicles. And following BMW's tradition of naming cars, the BMW 325i was equipped with a 2.5-liter engine, specifically a 2.5-liter 6-cylinder engine that produces 168 horsepower.
Today, the BMW 325i is still a compact and sporty sedan, but it is no longer the same small sedan that the world knew of in 1987. The new 325i definitely no longer share the appearance of the 1987 BMW 325i, and neither does the new car share the parts of the old one. The new BMW 325i is no longer equipped with a 2.5-liter engine. Instead, it is now equipped with a 3.0-liter 6-cylinder engine that outputs 215 horsepower and 185 lb-ft of torque. And no longer is the car among the smallest of cars in BMW's extensive line-up, as that place has already been taken by the BMW 1 Series vehicle models.
So, does the BMW 325i have what people would expect from a BMW 3 Series? Definitely yes, especially with the new BMW 325i parts and features it is geared up with for the 2005 and 2006 model year. Aside from its powerful 215 hp engine that features Valvetronic technology, the new 325i is also equipped with a 5-link/5-beam rear suspension, 6-speed STEPTRONIC transmission, xenon adaptive headlights, dynamic stability control (DSC) system, and a Bluetooth interface for the BMW Assist, BMW's on-road assistance program. These are all aside from those parts that many people have already come to love about the BMW 325i in the past.
I noticed a significant loss of coolant in my BMW 325i. The leak usually happens when the car is sitting idle at the garage or parking. I tried filling the coolant and it would leak after I drove the 325i. Any idea what might be the problem?
One of the most common problems reported on the BMW 325i is coolant loss which has been diagnosed as due to leak in the expansion tank. When not repaired immediately, this could result to engine overheating. It is advisable that you check your entire cooling system once a component or two starts failing. Your expansion tank may not be the only problem. Make sure to check the coolant level in the expansion tank every time the gas tank is being filled; this way, you'd be able to monitor any unusual coolant loss immediately. If you noticed that the low coolant sensor is not working, it could be time to replace the expansion tank.
Driving my BMW 325i when suddenly the Check Engine Light came on; it went on and off for a few seconds. When the car was cool, it disappeared. Is this related to any cooling system problem?
If your BMW 325i's engine is overheating at the same time the CEL came on, then you might be having a problem with your cooling system - specifically the thermostat. It's not actually very surprising for the thermostat to start failing after racking up miles since it's the component in your engine bay that has to work harder. Since overheating can cause severe engine damage, you don't want to take this problem for granted. Replace your thermostat right away and do a complete check of the entire cooling system to avoid further engine troubles.
I had to replace the radiator in my BMW 325i due to leaking. Do I have to expect replacement or repair in the near future again?
It is not unusual for a radiator to develop leaks and this will happen to your BMW 325i after about 100,000 miles depending on wear and tear, whether you like it or not. Leaks in radiators develop around the upper or loser hose connections because of vibration. If you have aluminum radiators with plastic end tanks, expect leaks to occur at the seams where the core is connected to the end tanks. Internal corrosion can also cause leaks so make sure to remove old coolant periodically.
In case of leaking radiators, you can choose to repair it yourself or have a mechanic go at it - depending on the severity of the case. If the core of the radiator is severely corroded or damaged, the only option you have is to replace it with a new radiator. Make sure to check other cooling system component for additional leaks.
I got a problem with my BMW 325i recently. When I drive it at high speeds, say above 75MPH, I can feel vibrations. What should I do?
If your BMW 325i is vibrating with the steering wheel shaking, the problem is with the front wheels. If you can feel vibrations through the seats, then the problem are the rear wheels. What you're experiencing could be due to tires that are out of balance. You can have the car serviced by a mechanic. They will balance the tires using computerized wheel balancer - the device will check the imbalance before weights are added to correct the problem. Wheel alignment is another solution to a vibrating vehicle.
From Fast to Furious: The History of BMW 325i
With the shock of the oil embargo finally wearing off, more and more car enthusiasts considered the idea of forgoing fuel economy for better performance. The answer to this growing demand came in the form of the BMW 325i. First introduced in 1987, the 325i was derived as a modification to the already popular 2nd generation BMW 3 series. Although the 325i looked similar to the original 2nd gen E30, the difference lies under its hood. The new BMW 325i abandoned the concept of a reduced-rev/high-fuel-mileage "eta" engine and was replaced with a more powerful bay.
1987: A BMW sports car like no other
The BMW 325i was more popularly coined as the first genuinely sporting BMW since the 200tii. This was all because of the modified eta engine that was commonly seen as definitive of the same M20 family. However, the slight differences between the two BMW models were the reasons why the 325i became one of the most powerful 3 series model during its debut. Aside from the addition of a fuel injection system, the 325i engine was also defined by a shorter stroke—down to 6mm stroke from the eta engine at 75mm. This allowed the rev range to open up an additional 500 rpm that boosted power output to 168 hp. With a test drive resulting in 60 mph in just 7.4 seconds, the introduction of the BMW 325i was a success and it produced a considerable following in the small sport sedan market.
1988: Power in a convertible and all-wheel drive
The popularity of the BMW325i’s power prompted the release of other models that had the same exhibited performance in different car types. Following the introduction of the sedan, BMW decided to adapt the 325i engine into both convertible and all-wheel drive models. The 325iC convertible was the first pure convertible offered in the 3 series and was introduced roughly the same year as the original 325i. The following year BMW debut the all-wheel drive 325iX, which was the 325i's highly touted luxury sports model that gained a following amongst younger drivers.
1992 - 1993: A more powerful engine for the BMW 325i
If the 168 hp featured in the 325i engine wasn't enough, BMW decided to up the notch during the early 90s with another modification in its engine bay. The new DOHC 24-valve aluminum head found under its hood increased output to a new high of 189 hp. The previous record of 7.4 seconds for 60 mph was now replaced with 6.9 seconds. The new BMW 325i was now running fast that ever and even covered a quarter-mile in 15.3 seconds at 91 mph.
1994: The BMW 325i's style revolution
While other generations of the BMW 325i featured upgrades done under its hood, the 1994 model saw changes in its exterior. The sedan coupe now had a more steeply laidback front windshield and rear window. Together with these changes and its A-pillar back, the 325i coupe looked liked a completely different car. The typical sedan exterior that was adapted to the 1994 model made the BMW 325i more comforting and relaxed. However, its new image similar to a family sedan brought mixed views to most critics. While some believed that the new image made the car more approachable to buyers, critics cited that BMW could have been more radical with the coupe.
1996-2006: A popular performing engine that lasted 10 years
Towards the end of the 90s, the 2.5-liter engine in both the 325i and 325iS was upgraded to a 2.8-liter inline-6. However, this engine change also prompted to the rechristening of the BMW 325i to 328i. It was later rereleased with a more robust 3.0 liter, 215-horsepower engine, and a Steptronic transmission. The same specifications lasted until its last year of manufacturing in 2006.
