[Maintaining a car every day] What is the experience of repairing a car that is older than you?
Hello everyone, this is a column focusing on car repair and maintenance. There are car mysteries you don’t know, and it will teach you how to avoid the big pits on the road of car ownership. I believe that not only you but also many people have a certain sense of obscurity about the car aftermarket, which will help you uncover the unknown stories of car repair and maintenance.
Forgive me for not putting a panoramic picture of the car. I like this angle very much. Let’s guess what kind of car this car really is.
Compared to seeing the whitewashed tire pattern and the whole front suspension, I can already feel that this car must not be the product of this century. Friends who are familiar with American cars can basically guess that this is an American car even through the wheels. The yellow appearance requirement of the turn signal has always been a mandatory law in the United States. Friends who hang out in Tianjin Port all the year round must have a good understanding of this requirement.

Since it is an American model, it is the engine that has to be mentioned. When I opened the cabin cover, I was shocked by the huge air filter. I think the condition of this Cadillac Fredwood made in 1993 can be described as excellent, after all, it is almost 25 years old.
Air-conditioning pumps and generators are placed on the left and right sides of the engine, this design can no longer be seen, air-conditioning pumps are basically hidden at the bottom. The white board on the side of the air-conditioning pump is the bracket of the air-conditioning pump, yes, it is that big. To describe it in a word, basically everything in that era was stupid.
The consistent style of American models is that the winding of the driving belt must be marked on the frame of the water tank. This tradition has not been changed, and you can refer to the recent generation of Buick GL8 for details. The engine displacement is also marked at the intake port of the intake manifold.
American style is shown everywhere, and the front bumper is very stout. I feel harder than some modified bumpers now, and maybe I didn’t think about the safety of pedestrians at all in those days.
The Cadillac logo of 1993 is a little different from what it is now.
It is said that Fredwood is showing its luxury everywhere and its configuration is quite rich. I always thought that children’s locks were the product of more than ten years ago, but I didn’t expect to have them in the last century.
The main driver’s door is integrated with a lot of control buttons, most of which are decorated with chrome-plated material.
A knob for adjusting the brightness of a light.
Large and comfortable seats, almost no wrapping. I’m really afraid that a careless driver will slip out from the top of the seat. I think the leather seat is one of the weirdest, hot buttocks in summer and frozen buttocks in winter.
The holes in the seat fit the age of the Fredwood, and the seat has all the functions of heating and memory. Seeing this, it looks like this Fredwood can’t even be luxurious.
The interior of the dark style.
Since it is to repair the engine oil leakage, there is no doubt that it is most reasonable to remove the engine and repair it. Although the displacement of the 5.7 liter engine is large enough, the volume of the engine itself is not large. It’s even a little small.
The throttle design is very special, maybe I have very little contact with the models of that era, which makes me very uncomfortable.
The timing chain of the valve system uses an engine with a central camshaft. The timing chain can be very short, and what’s even weirder is that I haven’t seen any tightening system at all.
The engine of the valve cover and intake port that was removed did not use a double valve at that time. So this engine has a single valve, and the intake basically limits the power. So the maximum power of this engine is only 280 horsepower and the torque is only 330 Nm.
The car is going to be carefully repaired, so the first episode is shared here, and the next meeting will talk about the maintenance process of the engine in detail.
