Radiator and Brake Replacement: A Simple DIY Guide

Radiator and brake replacement can sound intimidating. But with the right approach, you can do it yourself. In this post, I’ll show you how I handled both repairs step-by-step. Plus, I’ll share tips to avoid future problems. Let’s dive in!
Radiator and Brake Replacement: My Experience
Sometimes, I wish there were 25 hours in a day instead of 24. That extra hour would help me update my blog and reply to all the comments and emails. For now, I want to apologize if I’m slow responding.
Previously, I shared about a rusty stain near my radiator. Unfortunately, my suspicion was right — the radiator was leaking. I thought about replacing it with a full aluminum one. However, most available models fit manual transmissions, not mine. So, I asked my dad (my “personal runner”) to find a replacement in Ipoh. Meanwhile, I patched the leak temporarily with epoxy.

Luckily, my dad found a used aluminum radiator for only RM150. The installation was straightforward. First, I removed all the hoses connected to the radiator. Then, I drained the water by taking off the stopper and two screws on top. After installing the new radiator, I realized I should also replace the old hoses with silicone ones soon. They will likely wear out quickly.
Before removing the radiator, I inspected the engine bay. I noticed the plastic part on top of the radiator was hitting the front engine bay bar. This contact caused the leak. So, if you own a similar car, check for this issue before it worsens.
Radiator and Brake Replacement: Brake Pads
Next, let’s talk about brake pads. I replaced mine during my L5 engine conversion. After four years, they wore badly. The right pad wore down to the metal and started making noise when I pressed the brake pedal. Fortunately, the brake discs were still in good shape despite the worn pads.
Replacing the brake pads is not difficult. You’ll need a spanner, screwdriver, and brake piston reset tool. Here’s the quick process:
- Remove the wheel.
- Unscrew one bolt to release the worn brake pads.
- Take out the old pads and slot in the new ones.
- Reset the brake piston to its original position before tightening the bolt.
- Put everything back, and you’re done!
Doing this yourself can save RM10 to RM30 and give you a sense of accomplishment. If you want, I have a few spare brake pads for sale at reasonable prices—just reach out.
