How to Replace an Old Oil Cooler Seal
Your car’s oil cooler helps maintain the appropriate temperature for your engine, thus, keeping it in tip-top shape. But once the oil cooler leaks, it can hazard the entire engine, and can cause harm to you and your passengers. Oil leaks are often caused by an old oil cooler seal (or o-ring). When it is time to replace your oil cooler seal, follow these easy steps.
Difficulty level: Moderate
- For your safety, wear personal protective equipment (PPE) such as latex gloves and safety glasses before working on your vehicle.
Tools that you’ll need:
- Jack and jack stands
- Replacement oil cooler seal
- Axle grease
- Oil catch
- Oil rags
Step 1: Using a jack, lift the front of your car, and support it with jack stands. Lay underneath the raised portion of your vehicle. Lying down, locate the oil filter. It looks like a black cylinder, and it is where the oil cooler is screwed onto. Using a wrench, detach the oil filter. Watch out for oil leaks; use an oil catch or rags to clean up the spills.
Step 2: With the oil filter removed, check if there is a stud with a nut in the middle. Unscrew the nut carefully, and if it won’t nudge, you may use a breaker bar to do so.
Step 3: Using a screwdriver, you may now remove the oil cooler sealant, or by simple pushing it using your finger. It is a thin, ring-like object in the oil cooler. Put a bit of axle grease on the new seal first to lubricate it. Change it with your new oil cooler seal, and make sure it perfectly fits.
Step 4: Reassemble the parts. Re-attach the oil filter, and you’re done.
Removing the oil filter may be a bit hard for a first-time DIYer. You may use a rag to hold it, and carefully detach it. Replacing the seal will not take you more than 15 minutes. With your new oil cooler seal, your engine is safe from oil leaks, and you are back to smooth driving.
