Buying Used: Isuzu D-MAX RT Series – Quick Checklist

Buying Used: Isuzu D-MAX RT Series – Quick Checklist
4 min read

I've been driving my Isuzu D-MAX RT Series for a while, and I've learned a few things about buying used cars. I want to share some of my wisdom if you’re looking for isuzu d-max for sale in Melbourne. I'm going to give you some tips on checking that the car is in good condition before you buy it, so your drive won't turn into a nightmare!

Oil light stays on

If the oil light stays on, this is a sign that there's something wrong with your engine. There is a sensor in the engine that measures oil level. It tells you when it's time to add more and turn off when there's enough. If this sensor fails, it will stay on even when there is plenty of oil in your engine, so keep an eye out for this symptom if you notice it while driving around town or at home.

Another possibility is that something may be wrong with your oil pump—not enough lubrication means your car won't perform as well as it should, which could lead to other problems down the road (like reduced fuel efficiency). Buying isuzu d-max for sale in Melbourne, it's essential to diagnose whether or not this is happening, take some pictures of what's going on under your hood and bring them along so that a mechanic can check out everything before making any repairs or replacements.

Steering rack loose

The steering rack is a system that connects the steering wheel to the wheels for your Isuzu D-MAX. If you notice your steering wheel shaking when you drive, or if the car feels like it's pulling in one direction, then it could be a loose or worn-out part on your vehicle's steering rack. This can be dangerous as it can make it difficult to hold a straight line and makes handling more challenging.

Brake fluid is leaking from the brake lines.

Brake fluid needs to be topped up regularly, so check your owner's manual for advice on when this should be done. If you can't find anything in there, then we recommend you top it up every two years or 10000km (whichever comes first).

The brake fluid reservoir should also be checked for leaks at these times. If the line is damaged internally and leaking slightly, you may not see any wetness on the outside of either of your brake cylinders; however, if you look on top of them with a torch and shine it down into each cylinder you'll see some oil seeping out of both sides.

Check Brake Fluid Leaking Isuzu D-Max

If your brake warning light comes on when driving, this could mean that there is insufficient pad left before wear reaches dangerous levels; don't drive the car like this!

Misfiring engine, low power

If your used Isuzu D-max is misfiring, or it feels like it's got less power than you'd expect from a truck this size, then there could be a few reasons why.

  • Check the spark plugs
  • Check the fuel filter
  • Check the fuel pump


If you're looking to buy Isuzu d-max for sale in Melbourne, then we hope these tips have helped you to make a more informed decision. The best thing to do is always have an experienced mechanic inspect the vehicle first before making any changes or buying it outright. This way, there won't be any surprises down the road!
