GMC C6500 Topkick Customer Reviews

Universal Oxygen Sensor, Heated, 4-Wire, Sold Individually
Jun 26, 2020
Great parts, but ripped off on installation at BrakeMasters
Very happy with both the items you sent me, exactly what I ordered and fast delivery. I got both the "before" and "after" catalytic converter sensors, since the mechanic at BrakeMasters wasn't sure which one was causing the engine light. I told them to fix whichever it was - but the price the quoted me for a factory original sensor was $250.00 (!!) so I ordered these on-line from you, with their approval, and dropped them off. However, they later told my wife that neither unit would fit my 2012 Kia Sportage - some nonsense about "California Emission standards" (we live in Arizona and I bought the new car here). She didn't understand the details, and told them to get one that did fit and install it. When I picked up the car, the bill was $352.00!! And when they gave me the parts back, only the "after converter" unit had been opened - the other was still sealed in the packaging. Yet it was that one - the "before" unit - that they had replaced. They wrote on the Invoice that the parts I supplied didn't fit - now I'm going to have to return them to you, but not until I sort this out with BrakeMasters, where I've been a customer for almost 20 years. Wish me luck.

I'm a little confused!!!! I installed the o2 sensor and I still have the same problem. I might need the air injection pump to complete my mission.

The “check engine” lit up so I had to go to my mechanic. Apparently it was the oxygen sensor that needed to be replace. The initial quote was a bit pricey to I went online and came across this product. It worked fine and no issues so far.

It has comfortable seats and a colossal build that will surely be noticed on the road for people to make way. But even though it looks really big that it's not prone to any damage, you always have to check up on its parts to make sure that everything's still functioning. If not, better get these replaced with components that are fit to your truck, such as the GMC C6500 Topkick.

FAQs—GMC C6500 Topkick

The emergency brake light of my GMC C6500 Topkick won't turn off. What seems to be the problem here?

First, take a look at the emergency brakes and make sure that they are turned off. If they are switched off but the emergency brake light remains on, you need to check other parts to pinpoint the problem, so check the catalytic converter and find out if it is working correctly. You will need an electronic diagnostic machine to troubleshoot this component, so if you don't have one you might have to take your truck to a mechanic that can diagnose the problem. You should also check the circuitry as well and make sure that there are no blown fuses and that all switches are working. You might also have to adjust the switch to the pedal. If these don't help, check the brake fluid level. Sometimes, a dashboard brake light that stays on even when the emergency brake is off usually means your GMC C6500 Topkick is low on brake fluid. Open the reservoir cap and check if the fluid level reaches the mark, and top it off if needed.

My GMC C6500 Topkick was running fine when it suddenly shut down and refused to start. How can I fix this?

Before you try any tests, the first thing you must do is determine what type of no-start condition your GMC C6500 Topkick has. If you can hear the engine spin but doesn't catch and run on its own, then your truck has a crank/no-start condition. But if you don't hear the engine moving at all as you turn on the ignition, then it's a no-crank/no-start condition. If your truck neither cranks nor starts, the first thing you need to check is the battery, as it's the most common cause for this condition. A quick way to check the battery is to turn on the headlights. If they do come on nice and bright and not dim or dull, then the battery should be working fine. The next step would be to inspect the battery connections, as there might be a corrosion buildup between the battery terminal and the battery cable, which prevents your vehicle from starting. Meanwhile, if your truck's engine cranks but doesn't start, then your vehicle might be low on fuel or there is no spark delivered to the combustion chamber via the ignition system.

My GMC C6500 Topkick shakes so bad that it has damaged the A/C. Why is this happening, and how can I find the problem?

In order to narrow down to the cause, you must first determine if the vibration is in your truck's engine or the suspension. To find out, see if the vibration can be duplicated with your GMC C6500 Topkick sitting still. While in park or neutral and with the brake applied, increase the engine speed to the RPM that corresponds to the speed when the vibration occurs. If your cab starts vibrating, then the problem lies in the engine or torque converter.
