Direct Fit Horn - Low Tone
Sep 09, 2019
Not exactly a “direct fit” horn
It is not what I would call a “direct fit”. The bracket is not like the original. The original has a metal tab that inserts into the fender well. This does not.

GMC Sierra 2500 HD Guides

Take Note of the Usual Problems of the GMC Sierra 2500 HD

The GMC Sierra 2500 HD may be a heavy-duty truck, but that doesn't excuse it from having problems that give drivers a hard time. Here are some of the common problems that truck owners should know so they won't be surprised should they experience these.

Muffler

One of the common problems this GMC truck experiences is the rattling or popping noise that comes from right under the vehicle. With such case, the driver may automatically think that his muffler may have already blown, but a careful inspection would show that the noise actually comes from the muffler heat shield. This problem begins when the muffler heat shield becomes loose. So if you step on the gas and accelerate, the heat shield will create more noise. Making sure that it's properly attached to the muffler should easily solve this problem. In fact, General Motors offers a kit to properly correct it.

Hydro-boost relief valve

Owners of the Sierra 2500 HD may have a hard time stopping the truck, especially if they're driving at high speeds. This can be attributed to the malfunctioning hydro-boost relief valve, which may not have been compatible with the model when they rolled off the factory. As a result, the seal of the valve cracks. And if the hydro-boost system doesn't perform its function properly, drivers will have troubles on the road and get themselves in an accident. That's why in 2004, the National Highway Traffic Safety Administration ordered General Motors to recall the 2003 and 2004 models to have their faulty hydro-boost relief valve replaced. This recall potentially affects about 69,000 units.

Instrument panel cluster

Many 2500 HD truck drivers have been complaining about the faulty indicators, gauges, and meters on their dashboard. Reports show that speedometers have been working erratically and fail to show the real speed they're moving at. Also, the fuel gauge shows a full tank, but then the needle would go halfway down. To make matters worse, the gear shift indicator on the panel doesn't light up, which leaves the drivers unaware of the gear their vehicles are in. But despite all the problems with the instrument panel cluster, only the faulty gear shift indicator was addressed by General Motors in 2005 when it recalled at least 7,000 units to reprogram the instrument panel cluster for free.

Two Most Common Gripes with the GMC Sierra 2500 HD

When Americans want a truck that they can count on, they turn to GMC. For many years, the all-American brand has been churning out some of the most reliable pickup trucks in the market. The GMC Sierra 2500 HD is the pick of the litter. Capable of being a reliable workhorse yet classy enough to be used as a personal ride, it's easy to see why the 2500 HD is a top performer. With so many years of manufacturing experience behind it, it's really hard to find fault with the 2500 HD. Still, no ride is ever truly perfect, so we brought together the two most common complaint people have had with the truck to make sure you are well-informed.


Inaccurate and faulty instrument panel

This problem was observed with the 2004 edition of the GMC Sierra 2500 HD. Most of the time, the problem lies with inaccurate readings given by the gauges on the instrument panel. In the very worst cases, the gauges on the instrument panel fail to work at all. While it is more an annoyance than a danger so far, the lack of knowledge on the states of the engine could lead to problems in the long run.


The quickest solution is to have the wiring in the instrument panel checked as this often fixes the problem up completely. No recalls have been issued for the problem as it is actually very rare. Some dealers are willing to fix the problem if your truck is still under warranty.


Excessive oil consumption

Affecting the 2002 release of the GMC Sierra 2500 HD, this problem is proving to be both costly and dangerous. It is costly because it necessitate constant refilling of the oil, and dangerous because it could cause trouble for the engine when left unchecked. Most have found the fault to lie in the engine itself-specifically with the pistons.


Again, no recall orders were issued. However, GM honors the 150,000-mile warranty on its trucks, and gladly takes care of the necessary repairs to make the problem go away.
