1999 Gmc S15 problems
The Chevrolet S-10 is a compact pickup truck produced by Chevrolet. It was the first domestically-built compact pickup of the big three American automakers. When it was first introduced as a "quarter-ton pickup" in 1981 for the 1982 model year, the GMC version was known as the S-15 and later renamed the GMC Sonoma. A high-performance version of the latter was released in 1991, called "Syclone." The pickup was also sold by Isuzu as the Hombre from 1996 through 2000, but only in North America. There was also an SUV version, the Chevrolet S-10 Blazer/GMC S-15 Jimmy. An electric version was leased as a fleet vehicle in 1997 and 1998. These models are sometimes internally referred to as the S/T series to denote two and four wheel drive models respectively (similar to the full size Chevrolet C/K trucks) despite all versions being badged with 'S' nomenclature.
In North America, the S-series was replaced by the Chevrolet Colorado, GMC Canyon, and Isuzu i-Series in 2004.
The S-Series ended production in Brazil in 2012, being replaced by the Chevrolet Colorado, but still with the name S-10.

Common 1999 Gmc S15 problems
The GMC S15 1999 has been reported to have several common problems based on complaints from its owners. One of the most frequently mentioned issues is related to the engine and underhood, with the oil sludging up and causing the truck to sound like it's coming apart when started in the morning. This problem might be due to a cracked oil cooler inside the radiator, allowing coolant to mix with the oil. The sludge typically accumulates around the oil filter and cooler lines.
Another common issue is related to the distributor, where oil may seep from the base of the distributor, causing a 99-cent problem. Replacing the rubber O-ring on the distributor housing can often solve this issue.
The fuel system also has reported problems, with the fuel regulator in the fuel filter being a possible culprit. In some cases, changing the fuel regulator has resolved issues with excessive fuel and the P0410 code related to the secondary air injection malfunction.
The GMC S15 1999 has also been reported to have problems with the ignition system, including issues with the ignition module, coils, and plugs. In some instances, changing these components did not resolve the missing cylinder issue, which was accompanied by high crankcase pressure and smoke coming out of the dipstick.
Lastly, the GMC S15 1999 has experienced problems with the cooling system, specifically with the heater core. This issue can cause antifreeze to leak over the front part of the engine, and there may not be a simple way to bypass the heater core.
These common problems with the GMC S15 1999 are based on complaints from owners and may not represent all issues that could arise with this vehicle. It is essential to maintain regular vehicle maintenance and address any problems as they arise to ensure the longevity and safety of the vehicle.
