Because of its low upkeep cost, massive, size, and total versatility, the Chevrolet G20 was the top work truck choice from its debut in the 60s until its last year in the mid-90s. Launched after the Corvair Greenbrier Van, the G20 was part of GMC's line of heavy-duty vansthis was released alongside G10, the light-duty version. The G20's first generation model started with a 2.51-L 4-cylinder engine that can generate up to 90 hp, which was already pretty powerful at the time. It had a box-shaped exterior with a simple design, making it perfect for hauling cargo and transporting packages around town. To give the Chevy Van a more up-to-date layout, GMC gave a major facelift to their line of second-generation G20s by adding a longer wheelbase, giving the exterior a different design, and changing the standard engine to a more powerful V8.
Fast forward to the 70sin response to its competitor, the Ford Econoline, the third-generation Chevrolet G20 again received numerous add-ons and upgrades. It had a unibody style frame, stronger hubs and brakes, and a more powerful 4.3 L V6 that produced 135 hp and 235 lb.-ft. of torque. Throughout the 70s, the G20s were only slightly modified every year, receiving grille revisions, headlight-style replacements, and transmission upgrades. When the 80s came, the G20 stayed pretty much the same, except for a few exterior layout modifications and the addition of a fuel-injected system.
Even in the 90s, the G20 remained a top choice for caterers, plumbers, and everyone who needed a work truck that can carry huge equipment and travel long distances. GMC responded to the demand by making only a few changes to the previous models. It simply worked on improving the safety feature of the Chevrolet G20 by adding side airbags, 4-wheel anti-lock brake systems, and other convenience features. The manufacturer also shifted to automatic transmission and included air conditioning as a standard in all models.
Can I convert my Chevrolet G20 into a hotel? How is that possible?
There is nothing quite like a van as a choice for a mobile living space. First, it can seat five and has enough space in the back for all your luggage. If you are in for a camping adventure, get your G20 ready along with the following must-haves: food, water, sleeping bag, extra blankets, pillow, mobile phone, flashlight, and bug spray. When you have them all ready, the next step is choosing where to stay. Among the good parking spot choices are parking spaces, back roads, and a friend's driveway or garage. Make sure that the location you pick is safe, offers some privacy, and will not hassle or bother other people. Also, be sure that you will not break any local laws and customs. Lastly, be on the lookout for "No Trespassing" signs.
My G20 is leaking, and the engine frequently overheats. Help!
The water pump may be leaking coolant, which causes the engine to overheat. Coolant leak and engine overheating are two signs of a defective water pump. If you also hear rumbling sound from the engine area, then your water pump needs to be replaced soon. Your van needs a properly working water pump so that coolant is circulated throughout the cooling system in the engine. If you delay the replacement, the leaky water pump may cause the timing and drive belts to fail. When replacing the water pump, you also need to check the entire cooling system for damage, as water pump failure can be also caused by other problems in the cooling system. You should also inspect the radiator, cooling fans, coolant hoses and fitting, and fan clutch.
What causes engine stalling and failure to restart on a Chevrolet G20?
The engine problems may be caused by fuel pump failure. Aside from engine stalling and failure to restart, among the signs that your fuel pump needs replacement are internal leaking in the fuel pump, hesitation when accelerating, and excessive noise. When replacing the fuel pump, do not forget to replace the fuel filter as well. Be safe when replacing these two components to prevent gasoline, a highly flammable substance, from causing fire and injury. Make sure the battery is disconnected before you start replacing the fuel pump and fuel filter. And once your van has a new fuel pump installed, you can keep it running optimally and prevent early damage by replacing the fuel filter every 30,000 miles.
It takes about five days for my battery to run down after charging it. What's wrong?
Several factors may be causing it. For one, the battery may not get recharged while you drive your van; in this case, you may have a charging issue. It may be also an issue of age—your battery is too old to hold a charge. Battery replacement is the only solution here. Another reason for battery rundown is anything that drains power from the battery even if the ignition key is switched off (e.g., lights, accessories, shorted diode in the alternator, a module that fails to shut down, etc.).
