![]() ![]() For 1998, an attractive new color combination has been added: a teal body with charcoal cladding. It also has a sports suspension, with stiffer springs and larger self-leveling air shocks. It has SUV styling cues such as lower body cladding, fog lights and brawny front bumpers. The $1200 Montana package, which accounts for 60 percent of Trans Sport sales, is for folks who wish they could buy a sport-utility but need the capacity of a minivan. Chevrolet offers the least-expensive model (though it can be ordered with enough options to equip it comparably to the other models), the Oldsmobile offers luxury items such as leather seats, and the Pontiac has sporty options such as the Montana package. The models are differentiated appropriately for each GM division. The sliding door openings are wider than those on the Chryslers, which makes access to the third row easier. The GM minivans are 5 inches narrower, which makes them easier to maneuver through parking garages and into narrow parking spaces. Overall length is similar to comparable Chrysler minivans. (Power doors were limited to long-wheelbase models last year.) For 1998, you now can order a driver-side sliding door on the regular-length model, as well as a power sliding door on the passenger side. All three Chevy, Oldsmobile and Pontiac models come in a regular length with a 112-inch wheelbase, and an extended length with 120-inch wheelbase. We drove an extended-length Chevrolet Venture LS. And OnStar, the revolutionary navigation, security and personal service system developed by General Motors, is available on all three minivans. Front-seat passengers now have the added protection of side airbags. Dramatically rising sales of these three all-new minivans show that their unique attributes and overall competence have not gone unnoticed by buyers.įor 1998, the fundamentals have gone untouched, but several attractive new features have been added. GM's minivan sales are still far less than category-leader Chrysler's, but the company's hard work has paid off in spades. Sales of the Chevrolet Venture, Pontiac Trans Sport and Oldsmobile Silhouette quickly soared to record levels. Then last year GM launched a lineup that kept the best of the old–the sturdy 3.4-liter V6 engine, the modular seats that can be removed individually, and the power sliding door–and changed just about everything else. Hope this helps.For years General Motors was an also-ran in the minivan category. If you just charge R-12 or 134a your system will have traped non -condensables and a large drop in cooling ability. Replace that bad valve core (with ac valve core not a tire valve) Now very very important vaccum the system and if no loss of vaccum in 20 min charge with manufactors recomended amount of oil and freon.If a system is low on freon (cycling in & out on low pressure switch) you can add a pound of charge with those small cans of same type freon no problem but when there is a leak and the charge has been lost or changing freon types you must pull a vaccum to properlly charge the system. Drain oil from compressor and replace with 134a oil. ġ34a high side pressure will be about 18% higher so most systems you need to change the high side cutout.The R-12 electric fan switch will be ok just make sure it is engageing the fan when the pressure comes up.You must check the condensor in front of radiator to make sure air flows easily thru it.On systems where the hoses screw on each side of the dryer I replace the dryer. A large class 8 truck or maybe a high roof van black on black and poor insulation might tax the system in the 90% range on 100 degree days but most systems never get close. Don't let the 94% eff rating of 134a scare you because that does not mean that your ac system will lose 6% cooling ability. I have changed hundreds of systems over to 134 without any complaints.
