Perfect time to try and cash in. I got the pleasure to drive a very low mileage gnx in college. It was owned by a cell phone repair guy.....this was late 90s so you actually took you phone back to the store for service......not just them ship you a replacenent......but it was numbered in the mid 200s, only had like 3xx miles on it.......he knew from previous talks I was going to school at Northwestern College. Now call University of Northwestern Ohio, so he asked if I could take it run and run some good injector cleaners and stuff.......so I did, pulled them, ran them through the ultra sonic cleaner......they were very gummy and had almost no flow at first. But man when I took the car home and I set it loose on cable rd at a red light I was across 3 1/2 lanes of a 4 lane road b4 I could reel it in on those street tires.......it was very very surprising the power that little motor
I would be surprised if it was not the original fill of coolant. Many collectors are not big maintenance guys, because they believe that if if they are not driving the car, no maintenance is required. And there is some truth to that, depending on how it is stored. Climate controlled conditions make a big difference, especially in states with extreme weather conditions. then again I have seen them stored wrong, and be in worst condition than if they had been driven... Buyer beware when purchasing any low mileage vehicle.. JW
It was green but the water the factory used must have been piluted because mine was muddy in color after a few months. Gave it a good flush & fill when new & still nice & green with 1800 original miles & 35 years. Jim is right on maintance, I guess I should give it some! Lol
The only GM vehicles that is does reasonably well in have dry intakes on them. The rest of them made a lot of us a lot of money lol. I bought an 87 GN new and still have it. 60 or 61k miles now, but not very many miles since the late 90’s. The coolant system stayed green until I started changing it at the regular interval (3 years). The key is not to let the mud start building up. Change it while it’s green. And that reminds me, it’s probably time again. I like that the A/C in the GNX works and is still R12. The conversions to R134A never seem to blow ice cubes like R12. My compressor leaked so I bought a seal kit and resealed it and and kept it R12. I’d like to have that GNX. But it might as well be $10 million! And then what do you do with it? Save it for the next guy?
Gm motors casted in Mexico in the 80’s n 90’s had issues with the casting media being stuck in areas of the block and only coming loose after a few years in service. We had a new Silverado in 88 we swore had oil/atf in the coolant and it took several tech’s to determine what was in the coolant. A good flush, I mean a 2-3 hour flush finally cleared the residual casting sand. Never had the issue ever resurface once flushed
