Recently my NA 1.6L jetta has been having large problems with overheating, while the warning light has never come on (always stopped it ~7/8 way by kicking on the heat) it is getting very annoying. I was wondering if a turbo radiator, or another option is available. Also wondering what people have tried as far as upgraded fans, the stock fan is not moving very much air.
Now the oil problem. When going up hill during one of these higher heat periods the oil warning will buzz one time only. Never continues, just one quick buzz and flash, until today when I got 3 out of it, was doing 65mph up a 4.5% grade hill when it went off. Check the oil level, it is actually slightly high, 15-40 weight oil, about 1k left until the next change. Any ideas??
now it overheats (>5/8 of gauge) even at hiway speeds, but the radiator fan kicks on low when the gauge reads (~7/8), which would indicate that the gauge may be incorrect.
