Hey all,
My radiator has been the cause of some troubles recently. My car has been heating up to excessive temperatures, now that it is summer time. In the winter it hangs out around 80, but in the summer it hangs out just above 100. Lately it has been heating up to around 120, usually turning on the heater lowers the temperature down, except sometimes it takes a lot longer and doesn't bring it below 100, which it usualyl does when I turn on the heat. I feel like the overheating is boiling away some of the radiator fluid. Does anyone have experience with this? My radiator fluid light comes on after not driving for a while, and usually stays on for a minute or so, before turning off. I changed all my air filters, and oil and filter, but there wasn't much of a change. Adding fluid usually helps for a while, but after a few days its the same thing. Is this just overheating? Or could it be a leak? Or is it overheating caused by a leak? Are there any known weaknesses in the line where I could look for leakage? Thanks.
