My 1996 Ford Taurus is running cold but the thermostat is working correctly?

Answer 1

If by "running cold" you mean that the thermostat always shows a "C" reading, it may just be fine, as most models of this type are made to run colder than most. If, however, you are experiencing engine cut-out, then there are a few possiblities; one may be that you have a radiator leak, or that your radiator has water and not enough anti-freeze. Most people make the mistake of putting water in the radiator, instead of anti-freeze when cooling down an over-heated car, but anti-freeze, alone, should always be used, as water not only causes rusting to occur, but it can also compromise the effectiveness of the anti-freeze, as it becomes too diluted. Today's ant-freeze comes "pre-diluted", so one never needs to add water. If, by chance, someone HAS added water at some point, not realizing this, your best bet would be a radiator flush, with all new anti-freeze. Keep in mind that since it is against the law to drain and discard your own anti-freeze, a flush replacement of fluid would be done at a place such as Jiffy Lube. Their prices are quite worth the investment toward preventative measures oregarding further problems. Look under the car for any visible puddles, or leaks. If none, do the flush. THIS IS ONLY if your car is experiencing cut-outs. If not, you're good. Don't worry.
