My son at college has a 97 Jetta and recently the coolant warning light on the dash came on. The engine temperature light did not come on. A mechanic said he needs a new radiator. How can we test the speed...
First of all tell your mechanic to relax and breathe in a bit... If the radiator needed changing the temperature of the engine would either go up and overheat or it would vary ALOT from cold to hot to cold to hot, etc. when the car is running. In 99% of the cases where the coolant warning light comes on, it just means that there is not enough prestone/coolant in the reserve/catch tank under the hood. On those models the said tank should look like a big white plastic ball with colored water in it. If it's empty, don't look any furter you just found the problem. Put some coolant in and check from time to time to be sure there actually is no leak in the system, cause even if there is no leak, there is an overflow system that shoots some out when the pressure is too high, so you will see the coolant level drop without having a leak. Just to be safe, have you son bring a gallon of tap water with him in case, as it will cost less than coolant if it leaks all over the place all the time, and it will do the same job as coolant if the ambient outside temperature is not under freezig point. Prestone/coolant is basically just ordinary water with a special type of sugar added into it to prevent it from freezing in the cold.
