me and my friends are contemplating going on a road trip.almost 20 hours of driving.but we dont have a water pump, can you drive without one?
You can't go more than a few blocks without the car overheating if your pump is not working. Working or not, I guarantee the car has one. Unless, of course, you are being silly, and really own a car with an air-cooled engine!
you can drive 10 to 20 minutes with out one and then walk the rest of the way
whether it's safe depends on what part of town you'll be in after the first half hour, cause your engine will seize up stop running at that point. basically you'll convert a repairable engine into yard art.
Not unless you intend to spent about 4 days walking the 19 1/2 hours that will be left of your trip after the engine seizes up.
Safe - Yup Because you wont be driving for long, your engine temp will go through the roof fairly quickly and probably cause the head gasket to blow/engine to seize. It wont happen within two mins as the engine need to reach temp first and even without a pump it will circulate to a slight degree, but it is slight and NOT to be trusted or relied up, watch the gauge and how quickly after starting it goes into the red. Buy another water pump, get a fresh gasket, fit it, refill your system and enjoy the road trip.
