What would cause my explorer to break down

Thanks for the info., sorry to bug you, but do you happen to know if it's expensive to fix? Being on my own with three kids, on top of the truck being old, and falling apart, I'm wondering if I should just get rid of it?

Anything else wrong? If not much it's cheaper to repair until cost outweighs worth of vehicle! For this one NAPA has a decent pump for about 50. + coolant and belt, hoses maybe. Labor 'guesstamate' as i dont have flat rate here, 150. I say under 300. Assuming this IS the problem!!

Thanks for all your info, I don't know what to do at this point, I can't afford that, for my life really sucks right now, I don't even know what else could be wrong, I've only had it for a few months, so I guess it will be sitting for awhile, again, I thank you for all your help

U welcom, good (better) luck!!
