Can a jeep run and drive without a water pump??

ANSWER : Driving or running the engine without the water pump working to circulate the coolant through the motor will cause the motor to overheat and may damage the engine costing thousands of dollars versus using a tow truck to take the vehicle to the shop that will cost a lot less. I would not recommend running the engine more than a few minutes at a time or you will overheat it.

ANSWER : Check fuel pressure. There are only three possible explanations: a fault in fuel supply (plugged filter, injectors, etc.); ignition system problems; and air induction including the idle air control valve, throttle position sensor, mass air flow sensor and vacuum leaks including the PCV and EGR systems. If obvious, and easy to check, possibilities do not reveal the fault, the recommended service to request is a rough running diagnostic and the responding certified mechanic will travel right to your location and get this diagnosed and resolved for you. It is also possible that diagnostic trouble codes have set and the mechanic will attempt to retrieve those using an appropriate scan tool. If you have further questions or concerns, do not hesitate to re-contact YourMechanic.

ANSWER : Check the power supply to the fuel pump, at the fuel pump terminals (as close as you can get) to be sure that the circuit actually functions. If there is power to the pump, but no operation, it is possible the fuel has oxidized, turned to varnish and other compounds, and basically glued the pump "shut". Also, it is not just a matter of air in the tank (oxidizing the fuel) but also moisture in the tank. Over so many years, the pump could be sitting in water simply due to accumulated water from condensation. If the tank has lots of water at the bottom, if it is a metal tank you might even need a new tank due to the possibility of internal corrosion. Although I suppose you could figure out a way to "unstick" a fuel pump that has sat in oxidizing fuel, and possibly water, for so many years, it is not worth it on account of safety and reliability considerations. If there is power and the pump doesn’t work, I would install a brand new pump and of course very carefully inspect the interior of the tank being mindful not to blow it up. Use a low power LED light…don’t use a 120 volt trouble light around fuel or, much worse, around fuel vapors. If you desire that the pump be replaced by a certified mechanic and the tank be inspected, simply request a fuel pump replacement. If you have additional concerns or questions, by all means please let us know.

ANSWER : Anytime there is no or low coolant in a vehicle, it can be very harmful to the engine. Low coolant can cause a seized engine or a blown head gasket.

It is recommended that you have the vehicle towed to a location to have the cooling system repaired. If you can, refill the engine with coolant, and if the fluid does not run out as quickly as you put it in, then you may be able to drive a short distance to a safe location, but it is not recommended.

If you need assistance, get a mobile mechanic, such as one from YourMechanic, to inspect and determine the source of the leak, and replace the water pump, if needed.

ANSWER : Hello. You can just replace the water pump in this case. Although, the cost of just the timing belt is fairly negligible in comparison to the total labor of the job. My estimator says the water pump is a 6.5 hour job. Multiply that by whatever the shop rate is and you have the total labor without parts. You end up saving about $100 or less on parts if you only replace the pump.

The deciding factor will be the condition of the timing belt. If it has problems, you won’t be saving yourself any money by reusing it. In addition, there are seals and pulleys that may need to be replaced as well.

Assuming all the related parts were replaced the first time around, there isn’t a reason you can’t reuse them. I would say you should weigh the savings of reusing them against the actual condition of the parts. This is best determined after a complete disassembly. Keep in mind, time estimates will vary a bit depending on many factors. Either way, the labor is the largest cost.

If you would like to have the water pump replaced, a certified professional from YourMechanic can come to your car’s location to perform this service at your convenience.

ANSWER : The fuel pump in the fuel tank is designed to have low pressure and high volume to feed the front fuel pump the right amount fuel. The front fuel pump supplies the engine with high pressure to the engine.

When you do not hear the pump run then the fuel pump is bad and should be replaced along with the relay. You should not have to replace the in tank pump if it is running. I’d suggest replacing the fuel filter as well.

I’d suggest getting this inspected by a qualified technician, such as one from YourMechanic, to diagnose your stalling issue and make the necessary repairs.

ANSWER : Hi there – I suspect your radiator is clogged or otherwise corroded so that it is not shedding heat as efficiently as it should. Idling with the heater on was getting rid of heat without loading the radiator. When you’re driving, the engine is generating more heat than both the heater and radiator can get rid of. Checking the difference between hot coolant going to the radiator (top hose), and going back into the engine (bottom hose) may show that there is very little temperature difference. This means the radiator is not doing it’s job, and need to be professionally cleaned or replaced. Good diagnostic effort on your part to avoid the obvious "it’s another Northstar head gasket" diagnosis! For confirmation, I would recommend an overheating inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

ANSWER : Hi there. It’s not recommended to drive a vehicle with a damaged water pump; especially if the bearings are damaged. If the water pump fails while you are driving, it’s possible your engine will suffer serious damage.
