My car keeps overheating, i've replaced the top hose, water pump, and thermostat, what else could be the problem?

The unlikely one is the head gasket. Do you have water in your oil, do you have mayonnaise on the oil filler cap?

If the area under the thermostat is dry, the most likely issue is water pump failure. Empty the system, backflush the radiator and heater hoses with a garden hose. Replace the water pump and thermostat. Fill the system with coolant, turn the engine on, heater to maximum temperature and keep topping up the radiator until the coolant is hot and the thermostat opens. Squeezing the top and bottom radiator hoses also helps to get air out. Turn off the engine and top up the radiator one last time. Put the cap on and then top up the expansion reservoir.

One thing often overlooked with overheating issues, make sure the radiator fan is working properly.

Connie, Were the radiator,water pump and thermostat replaced to try and fix the over heat issue or as maintenance. Engine overheating can be caused by a lot of things, Leak in cooling system, air in system, bad rad. cap, slipping belt, faulty thermostat or installed upside down, faulty water pump, plugged radiator (inside/outside), collapsing rad hose, faulty cooling fan, leaking head gasket, sludge plugging engine water passages, poorly tuned engine, etc..
Take into a good shop for diagnoses and estimate for repair. Check the attached links,instruction and guides, Good luck

The engine gets cool water from the lower hose. And dumps hot water back in the radiator thru the top hose.

The water won't come your the engine until the thermostat reaches the appropriate temp.

After the thermostat opens and the water level drops in the radiator you can fill the radiator.

Hi ytabaja97,
Sounds like the thermostat on the hose that goes to the top of the motor is stuck closed, or does not open completely. Try replacing the thermostat. Make sure it is correct for your Jeep, and that the seals on the thermostat housing are replaced correctly.
Hope you have no more overheating problems.

!st check and make sure the water is flowing in the radiator, then check
the timeing, Mazda will run hot if the timeing is rong.

CHANGE THERMOSTAT or maybe bad water pump? could be pluged heater core

COULD BE THERMOSTAT IF TOP RADIATOR HOSE IS NOT HOT AND BOTTOM RADIATOR HOSE GOING TO WATER PUMP IS HOT THE THERMOSTAT STICKING PARTIALLY CLOSE.IF TOP HOSE IS HOT THE RADIATOR,ENGINE BLOCK HEATER CORE NEED FLUSHING OUT.IF WATER PUMP WEEP HOLE LEAKING REPLACE WATER PUMP, FAULTY WATER PUMP WILL CAUSE ENGINE TO OVER HEAT.REPLACE RADIATOR CAP MAKE SURE YOU HAVE 50 / 50 MIX SOLUTION ANTIFREEZE AND WATER IN COOLANT SYSTEM. IF ALL LOOKS GOOD CHECK ENGINE OIL ON DIP STICK, IF OIL IN DIP STICK LOOK LIKE MILKSHAKE YOU HAVE BLOWED HEAD GASKET THAT WILL CAUSE ENGINE OVERHEATING WHILE DRIVING CAR IN SHORT DISTANCE AND ENGINE OVERHEATING.

Overheating can be numerous things: Fans not working, water pump, thermostat, overflow cap, and the list keeps going. When the engine is running and heats ups, feel the heat of the top hose, if the hose isn't hot, the thermostat is most likely stuck open and needs replaced. If it is hot we know you have circulation. The cap on the expansion tank may be defective, if it can't hold the pressure of the water, it will release at the overflow cap if the cap is bad. Also check the coolant level.

The thermostat on the grand move is on the bottom hose next to power sreering pump above alternator

remove coolant.remove thermostat remove bottom radiator hose to water pump.put a empty container under the radiator.take a water hose put it where thermostat goes flush out the rust in block.watch the water as it come out the water pump .if stream water is small keep flushing until you get a study sream of clear water. also flush out radiator. lower water pressure dont flush radiator it with high water pressure you could burst it. make clean the over flow jug .make sure it not stopped up.put in a new thermostat and radiator pressure cap. fill radiator with half antifreeze and half water.bleed the coolant system.
