Changed the temostate

your overheating --low coolant --water pump--dirty radiator --coolant old --etc

Is there water coming out of the tail pipe?

does putting heater on hot prduce hot air.on full with fan on does it reduce temo?is ur radiator fan coming on? hard to give one answer.as dont know if its overheating in traffic or on the move?there could be air stuck in pipes slowing water flow.or a pipe/radiator blockage so coolant doesnt get to flow around engine so it gets hot.u could check radiator by touching see if hot or cold where pipes enter(prob switch off engine first) try bleeding system squeesing pipes to push air out

1. Remove mounting bolts and remove upper timing cover and gasket. Drain coolant into clean bucket.
2. Loosen the 4 water pump pulley mounting bolts. Loosen alternator adjusting and mounting bolts and remove the belt.
3. Remove the water pump pulley bolts and the pulley.
4. Remove the water pump inlet mounting bolt from the side of the block and then remove the 2 nuts attaching the pipe to the water pump. Remove the pipe.
5. Remove the mounting bracket bolt and then remove the dipstick tube. Plug the hole with a rag. Remove the right hand under cover and the power steering adjusting bracket ( if it has power steering).
6.Remove the 3 bolts and remove the water pump. Keep coolant OFF the timing belt (plenty of rags to soak it up)., Remove the O ring from the block.
7. To install a new pump, start by replacing the O ring in the block. Then the reverse of these steps.
8. Water pump mounting bolts are torqued to 11 ft.lbs only. Also replace the O ring on the dipstick tube and coat it with oil before reinstalling.
9. Refill the cooling system and run the engine up to operating temperature, with the heater running. This will force the air out of the system. Once the air is out top up the rad and replace the rad cap.

that would be the place to start, remove the readiator cap and fill the readiator then the over flow bottle, make sure the engine is cool before removing the cap, then fill the readiator and then start the engine with the cap off and top the radiator off again it would be a good idea to let the engine run untill the thermostat opens to make sure the radiator is full you will know when the thermostat opens when the top radiator hose get hot......good luck

1. Diconnect negative battery cable.

2. If the vehicle has an automate transaxle, remove the exhaust manifold before proceeding with the removal and installation of the thermostat.
3. Drain the cooling system. 4. Take out the bolts that hold the water pump feed pipe to the thermostat housing. 5. Lift out the thermostat-housing-to-water-pump feed pipe. 6. Pull out the thermostat. 7. Set the new thermostat in position. 8. Connect the thermostat housing-to-water-pump feed pipe.
9. Set the bolts in place that holds the thermostat-housing-to-water-pump feed pipe. Torque the bolts to 89 inch pounds. 10. Install the exhaust manifold. 11. Refill the cooling system to the proper level with a 50 / 50 mixture of distilled water / DEX Cool approved coolant. 12. Start the engine and check for leaks. 13. Make the necessary adjustments to coolant levels to assure optimum engine performance.

CHECK AROUND WATER PUMP AREA.AND THERMOSTAT HOUSING FOR LEAKS.THE MECHANIC WHO PUT THE WATER PUMP ON MAY FORGOT TO PUT SEALANT ON BOTH SIDES OF THE WATER PUMP GASKET CAUSING LEAKS.LOOK AROUND THERMOSTAT HOUSING FOR LEAKING.IF THERMOSTAT SEAL WAS DAMAGE DURING INSTALLATION IT WILL CAUSE LEAKING.IF ALL LOOKS GOOD CHECK FOR COOLANT LEAKS AROUND RADIATOR .CHECK RADIATOR TOP AND BOTTOM HOSES FOR LEAKS AND CHECK HEATER PIPES AND HEATER CORES HOSES FOR LEAKS.IF ALL HOSES GOOD.CHECK FOR LEAKING CORE PLUGS.

Ok, Take the overflow hose out of the overflow tank and opput the end in a glass or jar of water. Start the motor and watch gfor bubbles coming out of the hose in the water.. Little tiny smokey white bubbles mean you have a combustion leak into your cooling system. Possible head gasket seapage.good luck

Stick with me on this
1.Put the car on jack stands
2.Remove the exhuast manifold, Do not rotate the flex cuopling more then 4 degrees od damage will occur.
3.Diconnect the coolant inlet pipe from the water pump outlet hose, Disconnect from the engine, disconnect it from the thermostate housing and remove it.
4.lower the car back down of the jack stands.
5.Detach the brack booster hose.
6.Remove the timing chain cover and the tensioner.
7.Remove the heater outletpiper from the water pump.
8.Remove the water pump cover bolts.
9.Remove the water pump retianer nuts.
Remove the old gasket and clean.
10.On bench. Install the waterpump and cover but lreave the bolts finger tight.
11.Install back in car, leave water pump bolts looseto allow for positioning.
12.Install water pump cover to engine, tighten by hand.
13.Lubricate oringand install metal outlet pipe back into pump, hand tighten.
14a.Tighten the water pump to timing chain nuts
14b.Tighten the water pump cover to water pump housing bolts.
14c.Tighten water pump cover to engine block bolts.
14d.Tighten the radiator outlet pipe to water pump.
15.Install timing chain tensioner.
16.Install exhuast manifold.
17.Install exhuast pipe.
18. Fill it up and bleed the system.
Good luck
