First of all make sure that there is no air pockets left in the motor. these will cause an overheat right away.

the way to cure these is run engine with and radaitor funnel and once thermo opens, run the heater on high, this should take about 10 to 15 minutes.

WORST CASE SCENERIO:
You have a bad water pump!

If you are certain that you did not put the thermostat in backwards, Try lifting the front of the vehicle so that the radiator fill is somewhat above the heater...Then run it with the cap off and heater on high. Re-fill as necessary...the heater core may be air bound. Also check heater control valve to make sure there is flow into and out of heater core.

1999 grand am is overheating


Beats itself?? I really dont know what that means. the cooling fan should come on when the a/c is on. when the engine is hot, the radiator should be hot. turn the a/c on and feel the air coming through, it should be HOT, if not, there is a coolant flow problem.

u should check for a faulty thermostat first, they are only a few quid and easily replaced. if no change ur most likely faults are a blocked radiator or faulty water pump. u dont sayhow old ur van is but after the thermostat go to the radiator, when its hot check the bottom of the rad to make sure its hot, also brown water means u need to bback flush ur cooling system. even tho u have changed some sensors doesnt mean u got the fan switch sender, dash board sender and fan sender tend to be different sensors, so just double check.

Check to see if the radiator fan is coming on when the van gets hot.If it does not then on a 2.6 liter engine.look on the bottom part of the radiator on drivers side for a fan switch that could be bad and not letting the radiator fan to come on. On a 3.0 liter engine the coolant temperature sensor is screwed into the thermostat housing. And on a 3.3 liter and on a 3.8 liter engine the coolant temperature sensor is screwed into the front cylinder head. Anyone of these can cause the van to run hot and eventually die with no restart until the temperature has cooled down. Check the fan first with two jumper wires from the positive/negative post to the fan connector on a 2.6 liter engine (positive wire to open pin on plug,negative wire to insulated plug side. On all v6 engines hook jumper wires to motor. To the left side will be positive and negative to the right. Do not let both wires touch together while testing. If motor does not respond to direct wiring then replace it. Another thing to look at is the catalytic converter on van. Check the exhaust flow when the van is running cold and again when it gets hot. If the flow starts to slow down when the van gets hot then remove the converter(plugging up). After doing that run the van again to see if the van runs ok. Hope this will help you.

2000 Plymouth Voyager Overheating


The radiator cooling fan relay has most likely failed. It is underneath the air cleaner on the frame rail just behind the radiator. NO cooling fan = overheating. This is the first thing i would look at. Best way to tell is when the van gets hot see if the cooling fan is on. You will hear it running if it is coming on. It will set a code for the cooling fan relay also.

OVERHEATING


This could be a multitude of things:

Stuck closed thermostat.

Cooling fan not coming on.

Clogged radiator.

Low on coolant.

Water pump failing/leaking.

Head gasket blown, leaking exhaust into antifreeze.

Clogged catalytic converter.

Thermostat: If the Van heats up, then feel the upper radiator hose. If it's cold, then your thermostat is closed. Replace thermostat.

Coolant: If low, simply fill with distilled water and coolant. Low levels will let engine over heat.

Radiator: If there are cold-to-the-touch spots on the radiator after it should be warmed up, then a clogged is probably occuring. Have radiator flushed.

Head Gasket: If you smell exhaust fumes in your coolant reservois tank, then you got a blown head gasket.

Cat Converter: Only can be tested if off the car. Or you could try a non-contact thermometer. These are also good to testing cold spot on radiator or if thermostats are open.

Cooling fan: If mechanical it'll be spinning. If electrical, it should come on automatically with the A/C, or when it gets hot.

Water pump: Will be leaking from the front if it needs replaced. On a van, it's a tough job.

Good luck!
