I swap out the heater core and may hav installed the hoses wrong.I hooked up the hose from water pump to lower fitting and return hose on top fitting

It usually doesn't matter-it just circulates coolant through the core and returns it. But the hose going to the water pump is the return hose from the core. The other hose from the cylinder head or intake manifold is where the coolant comes from and going to the heater core. Take off the hose at the water pump and you will see a stream coming out with the engine running and the heater control on hot. Try this and if the stream is not good, try swapping the hoses at the core- I mean take the hose to water pump and fit it to the core's upper hose, and the inlet hose to the lower fitting. It shouldn't matter, but let us know.

The heater hoses are on the back wall behind the motor.The lower one is the inlet and the upper one is the outlet.They might not be that easy to get to.Try doing this with the engine cold so you don`t burn yourself.Hope this helps.Good luck.

Car overheats new radiator 2 t stats diffrent eng new water pump, had same problem with first motor cust cooked first motor filled cooling system with radicat plus overheats sitting in shop heats up real...

Okay sounds like you have a clog within the system, first of all, drain the whole cooling system, run clean water thought the top of the radiator, look to see when the water comes out nice clear, replace the lower hose if you have a petcock close that, refill the top of the radiator, until it is full, start the engine, with engine running turn your heater, let the car warm a little, then reopen the petcock or loosen the lower hose and let the water draw out a little until is pouring out nice and fast, then re-close the petcock and stop the engine.
try and get 40% of the water out, and replace it with 50/50 antifreeze fill to the right point of the cars specs.

How to change a thermastat 1994 ford escort with a 1.9 engine

1.9L Engine

CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
  1. Disconnect the negative battery cable.
  2. Drain the cooling system.
  3. Remove the air intake tube, crankcase breather and PCV hose.
  4. Remove the ignition coil pack and bracket.
  5. Remove the upper radiator hose.
  6. Remove the ignition coil pack bracket.
  7. Unfasten the heater hose inlet tube bracket bolt and remove the heater hose inlet tube from the thermostat housing.
  8. Remove the three thermostat housing attaching bolts, then remove the thermostat housing and gasket.
