take one end of your heater hose off the heater core and run it back to the intake port.
Disconnect the rubber hoses from the heater and the intake. Once the clamp is removed, take a sharp knife and split the rubber ends and peal them off. DO NOT pull on the heater core as you can damage the heater core. Take a hacksaw and cut the band off and replace the heater hose using new clamps.
The port on top of the water pump (or on the side in some applications) is the coolant intake for the pump which coincides with the lower radiator hose. some people hook a heater hose to the intake and to the pump but doing this you are recirculating hot water from the heater core back into the engine as the water pump pushes water from front to back coming through the intake and out the upper radiator hose. so in this instance already hot water is going to the heater core and straight back to the engine without being circulated through the radiator also your water pump is essentially getting water from two sources. i normally plug the water pump and run a hose to the radiator and to the intake. there isn't anything wrong either way. one hose from intake to heater core and the second hose from the heater core to either water pump or radiator. one will take longer for the heater core to heat up but will ensure on a hot summer day all the coolant in the system is being cooled. with pump to intake setup the heater will work faster on a cold day but you may have cooling or overheating issues on a hot summer day.
Cool the heater hose and then gently take it off
follow the top radiator hose to the intake manifold... there will be an elbow its connected to. take off the elbow and under it will be your thermostat.
check your heater hoses one connects to the intake on rear passanger side of the motor it is likely the intake cracked there is a recall on this issue if the intake has been replaced with factory intake it is possible that the intake gasket is leaking check the bolts to be tourqed to specs if gasket is leaking replace gasket Crown Victoria Plastic Intake Manifold Heater Leak Fix When the stupidly designed intake manifold cracks where the heater pipe sticks into the plastic here's how to fix it. You will notice the plastic around the heater pipe is connected to some plastic to the front of the car from it. Take a hacksaw blade and cut about a 1/2" groove in that plastic - just enough to get a hose clamp around the plastic circle that holds the pipe. Tighten the clamp and voila! No more leak.
The thermostat is on top of your intake manifold, on the front side. Locate the radiator hose that runs to your intake, take the hose off and the thermostat will be sitting on the manifold under the hose.
Wait until its cooled off, remove the hose clamps and the heater hose and the bolts holding the housing on. Be prepared with some rags.Also take off the air intake,the throttle body,wiring to the alternator,radiator hose, cover on the manifold
FOLLOW THE TOP RADIATOR HOSE FROM THE RADIATOR TO THE INTAKE, TAKE APART AT THE INTAKE OR NECK, THERMOSTAT IS UNDER HOSE OPENING
Yes, or take one of the hoses loose at the heater core and take it back to the motor on the other one. Shouldn't need a new hose.
changed mine today its close to the starter follow the bottom rad hose to the block theres two bolts 10 mm should do it take of air intake and remove heater hose from head just to get it out the way
Take both heater hoses off at the heater and the hose running from the front, attach it to the rear of the engine.
