Hi Roy, here's a couple of things to check. While running and at operating temperature, look in the overflow container and see if you see bubbles. If you see bubbles, you head gasket is leaking. It's blowing hot air into the cooling system causing it to overheat and disrupting the water flow causing no hot water to flow through the heater core. Check to see if the the upper hose and lower radiator hoses are both warm. when it's at operating temp. You may also have a plugged heater core as well. Check the operation of the blend doors of you heater controls. You should be able to hear them open and close.

blend door is inside the heat/ac box that contains the heater core that you changed. It is vacuum operated, so check all of your vacuum lines. There is a vacuum line that goes thru the firewall, right above or below the 2 heater hoses.

Car heaters not very hot

try changing the thermostat and make sure all the air is bled out of the system this should help your heat problem.before changing the stat with the motor at operating temperature grab the heater hoses to see if they are the same temperature or not.if they are the same then change the stat.if not the same temp then the heater core may be plugged or partially plugged and will have to be changed.still change the stat as they do get tired and won`t work properly.

How to install a thermostat in a ford ranger 4.0L engine?

Its easy follow the top radiator hose back to the engjne to the goose neck the t.stat is under this part Drain some antifreeze from radiator you don;t have to drain itall out Remove clamp from hose to goose neck Remove bolts holding neck on you will lose a little antifreeze in the prosses Claen all old gasket meterial off bolth sides this is important it must be clean Remove old t.stat check the tempature stamped on t.stat replace with the same or similar temp you don;t change this to much Install new t.stat and gasket you can use a sealer it won;t hurt Install goose neck but don;t over tighten you can crack the neck 10 to 12 ft lbs is all you need BUT THE T.STAT IS NOT USELY NOT THE PROBLEM WITH COOLING SYSTEMS you can try back flushing the system and putting new antifreeze first this may solve your over heating problem

I have a heating problem with my saturn 1995 and i already change the heating sensor

Replace the thermostat which is located inside the lower radiator hose on the block side.

Get the Stant 195*F thermostat. As long as you replaced the engine coolant temp sensor than the t-stat is the next thing to replace. Also as a double check make sure your dial on the inside of the car is properly actuating the arm to move it to heat.

My heat stop working,i was told it is the termostat can not find the termostat

the t-stat is located on the front side of the engine underneath. you actually have better visibilty underneath the vehicle. i would perform a flush prior to replacing any parts. if it was the t-stat, you would also have over heat issues. a t-stat is nothing more then a temperature sensitive, mechanical restriction in the cooling system. wax pellets heat up during the warm up process allowing the engine to heat more rapidly during cold start and push the valve open allowing for flow to the radiator. go to your local parts store and for about $10 you can get a flush chemical which will help flush your system of contaminants and corrosion and then refill the system with fresh coolant and distilled water. be sure that the system is totally full and bled or you will know the first time you take it out and it over heat due to lack of fluid.

Poor heat output motor runs cold

Check the hoses going to inlet and outlet to heater core. You may have accidentaly hooked them up backwards since you said you flushed the heater core out. Also did the barsleak have the aluminum filings in it?

Try changing the t-stat and make sure the coolant is topped off and no leaks first.
