Thermostat is most probably no more good, or u have a serious air bubble in ur coolant system if it leaked or was repaired recently.
90% chance it's ur thermostat.

I have done the headgasket on my rover 75 with new piston it keeps over heating coolant comes out of header tank but my heater remains cold and pipes going in and out

Check if u have a heater full blast if u get a hot air comes out to it.....if not then water is not properly circulated it doesnt cool the engine if thats ok then check the pump and thermostat and try ti feel the return line of the coolant to the radiator if its gets hot or warm to touch (located on top part of the radiator) means if its just warm water is not circulatibg properly I dont have experience on 75 rover im just telling u how the coolant cools the engine or how does the system flows and its applicable to all cars that has water cooled engine there one exception the air cooled volkswagen hope this might help u out have patient.....lastly did u flush the system after u installed the head gasket? U have something drop in tge engine while changing the head gasket and its causing blockage just a reminder

You have still got air in the system.Remove the Feed back pipe from the header tank and wait for all the air to come out while the engine is running making sure you are toping up the header tank at the same time Dont allow header tank to run dry while doing this.Good luck

Check operation of hot water shut off valve for heater, but first make sure the engine coolant is full to the top. If coolant level sinks, the first thing to go is the heat

Jag s type 2001 the water header tank burted en toute and due to coolant the engine management systemreduced engine power until i stopped uppon cooling down i filled with lookwarm water and limped home...

Sometimes this bleed method is not enough.
Bleed air out of the very top water hoses on the engine (when cold!) whilst filling. Then run the engine for a short time, check tank level again and if required refill when cool enough to be safe, repeat this if water level drops in tank again. When water level in header tank stays constant run the car up to full temp. and see if problem is fixed. Then check level again when cool.

good luck. Hope this helps.

Running hot coolent is fine...

check for a blown head gasket it will sometimes pump air into the heads and make the coolant levels seem fine but in truth they are not and check the water pump for rusted fins make shure the water level sucks down during sharp throtteling of the motor if so the cooling system is fine as far as that goes but where to start

1.) tempature switch located on the motor it tells the ecu when to kick on the cooling fan

2.) fans spin freely without taking force

3.) thermostat it could be stuck closed due to someone at sometime only running water without antifreez and causing the pressure pin to rust and freeze the gate shut

4.) monitor the water levels if they go down suddenly as 1 gallon of water a week or 2 weeks its a bad head gasket you can see this on spark plugs as well

and for most your water pump make shure you get good heat from the heater at low running tempatures and start the car and monitor what the water in the radiator does (while its cold) the water in a car is over 195% and can easily do harm if the car is just warmed up not even close to over heating so you can imagine what it could do at an over heated state

but get the problem fixed or else you can result in blown head gaskets water in the oil piston breakdown do to rust in the piston walls and even worse complete engine failure

Heaters dont work on my mk3 golf cabrio

if the blower motor is gone u will get no air cold or hot.
If it is the switch you would hear the blower but maybe get no hot but just cold air or vice versa.

1993 Ford Taurus heat is cold at idle

Usually the sign of low water level in the radiator. The first thing to be starved of hot water when level is low is the heater. When you rev engine up this speed up quantity of flow and so some gets around the heater. Check level in radiator as well as header tank. Top up with the correct coolant.
