No heat at all in my 2002 Ford Ranger

I have no heat in my 2002 Ford Ranger XL 2.3L. I installed a new thermostat but it did not solve it. Now I don't know where to go. Its cold and I need heat. Does anyone know where to go from here?

Was the thermostat put in the right way?,did you bleed the system from air? does your car have a water heater valve(open full-medium-off)?,is the heater core always on "on for hot water flow" but controlled by a flapper door that allows hot air exit to cab by flap position for heat temperature control??. I'd start by bleeding the system by applying water to the radiator while highest cooling system hose is partially open to allow air bubbles to get out and reconnect hose as soon as only water (with no air bubbles) comes out. Then I'd try the rest if the least less complicated doesn't work. Careful for electric cooling fans: it goes on even with the engine off!!!

Yessir, Open the hood and find your heater hoses when hot grab both of them while engine is running, you should feel heat like REAL hot on one or both of them... If it is on just one you have a restriction in the heater core. If they are both hot my bet is an air bubble in the heater core. You can park it uphill and open the radiator cap SLOWLY with a towel this will burp air that has made it to your radiator. OR you can turn off the engine let it cool and pull off the UPPER hose....Hold it higher than your radiator and then have some help and fill the tube with water this will force air into the tube from your heater core.

What would cause a 1994 Ford Ranger to heat to the L of 'NORMAL' on the gauge after a new thermostat was installed? It has never been past the r/m consistently.


if it is a genuine ford ranger thermostat it should be the same, however if it is an after market one (non genuine ) that may be the problem as thermostats have different "start to open" & "fully open" temperatures......hope this helps......cheers.

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

Ford ranger 2002 6 4.0 LTR truck over heating.


The water is from the thermostat housing, fairly common leak. The ticking maybe from the timing chain cassette. You may have already had the cam timing slip (the cam gears are not keyed, they are held in place by torque alone. The oil gauge sounds like an electrical problem (either sender or sender wiring).
