Question about 1996 Ford Thunderbird LX

1 Answer

Engine cooling fan will not opperate

I replaced the stock oem radiator with an after market all aluminum radiator and electric fan. ( Note), the fan is rated at 1,530 cfm , at 12-v AC and only draws 13- amps and is connected to the cars own wiring harness for the stock fan, that was don over eight month ago. As of two weeks ago, the heater would blow out hot air, then cold , while at the same time my engine temp gage would start out at 143-145 degreez while doing 65-70 mph, while the gage is still climing past 230. I have since replaced the thermostat,coolent temp sensor, and coolent temp sending unit.. After refilling the cooling system and purging the system to get any air bubbles out, and running the engine up to 1500-rpm with the radiator cap off and using an exsternale temp gage w/ a wire probe lead sitting inside of the radiator filler neck, The coollent temp reached past 220 degreez while boilling out of the radiator, and the cooling fan still did not come on!!!

Check that you have a thermal switch to switch on the fan and not a temp sender unit. One completes the curcuit when a set temp is reached ,the other is a resistance unit that lowers the voltage which in turn reads hotter on the gauge.

    If I do have this thermal switch on my car; where would it be located in the engine compartmen?

  • Bill Boyd Jan 18, 2013

    The thermal switch will be similar to the temp sender unit sometimes it will have 2 wires to allow current to pass through to a relay. It may have one as it may be on the ground side of the relay. As to location it will be in the head . some times it is next to the temp unit in which you would have 2 units near the thermostst housing. But it will be in the head near the frontWork back from the fan and check the relay if you find one then keep going until you get back to the head. If you still have original wire loom the color wire at the relay/fan will probably be the same color at the sender unit

SOURCE: engine overheats when heater pipes connected

I think you could be right about there being air trapped in the system.
Or the heater core(radiator) is plugged.
Either way you need a pressurized radiator coolant pump to put the coolant in without air being trapped.
Although,i have seen it done by jacking the vehicle up high enough that the radiator was now higher than the heater core level, and then the coolant was put in.
But this is dangerous to try.

    Overheating when ac on

    If the engine is overheating when the A/C is operated it means your cooling system is marginal. Your radiator is probably blocked and now your cooling system cannot cope with the additional heat generated by the A/C radiator.(Remember the A/C radiator sits in front of the engine radiator) I'd recommend a cooling system flush and failing that, have the radiator cleaned by a specialist or replace it with a new unit.

    Finding the thermostat in a 1987 suzuki swift

    Not familiar with your vehicle but engines of that period will normally have them hidden under a fitting that probably is a diamond-shaped cast aluminum piece with one of the radiator hoses leading to it and held in place by two (rarely more) bolts.
    It will be either on the head or the block.

    Just follow the (large) hoses from the radiator and the one with a fitting as described will likely have the thermostat concealed under it.
