On my 2001 Focus Zetec 2.0L, the radiator fan only worked with the air conditioning turned on (as in no low speed - engine would overheat while idling or in traffic, but was fine as long as the A/C was on). The fix was to replace the radiator fan resistor assembly located in the fan shroud between the fans.

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.

Coolant flows from the bottom of the radiator into the engine, out of the engine into the upper radiator hose.

My 88 Montero sport motor runs very hot but the temp gauge reads normal. Could it be a head gasket

run the fault codes to start with
next have the temperature SENDER unit check for correct operation
have a compression test done to check for head gasket/cracked head
check for coolant level at the radiator cap as the sender unit needs water around it to indicate properly or else it only reads the metal temperature that it is screwed into and may actually read a lot less causing you to burn the motor
I have experienced where the bottom plastic tank of a radiator has come off and the temp gauge went down with out going up that resulted in a burnt motor.

I have a 02 Grand caravan that has new radiator, termostat, one new fan. the temp gauge goes up to max hot the drops right back down in seconds. what could be the problem?

it could be you have an air lock in the cooling system
remove the rad cap from the rad, start the engine and let it run until the coolant drops (add to fill it back up) or until the coolant boils out of the rad spout.

maybe pull the heat sensor. -replace it OR clean it off, reinstall it.

My 1999 ford explorer's gauge says its overheating but you can open the radiator cap and it was only luke warm just started and drove 1 mile?

It is possible for the engine to be overheating while the radiator seems to be cool. If the thermostat is stuck closed, the water will not circulate to the radiator. Simple check. Remove the thermostat and place it in a pot of water. Heat the water on a stove and observe when or if it opens as the water heats up. If it opens before the water boils, it is good. While you have it out, you might as well replace it anyway.

1987 jeep Cherokee temp gauge moves when car starts then goes. Back to 0. I replaced temp sending unit what now

ever consider it's telling the truth, (an IR pyro gun (tool) answers that in 1sec flat.
if it is truthing ,then that means the thermostat is missing,
or stuck open or it has one of those abominations, a failsafe Stat.
or air pockets below the stat causing it to go nuts, and the coolant sender too, goes double nuts, because of stat and because the coolant sender don't work in AIR. see? FULL IS KING> is it.

of when dead cold is the Rad FULL>????? cap off?
if not, BINGO>?
then does the rad hose get fully hot with a hot engine.
hand touches top rad tube and hand flies off, bam, 180F+
that be hot. is it?
(look ma, no tools?)

if the coolant is at 180f , rad full
and the gauge reads wrong, it might be a bad gauge or wires to it.
but that 180f thing is #1 , is it?

Good mormning all< i have a 1600 4cylinder in my sami. when idleing the guage reaches on H on the temp but yesterday we took a temp gum from the maachinac and the engine temp read 152F (that was the...

1985? Samurai? (no vitara) NO YEAR makes the real hard.!

the dash guage is but a toy and not and instrument.
if fact it has no numbers on it, no 180F. markes
the gauge is reading hot because the 1 pin 1 wire, sender wire
for the gauge is grounded out, remove this wire from sender
and the guage, must go to low.
btw here is the G16 being gauged, FULL HOT.
the gauge and sender tests are in the FSM. read that.

here is the G16
the no num gauge.
here is the best way to measure engine heat.

see how well the RAD works, see this. big drop !

on the G16, we test the guage like his.
yours is near identical.

on you car pull the sender lug. stuck H.
guage drop. to L, sender bad. or WRONG sender (common)
guage at H, then follow wire, from it to harness, ahhh, all cut up
and bare and hitting ground, bingo.

According to my owners manual the following items should be checked.1coolant level 2 faulty temp gauge or gauge sensor 3 thermostat stuck in the closed position 4 faulty rad cap 5 blocked water passages in rad,hose,or engine 6 fan blades cracked or missing 7 faulty fan motor 8 improper ignition timing 9 improper spark plug heat range. I think I would start by replacing the thermostat after a good engine flush and replacing the coolant.Good Luck

2001 dodge stratus engine temperature gauge spikes occasionally

Look for a loose connection to the temperature sender unit on the motor.
If all connections OK, you may need a new temp sender unit.

No heat. Temp gauge barely moves, but hoses to/from core are hot

If the temp. gauge on the instrument panel is OK, test and eventually replace the temperature sender, and check the wiring to temperature sender.

Replacing the whole heater core is not a simple operation, test sender and wiring first.
