If you mean the engine temp guage, it's probably due to a faulty sensor

My 2007 Suzuki forename with 56,000ml. Ac running hot and engine running hot. What to do?


forename?
07 forenza (seems all posts are for this 1 suzuki)
a problematic car for sure....?
in what country, car has 6 engines, but 1 in USA>
so cant help you lacking where you are, (name a country,not your IPaddress)
we have the 2.0L engine, in USA< this is a USA forum so......??

ok the computers in your car are way smarter than say 1988 Samurai.
the PCM that runs the engine, for SURE cuts AC to keep engine from self destructing!! AC can do that,,,,,,
want a cracked or warped engine head ?
no.
the PCM cuts the a/c, and if engine is overloaded. or overheated
so forget the A/C
fix engine overheating (primary issues)
and guess wha?t , that gets worse, so delaying the fix
a $5 part compounds to $3000 new engine.
why not just get car fixed.???
"we cant teach you 50 years of engine problems in 5min time."
best post ever that.. here.

1: fuses good? check them it means.
2: water leaks?
3: levels wrong? (in actual rad, cold tested)
4: fan belts loose?
5: bad thermostat
6: bad water pump, impeller rusted to zip, do to abuse.
7: over heats parked only or moving fast or only up hills,? key facts if only parked the fan is dead.
8; lots more, but i end here

Engine Temp indicates in acceptable range, but am unable to touch the engine, radiator area because it is so hot. I suspect the auxilary fans are not operating. Where should I look for a problem and a fix.


Most engines today run very hot intentionally (an engine is a heat pump and is most efficient when the most heat is being made, but below the heat level that will cause it to self destruct) Many competent shops have a "heat gun" that can accurately determine if the engine is too hot, or normal. If a fan problem is detected, the system needs to be tested to determine if it is the fan motor, relay, sensor or wiring/computer that is causing it. Since your gauge reading appears normal, you may not have a real problem, aside from that you can't touch the engine when it's hot, but you don't do that much while driving!

Coolant fan runs while driving. No over heating.


Hi Benjamin:
Sounds like it's working as intended.
The fan will be controlled by a thermostat or temperature activated switch.
.It will run when the engine gets hot, and turn off when the engine is at the lower operating temp range.
If it was me, I'd be humming, "Don't worry, be happy".
Cheers.

I turn the key on start position let the key go but stil start but dosent run enles i step on trutel


This is a symptom that indicates the auxiliary air valve that opens to help the engine get more air and fuel when it is cold is not opening or its air passages are plugged.

Normally if it is the aux air valve it only gives this trouble with starting when the vehicle is cold. If it starts ok when the engine is hot from recent running. That makes it more likely.

I have had a stiff steering for some time now and its most likely the steering rack electric pump at fault, but with out any other indication. But now there is heat smell coming from around the alternator...


if the engine rpm drops low to illegal rpm , below, 800 rpm hot.

that is engine problem or parts seized. accessories.

we drop belts and turn each by hand, not smooth to turn is seized.

or use IR pyro gun to see what is hot.

or my $5 expensive stethoscope, i listen to each accessory

front and rear, to see if there front and rear bearings are screaming

or its just a loose belt.

why not get car serviced,this is like super easy stuff for any mech.

1997 Camry 4-cyl fan works but heat very weak - coolant level ok


Probability 1) The thermostat is probably stuck open, coolant is not getting hot enough from the engine to provide heat.

Starting from cold, allow the engine to run and warm up. While doing this, feel the upper radiator hose - you should be able to feel the coolant heating up to the point the hose is uncomfortably hot. If it gets that hot, then go to next step.

Probability 2) The heater core flow is restricted, not allowing full flow of coolant into passenger compartment.

There are 2 smaller heater hoses that run to the firewall. Are either of these hoses getting hot? Both sides hot indicate full coolant flow. Both sides cool indicate heater control valve not opening fully.

Cooling fan runs even after motor turned off


This is perfectly natural for the fan to continue running when the motor is turned off. I have seen them run for up to 15 minutes depending on how hot the day and the engine are. If it is not cutting off at all then you may have a problem in your heat sensor.

1985 fordf-150 inline6 wont shut off


if it seems to be stumbling when you turn it off but keeps running then you likely have carbon buildup on the valves, pistons or plugs .. the carbon stays hot and keeps the engine running even without spark .. usually if you hit the gas once it cools the hot carbon and the engine quits .. i suspect your f150 is never run fast .. a romp in passing/second gear once in a while usually keeps it clean .. there is special cleaner you can run thru to clean out the carbon .. you can get that an any auto parts store .. make sure the plugs are the correct heat range .. plugs that are designed for oil burning engines stay cleaner but may be too hot .. that can cause the same problem ..

now if your engine runs on smoothly with the key off then i would suspect a problem with the ignition switch or wiring
