Car won't start after starting it with coolant temp sensor disconnected

Was going to replace coolant temp sensor sensor as fans don't work,and heating issues among other symptoms. Fan does not work while running air con either. fans work directly from battery. followed advice on net to disconnected sensor and try to start to see if fans work, suggesting faulty sensor. Just clicking sounds, no turnover. Reconnected sensor and still the same, just clicking sound now its worse, crazy dash lights, speedo shows max, locking or immobilizer issues. Afraid of burnt starter or destroying PCM. or maybe just need to reset it I hope? Please, any help, Scott 9/1997 Chrysler Grand Voyager LE V6 3.3lt.

Try a boost first before taking things apart,sound like low voltage.
Now about the fans.Sometimes it's easier (if the fans will work with voltage applied) just to install a relay and fire it off the switched power wire at the A/C compressor.Use this relay supply to voltage to the fans when the compressor runs.Want fans when not using A/C?Run a "in rad hose" temp switch and run that wire to the same relay to run fans when temp rises.Think after market hot rod stuff and keep it easy and simple,

SOURCE: replacing radiator fan motor on 2000 chrysler grand voyager

Disconnect the wires leading to both of the fans. Remove the cross-member that goes over the radiator. Remove the four bolts securing the fan assembly and lift it out.

It sounds like a bad connection in all honesty. if you havent replaced terminals do that. any corrosion you should clean check the cables also and see if they are corroded ander neath the coating I have seen terminals that were pretty tight but yet not enough to crank. I truly believe that is where your problem will be found. please let me know.

1996 ford probe is overheating, the fan won't come on


You have one of these:

- Blown fan Fusible
- Blown fan Motor
- Water temp sensor is shot

i won't say Blown headgasket or too low coolant level on the system because you have the fan not starting at all. that the root of the problem, do your engine overheats at high speeds? highway?

How to tell if you have a bad coolant temperature sensor?


You can oh it, measure the ohms with a resistance or oh meter. Typical, at 70* F, the resistance would be 1000 ohms, use your model service data.
The sensor may have two sensors in it. One for the temp Gage, the other for the computer.
An other kind of sensor is a basic on or off, open or closed contact. This is used on dummy lights and to turn on the radiator cooling fan.

New coolant fan and new control module but coolant fan does not work on my 2002 ford escort zx2


Try checking the fuse box under the hood. It should have a fuse marked cooling fan or cooling system. If the car does start, that means the computer isn't out, but maybe there is a bad relay by the fan or in the circuit or even the temp sensor may be bad. The fan won't run until the temp is high enough; usually by the time the thermostat opens.

My coolant fans don't work. What should I look for? I'm bringing it to a repair shop a mile away. Will it be safe to drive it that far? The temperature here is about 100 degrees outside now.


Hi,
If you start out with a cold engine, the Bonneville should not overheat traveling one mile, with out the A/C on.
If you are in stop and go traffic, roll your windows down, turn heater on high temp and high fan, and shut the Bonneville off at stop lights.
Watch the heat gauge.
The coolant fans not working may be a fuse, relay, or temperature sending unit switch.
Best Wishes,
Wayne

My 1999 toyota camrey just started overheating all of a sudden. I added water, don't see any leaks. The fans won't come on until I turn on the a/c then both fans come on. I drove it down the road...


well it sounds like your coolant temp sensor is bad that is what turns your fans on and on also since you are going to loose rad fluid when you change sensor replace thermostat to simple and cheap both thermostat usally right were the upper rad hose meets engine block aka water outlet and the coolant temp sensor is located in the side of the block also cheap and easy to change


if it helps please leave 4 thumbs up

2000 bettle 1.9L turbo will only start if you unplug coolant temp sensor


Hello and welcome to FixYa!

If that's the case, I strongly suggest that you replace the coolant temp sensor. Looks like it's faulty and grounding the circuit. The car's computer can detect it that's why it won't start but once you disconnect it, it will for the coolant sensor is bypassed.

Hope this helps and thank you for using FixYa! Have a good one!
