Heater problems 2009 dodge nitro v6.

Possible, with rad cap off, let vehicle idle until coolant fan comes on then shut vehicle off for 30 minute cool down. Top up rad, install cap and drive and recheck heater operation and any overheating.

Location of engine coolant temperature sensor

Automobiles: 2000 Ford Escort ZX2 4-cylinder 2.0L MFI DOHC

The "left" side of the engine is the driver's side.

The Engine Coolant Temperature (ECT) sensor is a thermistor (a device which changes resistance or voltage as temperature changes). The sensor detects the temperature of engine coolant and provides a corresponding signal to the PCM (Powertrain Control Module - aka "the car's computer").

The ECT sensor is mounted in the following locations (small Ford engines):

1.8L engines: in the cylinder head
1.9L engines: threaded into the heater hose inlet pipe
2.0L engines: at the left rear of the engine

2.0L Zetec Engine

(1) Partially drain the engine cooling system using a clean container. If coolant is in good condition, retain for reuse.
(2) Disconnect the battery ground cable.
(3) Disconnect the electrical wiring connector from the engine coolant temperature (ECT) sensor.
(4) Remove the retaining clip and the ECT sensor.


Fig. 1 Escort ZX2 ECT sensor - The retaining clip is removed (at the solid arrow). Withdraw ECT sensor by gently wiggling/pulling in the direction of the dashed arrow.

To install:

Coat the ECT sensor O-ring with clean coolant prior to installation.

(1) Replace the retaining clip and the ECT sensor.
(2) Connect the electrical wiring connector from the Engine Coolant Temperature (ECT) sensor.
(3) Connect the battery ground cable.
(4) Refill the engine cooling system. An inexpensive plastic "Radiator Funnel" will help with this task.

The coolant light is on in my 95 camaro. History: .July 2006 i flushed out the rad and then took it off the road aug 2006....due to financial constraints, not mechanical issues........Its in great...

Hello: If the light is for low coolant level and the radiator/overflow tank are full it will not hurt to drive it. The thermostat has nothing to do with the coolant level switch. The level switch will be in either the overflow tank or the radiator tank.

1989 bronco2; when making turns it cuts out and try's to die.

Test the fuel pressure regulator. Could be the engine coolant temperature sensor. My son's BII was doing that, we flushed the system with a flush kit from Advanced Auto, this cured the stalling. A friend had suggested changing the coolant sensor before we flushed, it looks like he was right.

I just got a 1995 Crown Vic. I had the radator coolent flushed and now the heater blows cold air? It was working fine before this service. Can anyone help?

Take cap off rad when cool enough to do so. Start the car with cap off & heater turned on,(not defrost) and let it run for a while, as in wait for rad fan to come on 2 or 3 times. Add coolant/mix as needed while doing so. My guess is that you have an air lock in cooling/heating system that hasn't been bled out yet. Once in a while just rev engine a little, for about 30-second to 1 minute to increase flow through system, to help bleed & circulation. You should start to feel heat coming. Only put rad cap back on after rad fan has come on after 2nd or 3rd time. Check return bottle & fill it to mark as specified. If that doesn't do it, take it back to guy who flushed it, he should know what he did wrong.
