Unless your vehicle is diesel powered you probably don't have a coolant heater.

Strange coolant leak from 09 Nissan Sentra.

It could be leaking from the heater core, under the carpet an down the side of the car??? Definately a weird one, i would suggest a cooling system pressure test, this will help pinpoint the location easier.

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.

Where is the engine block heater located & how do I plug in the engine block heater

i assume you mean the electrical wire to plug into a source.they are usually located somewhere around the battery area sometimes behind the grill assembly.sometimes in the same area but on the opposite side of the car.all you have to do is plug it into an electrical supply source such as your house electrical outlet using an extension cord that is rated for this type of application and outdoor use.the plug looks just like an electrical appliance that is in your house.

Can you show me a video on how to put in heater core for 1996 Nissan Maximal

What i have is the steps on how to put or replace the heater core. hope this will help you.

the core is located behind the steering column, meaning you mainly need to remove that. On more recent cars, the whole dashboard needs removal.

Older Models

Shut off power to the Maxima, especially the air bag system. Disconnect the negative battery terminal and wait at least 3 minutes for the air bag to lose energy.

rain the engine coolant from the cooling system. Use a clean container if you plan on reusing the coolant.

Disconnect the heater hoses from the heater unit inside the engine compartment. Remove the blower and cooling unit from the interior and then the steering member assembly. Remove the heater unit and the core from the unit.

Install the new core into the heater unit and reconnect the unit in the car. Connect the steering member, cooling unit and heater hoses.Refill the cooling system and connect the battery cable.

Newer Models

Unplug the negative battery terminal. Wait 3 minutes for the air bag system to lose power. Drain the engine coolant into a clean container.

Disengage the air bags from both sides of the car. Remove driver's bag by removing the steering wheel's lower and side lids and the Torx bolts from the wheel sides. Disconnect the passenger bag electrical connector from inside the glove box.

Disassemble the instrument panel. Remove all components and screws from the panel, then have an assistant help lift and remove the panel itself.

Disconnect the following heater, defroster and ventilation ducts on the rear and sides. Remove the heater housing and the heater core from the housing.

Reinstall the heater housing with the new core installed. Replace all ducts, the instrument panel and the air bags.

fill the cooling system and reconnect the battery cable. Let the Maxima

Coolant leak behind engine

The leak could be coming from a heater hose, head-gasket, or freeze plug. Get a good light, a couple telescoping mirrors or telescoping camera, and a coolant pressure tester. You will look for trails and follow them to the source. NOTE: You may want to put the front wheels up on ramps so its easier to get underneath. And remember those safety glasses.

Location of block heater cord on my 2003 chevy silverado

MIne was on the passenger side inside the wire loom next to the shock. You can get to it through the fender well. It just looked like a ball of tape and only the plug itself was exposed with the rest of it doubled back on itself inside the loom. It was actually long enough to stick out of the front of the truck.

I'm trying to find where my engine coolant heater electrical cord would be? I just bought this vehicle

Hiya...the factory install this block-heater option that's usually installed at the left side of the engine bay area.
Pop open the hood and look around the black square air-filter housing area found at the left side (or at the corner behind the headlight area)
There should be a black wire harness routed around the air filter housing--it may be 'hidden' underneath the air filter around that area...hope it has this feature if so equipped.
