What to do if your Escalade thermostat is not working?
How to Replace a Thermostat (video). Escalade Thermostat Wiring – If the thermostat itself isn’t the problem, it’ll be the wiring/sensor associated with engine water temp detection, or the coolant temperature sensor itself. If playback doesn't begin shortly, try restarting your device.
What happens when a thermostat fails on a GMC van?
When the thermostat, in your GM 4.3L, 5.0L or 5.7L pick up, SUV, or van fails, it does one of two things: it stays stuck open or stuck closed. If it stays stuck closed, your pick up (van or SUV) will overheat.
What is the p0128 code on a Cadillac Escalade?
P0128 is a relatively common OBDII trouble code. It is triggered when your Cadillac Escalade ‘s coolant temperature fails to reach the proper operating temperature. It’s a generic powertrain code, which means that regardless of who manufactured the vehicle, it’ll have the same meaning (1996+).
What causes the Check Engine light on on a Cadillac Escalade?
It is triggered when your Cadillac Escalade ‘s coolant temperature fails to reach the proper operating temperature. It’s a generic powertrain code, which means that regardless of who manufactured the vehicle, it’ll have the same meaning (1996+).
How much is a thermostat for a 2002 Cadillac Escalade?
The average cost for a Cadillac Escalade thermostat replacement is between $694 and $715. Labor costs are estimated between $83 and $105 while parts are priced at $610. This range does not include taxes and fees, and does not factor in your specific model year or unique location.
Why is my Cadillac Escalade overheating?
The most common reasons a Cadillac Escalade is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
What temperature does a thermostat work at?
Most engine sensors function at 150 degrees, and the computer ignores them until the engine reaches that temp. A 160 degree thermostat allows the sensors to work, and will open further at say 195 degrees than a 195 will. The hotter the coolant gets, the more the thermostat opens, allowing more volume of water to pass to the radiator.
What temperature should a 160 degree thermostat be?
Okay, so a 160 degree thermostat opens 30 degrees sooner than a 190 but my ultimate operating coolant temp is 212 - 218 degrees in which case both thermostats are open while the engine is up to temp.
How high should a thermostat be open?
Thermostats aren't just open or closed. They open according to the water temp. Typically the thermostat begins to open 3° - 4° F above or below it's temperature rating (meaning a 180° thermostat will open between 176° F and 184° F.) and will be fully opened at about 20° F above it's initial opening temperature.
Why use a lower temperature thermostat?
On performance applications it is sometimes effective to go to a lower temperature rated thermostat so as to compensate for the added power output from the engine modifications. But, you must be very careful when using lower thermostat ratings on computer-controlled engine applications.
Is the water temp on a stock gauge wrong?
The water temp on the stock gauge is wrong it is true that the water temp is not 160 but it isnt at 210 either the block temp is high but Comb. camber is lower causing the gas/air mix to be cooler. It does increase the life of the rings but decreases the life of your cooling system.
What happens if the thermostat on a GM 4.3 fails?
When the thermostat, in your GM 4.3L, 5.0L or 5.7L pick up, SUV, or van fails, it does one of two things: it stays stuck open or stuck closed. If it stays stuck closed, your pick up (van or SUV) will overheat. If it stays stuck open (or if it's missing), the engine will not warm up enough and the heater will not work (if its winter time).
How to tell if your thermostat is stuck?
CASE 1: If the thermostat is stuck open, you'll see the following symptoms: 1 Bad gas mileage. 2 If it's winter time, the heater will not work. 3 If your vehicle is equipped with a temperature gauge (and not just a temperature light), it will always show you a low reading or none at all. 4 Won't pass the state emission's test.
