ACDelco GM Original Equipment 15-11073 Engine Coolant Thermostat and Housing Assembly

Que despejó todas mis dudas, con respecto al riesgo de que no fuera, el producto adecuado, me gustó mucho que era nuevo

OEM Thermostat for my 2004 Colorado. My truck used to run about a little over the 1/4 mark on the temp gauge but with this thermostat it is now closer to the half way mark which is indicative of the update they did to these to bring them up to 195 degree instead of 180. I was getting a P0128 code so my original thermostat was stuck open. To replace this, loosen your lug nuts on the drivers side wheel, jack the truck up on the drivers side, place a jack stand underneath the frame rail for safety, remove the wheel and the wheel splash shield held on by 6 plastic clips. Place a bucket or a catch pan underneath the truck and remove the lower radiator hose at the radiator. This will allow you to get rid of the old coolant that can accumulate sludge. Then also run a gallon of distilled water through the radiator and let it drain out. Also remove overflow bottle and drain that and clean it. I used two 9 inch long 1/4 extensions along with a swivel 10mm 6 point socket to remove the bolts. Once bolts are out pull the old thermostat housing away and the hose off the truck, so you can then have access to remove the stubborn clamp better.. Make sure you remove the old o-ring if it stays on the engine block. Wipe clean the mating surface. Put it all back together and fill with almost 2 gallons of Dex-Cool which you can also get on Amazon for a great price. I got rid of the stubborn clamp and used 2 regular worm type clamps I purchased at Vatozone. Easier to deal with than the OEM clamp.Tightening them from underneath the truck with my long extensions. Truck now runs about 2 tick marks shy of half way.

Glad to spend a few extra dollars for the ACDelco thermostat. A quality piece, and the rubber O-ring stays in place during installation. A two hour job to install on a GMC Canyon (requires left front wheel and fender well removal), no installation surprises. Old thermostat was stuck open. The new thermostat now regulates the temp just over 1/2 on the gauge. Very pleased.

Worked like a charm! Quick shipping. Thank you.

Fixed my issue of to cold coolant temp. I had a check engine light for coolant temp being too cold. My old thermostat was stuck open tank goodness instead of shut bc I could still drive it while the part came. It was the perfect fit and it has been in my truck for at least three years, so I'm gonna say the quality it very good. It returned the Heat level back into operating range!!
