General Motors has issued a Technical Service Bulletin to address an issue with the engine coolant pipe on certain Chevy Blazer, GMC Acadia, Cadillac XT4 and Cadillac XT5 crossover models.
According to the TSB document that GM issued this week, a small number of its 2021 model year crossovers may have a coolant inlet pipe that may present an obstructed threaded hole for the coolant temp sensor which could result in the check engine light coming on or a potential coolant leak. The following vehicles are involved in this TSB action:
Dealers are instructed to replace the coolant inlet pipe and the temperature sensor in affected vehicles. It is estimated that there are only 15 vehicles affected by this problem that will require repair parts. These repairs will take a little over two hours for certified service centers to complete. Some other vehicles may not need repair parts, so long as they pass a cooling system leak check.
Vehicles that do require repairs will need the following parts replaced:
- Engine Coolant Thermostat Inlet Pipe
- Engine Coolant Temperature Sensor
- Gasket, Thermostat Inlet Pipe
- Engine Coolant
- Exhaust Pipe Clamp
- Catalytic Converter Gasket
- Exhaust Muffler Gasket
The problems addressed in this bulletin may affect customer vehicles as well as vehicles that are still sitting on GM dealership lots. The TSB will expire at the end of each affected vehicles’ new vehicle warranty period.
The Chevy Blazer is built at the GM Ramos Arizpe plant in Mexico, while the Cadillac XT4 is built at the GM Fairfax Assembly plant in Kansas. The GMC Acadia and Cadillac XT5 are built alongside each other at the GM Spring Hill Assembly plant in Tennesee.

Another Barra Blunder…..seems to be quite a few recalls over the last 2 years…I wonder if it could be related to the legacy personal Barra had walked out of the company a few years back…..
Yup, business as usuall. Can these cars go two weeks without a TSB. I quit, after owning two Traverses. I wasn’t going for the third strike, I got a Honda.. So who is to pay if vehicle is past warranty.
I also blame Mary for sending these vehicles to be built in Mexico and others in China. like you said business as usual. Its all about making the money by using cheep labor and parts.
2021 Vehicles , looks like a high Recall/TSB year for GM
