Cadillac spans two very different families: the truck-based Escalade, which shares much with Tahoe and Yukon, and the sedans and crossovers — DeVille, DTS, Seville and STS with the Northstar V8, CTS and ATS on rear-drive platforms, and the SRX and XT5 crossovers. Many of the Cadillac parts we quote are for 1998–2012 DeVille, DTS, CTS and SRX, so we match the part to the exact year, engine and package on your VIN rather than the model name.
What’s different about Cadillac cooling and AC parts
- Northstar radiators, water pump (driven by its own belt off the cam), thermostat and crossover housings are sold by engine year, and the rear-mounted water pump belt and tensioner are a common replacement on DeVille and DTS.
- Escalade radiators differ by tow package and the 2015+ trucks use a different cooling module; 2007–2014 trucks are known for leaking radiator tanks and heater-hose quick-connects like other GM full-size SUVs.
- AC compressor and condenser orders on SRX, XT5 and CTS involve variable-displacement compressors with an electronic control valve; 2017+ Cadillacs use R-1234yf refrigerant, and Escalade ESV has a rear AC unit with its own evaporator and blower.
