Cooling System Parts and HVAC Parts for Cars, Trucks, and Other Vehicles
Your vehicle's cooling system keeps the engine from overheating, while its HVAC and climate control parts keep the cabin comfortable through every season. CBT Auto Parts stocks the cooling system parts and HVAC parts drivers search for, from radiators and water pumps to AC compressors and heater cores.
Every part listed is OEM grade or built to OEM specification, so fitment is never a guess, and aftermarket options are chosen for reliability, not just price. Confirm fitment by year, make, and model, then add thermostats, condensers, or coolant reservoirs to complete your auto cooling system. Orders ship fast worldwide, with support on hand if you're unsure which part fits.

Why Shop Cooling, HVAC, and Climate Control Parts at CBT Auto Parts
Generic claims don't keep an engine cool or a cabin warm, so here's what actually backs every order in this collection:
- Every radiator, compressor, and core is checked against OEM part numbers before it's listed, so the fitment data shown is the fitment you receive.
- Coverage extends past standard passenger cars into light trucks and select heavy-duty and race applications, keeping your vehicle's cooling system running whatever you drive.
- OEM and vetted aftermarket options sit side by side and are clearly labeled, so you choose based on your budget and your tolerance for risk, not guesswork.
- Orders ship fast and reach addresses worldwide, with tracking active from the moment a part leaves the warehouse.
- If you're unsure which part your vehicle needs, our team can confirm fitment against your VIN before you check out, not after.
Shop by Cooling, HVAC, and Climate Control Component
This collection is organized by component, with nineteen dedicated ranges covering every major part of your car's cooling system and climate control setup.
Radiators
A failing radiator is one of the most common reasons a car overheats. This range covers car radiator options across passenger and light truck applications, including aluminum and copper core builds, with radiator and hose kits sized to match factory cooling capacity.
Water Pumps
Without a working water pump, coolant stops circulating, and engine temperature climbs fast. You'll find water pump units for everything from daily drivers to diesel engine water pump applications, each matched to the correct impeller design and mounting pattern.
Thermostats
A stuck car thermostat is often mistaken for a bigger cooling problem than it is. This range covers standard and high-flow thermostats, plus thermostat housing assemblies, so the part and the housing it seats into arrive together when needed.
Cooling Fans
Cooling fans pull air through the radiator once a vehicle slows down or idles. The cooling fan and radiator fan options here include 12-volt electric assemblies for cars and light trucks, sized to the original shroud and mounting points.
Fan Clutches
Heavy-duty trucks and commercial fleets rely on a fan clutch rather than an electric fan to manage temperature under load. This section is built around truck fan clutch and clutch fan parts for major commercial brands, kept separate from the passenger fan range above.
Radiator Hoses
Upper and lower radiator hoses carry coolant under pressure and heat, and they age from the inside out, where wear is hardest to spot. The radiator hoses here include silicone and rubber builds, with rad hose and flexible radiator hose styles for tight engine bays.
Condensers
An A/C condenser sits at the front of the vehicle and is one of the first parts damaged in a collision. Condenser replacement parts here are matched by year, make, and model, with coverage extending to popular crossover and SUV applications.
Evaporators
When the cabin blows warm air even with the AC running, the evaporator core is a common cause. This section covers AC evaporator and evaporator core assy parts, cross-checked against heater core fitment where the two components sit close together.
HVAC Blower Motors
A worn blower motor usually announces itself with noise before it fails outright. The HVAC blower and heater blower motor parts in this range cover cars, trucks, and select bus and commercial cabin layouts.
A/C Compressors
The car AC compressor is the part that actually pressurizes refrigerant, and it's the most common AC failure point across the industry. This is the highest volume section in the collection, with car air compressor units for sedans, SUVs, and trucks.
Heater Cores
A leaking heater core is the usual reason for a sweet smell or a fogged windshield in cold weather. Heater core parts here are sized for cabin heat output first, with evaporator and heater core combination units where the two share a single housing.
HVAC Control Modules
When temperature settings stop responding or the climate display goes blank, the HVAC control module is usually the part at fault. This section covers the climate control module and HVAC module car parts, kept separate from the unrelated control modules used elsewhere in a vehicle's electrical system.
Cabin Air Filters
A clogged cabin air filter is the simplest fix for weak vent airflow or a musty smell inside the car. This range includes standard and activated carbon cabin filter options for cars, alongside cabin air filter truck applications.
Expansion Valves
The expansion valve controls how much refrigerant enters the evaporator, and a faulty one causes inconsistent cooling. AC expansion valve parts here are listed by application, including truck AC expansion valve coverage for commercial vehicles.
Heater Hoses
Heater hoses carry hot coolant from the engine to the heater core and are sized by diameter rather than by vehicle model alone. This section covers heater hoses in the common diameters drivers search for, kept distinct from the larger radiator hose range above.
Oil Coolers
Towing, hauling, and diesel use all put extra strain on oil temperature, which is exactly what an oil cooler is built to manage. The engine oil cooler and transmission oil cooler parts in this section lean heavily toward diesel and commercial platforms.
Coolant Reservoirs
The coolant reservoir is the overflow tank that absorbs pressure changes as the system heats and cools. This section includes coolant tank overflow and coolant bottle parts, paired naturally with the radiator and radiator cap ranges nearby.
Radiator Caps
A worn radiator cap is a small part with an outsized effect on cooling system pressure. Radiator pressure cap and radiator cap seal options here are sorted by pressure rating, an easy add-on alongside a radiator or coolant reservoir order.
Cooling Fan Motors
The cooling fan motor is the electric motor that spins the fan blade, and it fails independently of the blade assembly itself. This section covers radiator fan motor and 12-volt cooling fan motor parts for cars and light trucks.
If boost or intake air temperature is the issue rather than coolant, intercoolers are covered separately within our Engine and Powertrain range rather than duplicated here.
Built for Confidence: Fit, Speed, and Support
Every listing in this collection shows fitment by year, make, and model before you add it to the cart, so there's no second-guessing when you order cooling system parts at checkout. Parts that don't fit are accepted for return, support is available if you need help matching a part number, and most orders leave the warehouse within one business day. Whether you need engine-side components or HVAC parts for the cabin, the goal is the same: the right part, confirmed to fit, on its way to you quickly.
