Will these HVAC parts fit my specific year Peterbilt 387?
Most of our heat and AC parts are compatible with Peterbilt 387 models from 2000 to 2010. However, there were minor changes in HVAC systems between early models (2000-2004) and later models (2005-2010), particularly in blower motor mounting and control panel configurations. Always check the product description for specific year compatibility, or contact our support team with your VIN number for exact fitment verification.
What are the most common signs that my heater core or evaporator needs replacement?
Key indicators include a sweet antifreeze smell inside the cab (heater core), foggy windows that won't clear, wet passenger floor mats, reduced heating or cooling performance, and visible coolant leaks under the dash. For evaporators, watch for weak airflow, warm air from AC vents, or excessive cycling of the compressor. These components typically last 8-12 years depending on maintenance and operating conditions.
Can I install these HVAC components myself, or do I need a professional?
Basic components like blower motors, resistors, and control switches can typically be installed with standard tools in 30-90 minutes. However, heater cores and evaporators require dashboard removal and can take 4-8 hours even for experienced mechanics. These jobs also require proper coolant drainage and refrigerant recovery equipment. We recommend professional installation for major components to avoid damage and ensure proper operation.
What's the difference between OEM and aftermarket HVAC parts for my 387?
OEM parts guarantee exact fit and original specifications but cost 40-60% more. Quality aftermarket parts from brands like Red Dot, Bergstrom, and Four Seasons offer comparable performance at lower prices. Aftermarket blower motors may have slightly different amp draws, and some heater cores use aluminum instead of brass/copper. All our aftermarket options meet or exceed OEM cooling capacity and come with warranties ranging from 1-2 years.
Why is my new blower motor making noise or not working at all speeds?
Noisy operation often indicates incorrect installation, debris in the housing, or a mismatched blower wheel. Ensure the motor is properly seated and the wheel spins freely. If the motor only works on high speed, the blower resistor likely needs replacement too. For variable speed issues, check the control module and wiring harness connections. Using a motor with incorrect specifications (RPM or amp draw) can cause premature failure and void warranties.
