Caterpillar EGR Coolers
Caterpillar EGR coolers are critical components of the diesel emissions system, designed to reduce the temperature of exhaust gases before they are recirculated back into the intake system. By cooling exhaust gases, the EGR cooler helps control NOx emissions while maintaining stable combustion and engine performance. At Advanced Truck Parts, we supply replacement EGR coolers for Caterpillar engines including C13, C15, and C16 platforms.

Caterpillar EGR Coolers by Engine Platform
Caterpillar ACERT engines use EGR systems that rely on high‑efficiency coolers to reduce exhaust gas temperatures before recirculation. Proper EGR cooler operation protects engine components and helps maintain emissions compliance.
Caterpillar C15 EGR Coolers
The Caterpillar C15 ACERT engine uses an EGR cooler to lower exhaust gas temperatures before gases return to the intake system. These coolers operate under high thermal stress and can eventually fail due to soot buildup or internal cracking.
- Caterpillar C15 ACERT engines
- Caterpillar C15 on‑highway truck applications
- Caterpillar C15 vocational and heavy‑duty platforms
A failing C15 EGR cooler may cause coolant loss, white exhaust smoke, or emissions system fault codes.
Caterpillar C13 EGR Coolers
The Caterpillar C13 engine also uses ACERT emissions technology with an integrated EGR cooler system designed to regulate exhaust gas temperatures and maintain efficient combustion.
- Caterpillar C13 ACERT engines
- Caterpillar C13 truck applications
Proper EGR cooler operation helps prevent overheating and protects other emissions system components.
Caterpillar C16 EGR Coolers
The Caterpillar C16 engine is used in high‑horsepower and heavy‑duty applications. Its EGR system relies on a durable cooler to manage high exhaust temperatures under heavy load conditions.
- Caterpillar C16 heavy‑duty engines
- Caterpillar C16 vocational and industrial equipment
Common Caterpillar EGR Cooler Failure Symptoms
- Coolant loss without visible leaks
- White exhaust smoke
- Overheating issues
- EGR or emissions system fault codes
- Exhaust gas contamination in the cooling system
EGR cooler failures can impact both engine cooling and emissions system performance, so early diagnosis and replacement are recommended.
Verify Fitment Before You Buy
Caterpillar EGR coolers must match the engine model and emissions configuration. To confirm compatibility before ordering, provide:
- Engine Serial Number
- Truck or equipment year / make / model
- Engine model (C13, C15, C16)
- Current EGR cooler part number
This information allows our team to confirm the correct EGR cooler for your Caterpillar engine.
