Description

Detroit Diesel 23530452 EGR Cooler - Genuine Detroit Diesel EGR Cooler for Series 50 8.5L

The Detroit Diesel 23530452 is the square-type EGR cooler for the Series 50 8.5L. It runs hot recirculated exhaust through internal tubing surrounded by engine coolant, dropping the gas temperature before it re-enters the intake to cut combustion temps and NOx. Stainless welded construction with flanged gas connections, coolant fitting, and mounting bracket.

Verify fitment with us before ordering to ensure the correct part for your application.

Purpose of the Part

It's a heat exchanger between the exhaust and the cooling system. Hot EGR gas passes through the tubes, engine coolant flows around them, and the gas comes out cool enough to recirculate without spiking combustion temps. When the internal tubes crack, the two sides mix - coolant into the exhaust or exhaust into the coolant - which is where the real trouble starts.

Issue Symptoms / When to Replace

- Coolant loss with no visible external leak - the classic internal cooler crack
- White exhaust smoke and a sweet coolant smell
- Coolant surge tank pressurizing or pushing coolant out - exhaust gas leaking into the cooling system
- Overheating or low-coolant warnings
- Soot or sludge in the coolant

Brand Information

Detroit Diesel built the Series 50 as the four-cylinder companion to the Series 60, and a genuine 23530452 cooler is made to the pressure and thermal-cycling demands that make EGR coolers fail - correct tube construction, welds, and flange fit for that engine. Detroit Diesel, a Daimler Trucks North America company, builds engines, emissions components, and drivetrain parts for heavy-duty applications.

Installation Notes

- New gaskets on both flanges, torque to spec.
- If the old cooler failed internally, flush the cooling system and check for coolant contamination before running the new one - exhaust soot and oil in the coolant will foul a fresh cooler. Sort out why it failed, don't just swap it.
- Pressure-test after install to confirm the joints and the new cooler hold.

How to Identify an OEM Part

- Look for the Detroit Diesel emblem stamped on the shell.
- Find 23530452 stamped on the end tank and match it to your listing.
