Description

Part #: WCF100433-IBB

The WCFab 2017-2019 L5P Duramax 2500 / 3500 & 2019+ L5D Duramax 4500 / 5500 / 6500 Fabricated Aluminum Coolant Tank Kit, mounts in OEM coolant tank location. The stock coolant reservoirs on these trucks are known to become cloudy and yellow with age becoming an eyesore when you're cleaning up the rest of your engine bay. More importantly, the stock units are notorious for the non-replaceable sensors that tend to fail prematurely causing a false low coolant warning. To fix the light on your dash using stock parts, you'll need to purchase and install a whole new coolant reservoir assembly...every time the sensor has an issue. To help clean up the under hood appearance of your truck and address this known failure point, our custom fabricated aluminum tanks include a high quality, cost effective float-type sensor that is easily serviceable for the life of your vehicle. - - Replaces the following GM Part Numbers: 84257137, 84214124, 84138913, 84257137, 84174037

Wehrli Custom Fab Coolant Tank, OEM Placement, for 17-19 Duramax L5P, Illusion Blueberry

MIA's Description

The Stage 2 upgrade for the 2017-2019 L5P 6.6L Duramax equipped Chevrolet Silverado or GMC Sierra 2500 / 3500 truck combines our Stage 1 High Flow Bundle and Stage 2 Intake Kit into a single package providing increased airflow for your turbo and engine for improved efficiency, throttle response, and turbo spool up. Eliminates weak points in the factory design that can contribute to lost power, boost leaks, and complete failures in hard working and high performance applications. Our high flow fabricated intake pipe, intake horn, and air box enclosure with dry filter assembly replaces the restrictive plastic factory parts on 2017-2019 L5P Duramax Diesel for improved engine performance and sound. Our Stage 2 kit also upgrades the restricted 2-piece, resonator equipped, 2.5 in. diameter driver (Hot) side intercooler pipe and leak-prone 2-piece plastic / rubber passenger (Cold) side pipe with WCFab's heavy duty 3 in. diameter 1-piece Driver (Hot) Side and 3.5 in. diameter Passenger (Cold) Side L5P Intercooler Pipes. Full assembly finished in your choice of WCFab’s signature custom powder coat colors for a look as unique as your truck. Installs with basic hand tools. Compatible with stock trucks, no tuning required.
