Dorman Engine Coolant Crossover Pipe — Aluminium Direct-Fit Replacement for Select Chrysler Dodge Jeep Ram VW Models — 902-3102HP

The Dorman 902-3102HP is a direct-fit engine coolant crossover pipe redesigned in durable aluminum to replace cracked or leaking plastic originals.

This OE FIX replacement restores coolant flow between engine components while matching the original pipe’s routing and mounting points. Dorman upgraded the material from plastic to aluminum to offer improved heat tolerance and resistance to the common failure modes that affect plastic crossover pipes. Before buying, confirm vehicle compatibility by entering your make, model and trim into the garage tool to ensure proper fit.

Will this crossover pipe fit my vehicle?

The Dorman 902-3102HP is manufactured to match the original equipment’s dimensions and mounting locations for specific Chrysler, Dodge, Jeep, Ram and Volkswagen Routan model years. Fitment depends on engine and trim, so verifying your exact vehicle is required. Using the garage tool or fitment guide prevents returns and ensures the replacement aligns with factory hose connections.

• Compatible with many Chrysler 200/300 and Dodge Challenger/Charger years listed by Dorman
• Fits select Jeep Cherokee and Grand Cherokee models and multiple Ram and ProMaster years
• Also compatible with Volkswagen Routan model years indicated
• Always confirm fit with your vehicle’s year and trim before purchase

How does the aluminum design improve durability?

Dorman replaced the original plastic construction with aluminum to combat the most common issues: cracking, warping and pressure-driven leaks. Aluminum better resists high underhood temperatures and chemical exposure from coolant, reducing the chance of failure over time. The part undergoes try-on and material testing to validate long-term reliability and proper mating with factory hoses and clamps.

• Aluminum resists heat-related deformation better than plastic
• Lower susceptibility to impact cracking and stress fractures
• Tested for fit and compatibility with original mounting points
• Designed for OEM-style hose connections and clamps

What should I expect during installation?

Installation follows the same routing and fastener locations as the original OE pipe, so mechanics and experienced DIYers can usually replace it without modifications. You’ll need basic hand tools, coolant catch pan, and new hose clamps if the originals are worn. Always drain the cooling system to below the pipe level, replace any worn hoses, and refill and bleed the system according to manufacturer procedure.

• Direct-fit design avoids cutting or adapting hoses
• Standard hand tools required; mechanic-level accessibility depends on vehicle model
• Recommended to replace worn clamps and hoses during installation
• Refill and properly bleed the cooling system after replacement

How does this part compare to OEM and aftermarket alternatives?

Dorman’s OE FIX approach aims to replicate original fit while improving material performance where factory plastic parts have shown weakness. Compared with identical-plastic aftermarket replacements, the aluminum pipe offers better longevity and reduced leak risk. It’s designed to meet or exceed the functional expectations of the original component without requiring custom modifications to the vehicle.

• Matches original routing and mounting for straightforward replacement
• Aluminum offers enhanced resistance to heat and cracking versus plastic
• Quality-tested to ensure consistent fit and function
• Backed by Dorman’s OE FIX replacement program credentials

Who is this for: The Dorman 902-3102HP is aimed at vehicle owners and technicians replacing a failed or aging plastic coolant crossover pipe on compatible Chrysler, Dodge, Jeep, Ram or Volkswagen Routan models. It’s suited to repair shops seeking a reliable OE-style alternative and DIYers who want a robust, direct-fit replacement that reduces future leak and crack risks. Confirm vehicle fitment before purchase to ensure correct application.
