The Chevelle Aluminum Radiator in Short

The CoolingSky 3 Row Aluminum Radiator for Chevy Chevelle provides a high-capacity solution with a 16 7/8″ H x 28 1/4″ W core. This specific core size ensures a significant increase in heat dissipation compared to standard single or double-row units.

Before You Buy: Chevelle Aluminum Radiator Checklist
The first thing to check is your vehicle’s model year and series to ensure the radiator is compatible with your specific engine bay layout.
- ✅ Confirm vehicle compatibility — 1973-1986 Chevy/GMC C/K C10 C20 C30 K10
- ✅ Measure available width — 33 3/4″ overall width
- ✅ Verify height clearance — 18 7/8″ overall height
- ✅ Check inlet and outlet sizes — 1 1/2″ diameter
- ✅ Confirm core dimensions — 16 7/8″ H x 28 1/4″ W
- ✅ Budget for professional installation — a qualified installer is required for all radiator mounting and plumbing.
You should not buy this radiator if your vehicle falls outside the 1973-1986 Chevy/GMC C/K series range, as the direct bolt-on OE fitment will not apply.
What the Numbers Mean in Use
Direct Bolt-On OE Fitment
The CoolingSky 3 Row Aluminum Radiator Kit for Chevy Chevelle offers direct bolt-on OE fitment for 1973-1986 Chevy/GMC C/K C10 C20 C30 K10 models. This means you can install the unit without modifying your vehicle’s mounting points or brackets, as the design matches original equipment specifications.
Because the Chevelle Aluminum Radiator matches these original dimensions, you avoid the risk of mounting mismatches that often require custom fabrication. Verify your specific year and model’s rail spacing before ordering to ensure a seamless installation by a qualified mechanic.
Dual Fan and Shroud Assembly
The Chevelle Aluminum Radiator includes two 12″ fans and an AA5052 aluminum shroud to manage airflow. To ensure these fans move enough air to prevent overheating, you should confirm you have sufficient clearance between the radiator face and the front grill.
The 12″ fan diameter determines the volume of air moved; if your engine produces high heat, ensure the radiator is positioned far enough forward to allow the fans to pull air without restriction. If the data for specific clearance is not provided for your unique engine bay, measure the gap between the radiator and the grill before purchasing.
AA5052 Aluminum Construction
The Chevelle Aluminum Radiator features a 3-row AA5052 aluminum core with a core size of 16 7/8″ H x 28 1/4″ W. A 3-row core provides significantly more surface area for heat dissipation than a standard 2-row radiator, offering higher cooling capacity for high-output engines or heavy-duty towing.
The AA5052 aluminum material provides a balance of weight and heat transfer efficiency. Because the core is 3 rows deep, you gain a larger volume of coolant processing capacity, which helps maintain stable operating temperatures during sustained high-load driving.

What Buyers Still Want to Know About the Chevelle Aluminum Radiator
Will the Chevelle Aluminum Radiator leak under high pressure?

Is the Chevelle Aluminum Radiator worth the cost for a standard build?
