This Aluminum Radiator is designed to provide maximum cooling efficiency to prevent premature engine failure. Its light-weight, and high-heat transferring aluminum features a tube and fin design that, dramatically increases surface area that enables the heat to dissipate more efficiently. This Aluminum Radiator is at least 40% more efficient than stock ones. Most importantly, it has a much higher capacity for coolant than stock ones, which means that your cooling system will be more efficient and will be more resistant to temperature surges in racing applications.<br><br>Core Dimensions: 18 1/2 x 20 <br>Overall Dimensions: 20 1/2 x 24 3/4 <br>Hose Locations: IN-PASS /OUT-DRIVER <br>Core Thickness: 2<br>Tanks: 2 1/2<br>Rows: 2<br>Tank Construction: Aluminum<br>Core Construction: Aluminum<br>Inlet Diameter: 1 1/2<br>Outlet Diameter: 1 1/2<br>TOC: NA, For AUTO use (<a href="/product.asp?part_id=221617" target="_blank">External Cooler</a>) <br>EOC: NA <br>Mount: Pin Mount<br><br><font class="HiliteFONT">Suggested Add-Ons:</font><br>Radiator Cap (<a href="http://www.radiatorexpress.com/product.asp?part_id=221633" target="_blank">SKU 221633</a>) <br>Thermostat Relay Kit (<a href="http://www.radiatorexpress.com/product.asp?part_id=221453" target="_blank">SKU 221453</a>) <br>Overflow Tank (<a href="http://www.radiatorexpress.com/category.asp?cat_id=R023" target="_blank">See Category</a>)<br>One 16" fan recommended for this core size (<a href="http://www.radiatorexpress.com/product.asp?part_id=221446" target="_blank">SKU 221446</a>)<br>Electric Fan Shroud Kits (<a href="http://www.radiatorexpress.com/category.asp?cat_id=R024" target="_blank">See Category</a>) for alternate mounting of fans<br>
