The Koyo HH652890N radiator is designed to fit select 2005–2011 Lotus Elise and Lotus Exige models equipped with the 1.8L inline-four engine and manual transmission. Its N-FLO triple-pass design supports efficient coolant circulation and heat transfer, helping maintain stable engine operating temperatures during everyday driving and demanding road use. This automotive radiator is intended for applications matching the listed vehicle and transmission requirements.
Koyo builds the HH652890N with a performance-focused cooling design that promotes consistent thermal management. The triple-pass configuration directs coolant through the radiator core multiple times, increasing cooling efficiency within the available installation area. This makes the radiator a practical choice for replacing a worn or damaged unit or upgrading cooling performance on a compatible Lotus application without suggesting manufacturer endorsement or affiliation.
