Dayco Radiator Editorial Review
The Dayco 72403 Lower Radiator Hose has garnered mixed responses from customers. Many users note a perfect fit for their vehicles, particularly praising the product’s quality. Several reviews highlight satisfying experiences with the hose's performance, suggesting reliability after installation. However, some users have reported significant sizing issues, particularly ASE-certified technicians who have faced challenges with the hose’s fit. One reviewer recounted the difficulty of fitting the hose onto the radiator due to an abnormally small diameter, while the other end was oversized, leading to a pinch when clamped and subsequent leakage. Despite these drawbacks, some customers have managed to work around the sizing discrepancies, customizing the hose by trimming it to achieve a proper fit, which has led to effective performance afterward. Overall, while the Dayco 72403 has a firm base of satisfied users, potential buyers should be mindful of the sizing issues reported by some. **
