    Comments about CARQUEST by Dayco Molded Heater Hose:

    I assume that this product fits Chevy Vans that ARE NOT equipped with rear heater systems because it most certainly was not the correct hose for the 97 Oldsmobile Silhouette (3.4L) I bought it for. Luckily all I really needed was the quick connect fitting so I was able to re-use the original hose off of the van I was working on and attach it to the fitting, but had I needed the molded hose also then this item would have been completely useless.
