Hi,

There are two rubber lines approx 1 inch diameter (about the size of heater hoses) that are below the intake mainfold that appear to have hardened. They have hose clips on each end instead of screw type hose clamps and run parallel to one another.

Are these special molded coolant hoses or other hoses that are made of harder rubber or is this hardening an indication that they need replacement. None of the other hoses in the engine compartment have devitalized in this manner.

Thanks
