    4.9 liter--replacing heater core "hoses".

    I want to replace the 2 original heater core "hoses" on my '95 Sedan Deville 4.9 liter.These look like a real PITA to get at.My local mechanic has this job listed at 2 hours labor.
    I`d appreciate any recommendations on how to get at them properly.Hopefully someone here has replaced these before and can offer some helpful tips.
    Thank you.

    What's wrong with those hoses? Just tighten up the clamps and that's it.

    The 2 hoses are original (13 years old),are beginning to bulge and could spring a leak at anytime.I`d rather replace them before they rupture and prevent a tow.During the past 2 years i have replaced all the original hoses under the hood with new ones,except for these 2 heater core hoses.

    The task is nearly impossible without this tool.....http://www.tooltopia.com/index.asp?P...OD&ProdID=7131 also suggest you order the hoses from the dealership,as the aftermaket hoses do not fit correctly.

    Thanks for the info----i ordered the 2 hoses from the Caddy dealership before i even posted this thread.I know for hoses that are preformed as these 2 are,it`s always best to get them at the dealership even though they are a bit pricier.They wanted $19.00 for the hose closest to the firewall and $31.00 for the other one.
    I have decide to get them installed at my local trusted Meineke service center since one of the hose clamps has to be loosened from underneath the vehicle.They`ve done this type of job before and have the proper tools.After 13 years,these hoses are more than likely fused to the heater core outlets and the hoses will probably have to be cut off.
    I sure long for the good ole days when cars had plenty of room under the hood for a do it yourselfer to be able to work on the engine alone.These days it`s a knuckle busting chore,needing special tools for the bizarre angles involved,not to mention having to be a contortionist also.
