    On my '74, and on Landyacht's '66 Merc, I just used a one gallon coolant bottle. Babe has the '90 Town Car fan shroud, which has the factory bottle mounted to it.

    I have to ask, does the tube reach all the way to the bottom of the tank? Because otherwise it won't work as a recovery tank, only as an overflow.

    Yes, the plastic tube inserts to the bottom of the tank.

    Strangely enough, this '75 GT factory 460, came without a coolant overflow/recovery cap and tank and was very bad to boil over when stalled in traffic with the A/C running. Adding a recovery system and later a 3-core radiator solved all that.

    Yeaah, wait untill your trusted doctor tells you that you have the body of a 110 year old. Comes from burning the candle on both ends untill the middle is smoking too. Damn if it wasn't fun though !

    That's pretty good news for a 120 year-old!

    Despite mentally thinking I am still 25, I realized that the mileage on my 71 year old body was showing through when 40 year old's get up and offer me their train seat.:)

    Don't feel so bad. My neighbor volunteers at the assisted living home in the area helping with the "old" people there. In June she will be 103 and still living at home by herself.

    I can only hope I will be that healthy at 80 years old, let along 103!
    Reminds me of being on a flight from San Jose sitting next to a very nice lady going to Burbank to visit her son for her 100th BDay. Sharp as can be. She even tried to sell me her late husbands 1966 oldsmobile toronado.

    I have found that heater cores,with proper maintenance,will last a while.Just dont install a new carpet or back flush core...Failure will soon follow.

    Damn! Another heater core leak.
    I had switched the Cold Case 16 lb. cap to what I believe is a correct 13 lb. cap in March when I put the new core in. Just for fun, I put the core in a tub of water and blew in one tube with all my might while sealing the other with my thumb, and I didn't see any bubbles at all. I had installed brand new heater hoses in March, and found no cracks or pinholes in them. And I know I double-checked the hose clamps at the core, since this is a PIA job under the dash, and I didn't want any leaks there. I'm baffled...but I have a new aluminum core on the way, and I may go to a 9 lb. cap.

    Unless the cores you're buying are absolute junk, there's no reason to put lower pressure caps on, that just covers any other problems that don't stem from the core itself. Rather, once installed and inspected, put a pressure tester on and test the system at the 13 pound pressure. Also, check to see if you have stray voltage in the system. Connect a DMM negative lead to the battery NEG, and dip the tip of the positive probe in the coolant. A normal voltage at or below .2V is fine, but between .2 and .5 is a brewing problem, .5 and above is active electrolysis. If your system is at that point, inspect your block and cylinder head grounds, clean or replace anything appearing bad. If the electrolysis persists, add grounds, from cab to subframe, from radiator to core support, and from block to subframe.

    Most of the heater cores available these days ARE absolute junk - ask any guy at a radiator shop. :mad:

    Dunno about China, but GMC has been putting out some real schlock stuff in related fields (A/C evaporators and condensers). Check out the lawsuits (and my wife's Yukon).
