Coolant hose / Trans fluid replacement V70-XC70

posted by  someone claiming to be kcarl on  Sun Jan 1 10:26 CST 2006 [RELATED]

My '98 NA V70 has about 118K miles on it, so I figure it's about time to replace the coolant hoses (I've replaced the coolant once, but hoses are original). I checked the parts list at FPC Groton and came up with the list below

Upper radiator hose
Lower radiator hose
Heater inlet hose
Heater outlet hose
Thermostat / gasket
New hose clamps

THey also listed the following parts that may or may not be needed? Can anyone comment on whether these parts, or anything additional might be needed? ALso, can anyone refresh my memory on acceptable coolant types?

Expansion tank hose
Heater O-ring kit


In addition, I am considering flushing the transmission. I've done this once before a few years ago, but I didn't replace any seals, O-rings, or clamps on the transmission fluid line. Should I this time?


Thanks,
Kcarl

    It sounds a little premature to swap all of the coolant hoses, but that is your call. I would spend the extra 10 bucks and get Volvo coolant.
    While at volvo parts, get a new clamp and O ring for the tranny fluid flush, the old clamp is probably rusted by now.
    Forget the expansion tank hose, unless it starts to leak. And if you are going to replace the heater hoses, then get the O rings (that is a weak point).

      It sounds like most responses feel that 118,000 miles is too soon for changing hoses. Anyone know the recommended mileage / age for changing hoses?

      Thanks again,

        It really depends on the climate and age of the car rather than the miles. Hot climate + 15 years sounds good to me. One of the indicators is a soft radiator hose (top) when the engine is cold. Soft meaning very easy to squeeze.
        The tranny fluid needs to be changed every 25K miles. That should keep you busy for an hour!

    If there is reason to replace all of these hoses, go for it. However, you won't need the "O" ring gasket for the thermostat. The thermostat that Groton sells comes with one, and in my opinion, it's much better than the one you buy by itself. I bought the thermostat and extra "O" ring gasket from them by accident a few months ago not knowing that the thermostat came with one. I was not impressed with the quality of the one bought on its own. Buy the 87degree thermostat instead of the 90degree one. It will warm your car up and you will feel more heat in the cabin then the higher degee one and there are no adverse effects to using it in the summer either. Just my $.02

    There are no replaceable part in your transmission that I know of without tearing it apart. Just flush your fluid like explained in Bay13 with a machine or on your own as IPD explains on their site (http://www.ipdusa.com/pdf/PI-290TrannyFlushKit.pdf). If you really want to upgrade your transmission lines you could put in the magnafine filters that IPD sells (http://www.ipdusa.com/ProductsCat.aspx?CategoryID=386&NodeID=277&RootID=629) ...magnetic parts pick up any loose microscopic metalic particles, but I've never done it and don't feel it's really necessary.

      Coolant hose / Trans fluid replacement V70-XC70

      posted by  someone claiming to be kcarl on  Mon Jan 2 03:20 CST 2006 [RELATED]

      I am considering replacing the hoses as preventative maintenance. I wasn't sure how long they normally last. At a minimum, I feel I do need to flush the coolant. Anyone which coolant types are acceptable?

      Thanks for the info,

      Kcarl

        You can use any with ethelglycol (spell?)...Peak is a good brand. It is the green/yellow flourescent stuff. Go to your Autozone or Pepboys and make sure the label on the jug says "for any radiator." I bought the stuff already mixed with water, but you don't have to do that (more expensive). Avoid the radiator cock (easy to break off)...there's another outlet on the low side of the engine. Open it up and flush good, then close the cock and empty all but a quart or so of the 100% coolant (1 Gal) jug, then fill the rest of the way with distilled water. Drive it and the coolant level will settle after air bubbles make their way up to the expansion tank...top off with more distilled water and you're good to go. Try to avoid tap water unless you want to run a hose in just to flush out...but in that case, for the last flush use distilled water before adding coolant again. Distilled water is very cheap...less than $.60 at Kroger for a gallon jug.
