[Shotimes] Radiator Hints for Gen 2 ATX

I swapped a radiator in a Gen 2 ATX today.  There are a lot more steps than there
are for an MTX car.  I found two shortcuts that I bet aren't mentioned in any
manuals, including Helms.  I just thought I'd toss them out for your information, if
anyone is about to change their ATX radiators.   (The basic difficulties throughout
the procedure occur because the engine is closer to the front of the car than in an
MTX.)

With every ATX car, the hydraulic lines going into the cooling tank are a pain in
the neck.  This car is no different.  The top line isn't too hard to deal with,
after the bracket that holds parts of the wiring harness that crosses the top of the
radiator support is moved.  That top line has a rubber section just adjacent to the
connector, which makes it very easy to line up, and easy to remove also, since there
is no constant tension put on the connector by a slightly cocked metal line.  The
bottom connector, by far the harder to reach, is all metal, and was very hard to
remove, until I found the secret.  Before trying to remove the bottom connector,
remove the two small screws that hold the lines to the bottom of the radiator, where
they cross the front of the car from driver's side to pax side.  This will allow you
to move the lines as necessary to take tension off the lower connector, and remove
it with your hand.  I was able to reinstall it this way, and it took 1 minute or
less to completely fasten it, where it took about 5 minutes of working the hex nut
one face at a time to remove it, while there was tension on the connector.

You have to remove the alternator to get room for the right side tank to get past
it.  But you don't have to remove it from the car.  If you unplug the top plug, then
take the 4 bolts out, you can just set it back towards the waterpump (you've removed
the battery tray, so it will sit on the inner fender), where it will sit, and then
you can continue with the radiator.  That saves a lot of hassle removing the main
high-amp output wire with its connector underneath the rubber cover.  You do have to
remove the front upper idler pulley to get to the rearward alternator bolt.  I sure
wish MTX alternators were as easy to remove as ATXs.....that is one definite
improvement.

A couple of comments regarding the radiator hoses.  I used the aftermarket indicated
replacement hose for the upper hose, and the NAPA 7311 hose for the lower hose.  
Someone mentioned recently that the 7311 wasn't quite shaped the same, and rubbed on
something which might hurt it.  I could find nothing sharp that was in the vicinity
of the hose, although it did rub on another smaller hose....I believe it was one of
the ATX cooling lines.  There wasn't enough tension on the hose from the line to
cause it any damage.  The upper hose needed to be cut off by about 2 inches at the
radiator end.  I found that the inner rear corner of the ABS computer mounting
bracket tended to want to press against the hose in one particular place, which
might make a hole over time.  So I slit the piece of hose I cut off, and just
slipped it over the installed hose next to the computer, and that took care of the
potential damage.

Hope these hints work for you.

Later....

have a new one....just lazy!
