I never even knew it was a "heat shield" if you are talking about the
plastic box that went over the top. I threw mine away when I had to replace
my stock battery that left me stranded one day.

It is a group 27 battery. The heat shield may have to be removed or modified
if not using the OE battery. On my old 98 I used a Deka group 27 and tossed
the heat shield. 4 years and nearly 100K miles later, that same battery was
still in the truck when I traded it in.
YMMV,

Is there a standard case size for the HD battery in the '98 318 ? I think
it is close to a "Group 27" but I want to make sure that the heat shield
still fits and allows access to the terminals. I'm in a small town (Willits,
CA) now, and everything is 90 minutes away in Santa Rosa, or 2 days shipping
for the local auto parts store.
Symptoms. Engine stalling, with code P1594 - alternator overvoltage &
computer shutdown.
First thought was fuel pump, but I finally got a code, by not switching off,
and driving into the shop. I've got 160,000 miles on the factory
alternator, and the regulator is built into the ECM. So a thought is that
the 6 year old battery is not regulating the charging right ?? and it's
cheaper to replace an old battery that may die any week, instead of the
computer. Any thoughts if worn brushes on the alternator could cause this?
(poor contact , full charge called for, then good contact and overvoltage
before the computer can roll back the charge rate ?
Or maybe the battery temperature sensor sitting in a puddle of battery acid
under the battery has gone bad, calling for odd charge voltage ?
