Dear EditoR

Draining the antifreeze from your M113A2 carrier's thermostat

housing is a real problem.

There's no ±om to slip a pan under the housing²s straight

petcock, so when it's opened³ an´Ifreeze runs out all over the

engine.

µ¶ve come up with a way to

that. ·eplace the straight petcock

with a 90° draincock, NSN 4820-00¸293¹3669³ and hose adapter,

NSN 4730º00º555º1152.

Then» when you're ready to drain the housing³ attach a 5¼ to 6ºF

piece of rubber tubing³ NSN 4720¸00¸847½1710³ to the adapter and

open the drain valve. The antifreeze ¾ows through the hose and

stays o¿ the engine.

Make sure you drain the antifreeze into a suitable container and

dispose of it properlY thoughÀ
