THeres no need to drain the whole system every time you need to replace a bit of cooling system--just place a bucket underneath where your working-leave coolant tank lid on & undo the bit you are replacing-ie the thermostat--undo 4 bolts on plastic housing-assumme yours is after '86--let the water come out(not much if I remember rightly)--replace 'stat & O ring--careful of that plastic bleed screw it breaks easily--filter coolant thru stocking & pour back in coolant tank(fill to brim)--start up with bleed screw open on stat(not essential if siezed--loosen bleed screw on rad-coolant should stream out with no bubbles-tighten-both screws-with engine running--job done--
