Was the plastic water inlet tube in good shape? Thats the tube that houses the thermostat. Are you on original drums also?I hit 200k recently too, bought used at 63k. As part of my 200k preventative maintenance I replaced the radiator(original), upper and lower radiator insulators, radiator cap, both radiator hoses, thermostat, coolant, transmission filter, flushed 14 quarts of transmission fluid through the radiator connection, replaced both low and high beam bulbs(probably original), turn signal bulbs(original), rear brake shoes(original), and restored the headlight housings due to hazing. Also got a new spare tire and wheel. Then promptly went on a 1,400 mile road trip and it ran like a champ. On to 300k!

I had the water tube under the intake manifold leaking, it shorted out one of the anti-knock sensor. So I took that all apart, cleaned all of the intake tubes, replaced all of the gasket I could, like valve covers and such. Then I cut the little plastic piece in front of the air scoop to allow colder air to inter the air duct, LOLWas the plastic water inlet tube in good shape? Thats the tube that houses the thermostat.
