Re: Packard model 2365, 288 cubic inch engine running hot

Thank you. These are great inputs!
Actually, the engine runs hotter at idle with the hood on then when it is off.
That is why I am thinking it is a circulation problem.

I was planning to go to a 140 degree thermostat. I have a 160 in there now. I realize that it is not smart to remove the thermostat completely since you need heat in the engine to remove impurities from the oil, etc.

I already had the radiator cleaned well so I appreciate your comments on not doing the forced aggressive flush but instead using the acid flush a few more times.

I like the idea of a fan shroud. Do I have to make that custom? Or do you think I can buy one from a later model?
