Hey folks just thought I would ask and see if anybody knows the answer. Where is the best place to take infrared temperature readings on a Chrysler 280hp 400 cubic inch inboard.
Also are there any parts of the engine where I would see really high temps like over 220F
Thanks jaso

Re: How to take infrared temperatures
Around the temp sender and thermostat are good places . But checking all over where the cooling system flow is a good idea . Other then the exhust manifolds near the ports you should not see 220 .

Re: How to take infrared temperatures
Thank you
I cant get over how helpful and supportive this forum is.
I believe pieces of an old impeller are stuck inside somewhere. I have changed impellers and am about to embark on checking the thermostat area and any small 90 degree elbow after the impeller.

Re: How to take infrared temperatures
If you think you might have impeller pieces stuck, it sometimes works to back flush the lines with a hose. That will often get the missing pieces out, but the only way to insure you have them all is to visually inspect.
