Spitted ones,
There have several posts lately regarding Spits that are
overheating or running hot.
My '73 1500 had this problem for many years, and I spent
a lot of time and money trying to cure it. Let me tell
you what I did to finally reduce the operating temps.
Note: my temp gauge is a dual oil and temp gauge from
another LBC that will remain nameless. The only time
the temp goes past midway is when I shut the engine off
or spend an excessive amount of time stopped in traffic.
(Excessive = more than 30 minutes.) And even then, it
doesn't go past about 60% of the scale.
What I did:
1. Replaced the original narrow radiator with a full
width one from a later car. ISTR that the difference is
something like 6 inches in width. That is the US spec
22 inch rad.
2. Keep the engine degreased/clean. You would not believe
how good an insulator oil and grease is.
3. The last thing, I cannot prove it conclusively, but does
work for me. The last time I flushed the cooling system,
I used a propylene glycol based antifreeze instead of
ethylene glycol based. (Sierra Brand).
Hope this helps,
Doug
