Best Place for temp strip

10 posts in this topic

I know that when the coolant is over 250 degrees F you are too hot but what about the temp for the side of the head. Im trying to determine the best place to put my new temp strip, or better yet most accurate place, so that I can visually see motor temps. I thought I saw a thread on the most accurate place a while back but could not find it today. Thanks:worthy:

Either the side of the head or one of the upper radiator tanks. BTW, assuming you use a 50/50 mix of common EG coolant and water with a 16 lb (1.1 bar) cap, 250 (℉) isn't actually too hot, but it's getting close. At 3000 feet or less, that should boil at 265, so "too hot" is at that point. Still, it's prudent to stop heating it up at 260 or sooner.

Six of one, half-dozen of the other. In that regard, there's little difference between ethylene glycol based coolants such as Coolanol and propylene glycol coolants like Engine Ice. In fact there's not much of a distinction between them at all, as far as how or how well they work when fresh.

EG coolant is extremely toxic, PG coolants are considered non-toxic (don't drink any).

PG coolants oxidize more rapidly, which forms lactic acid, and it can be very corrosive. All quality PG products include additives to protect the system from this, but it should still be changed out annually at the least just to be safe.

Neither is a really good lubricant, but both are better than plain water on that score.

Is there a company that makes a radiator cap with less pressure? I run Evans cooling system coolant and it boils a 385 with no pressure. Was curious if anyone made one.
