Temp At 220+

Alarus · Jun 22, 2005

I was on my way home earlyer today and noticed that my temp was above 220, the first time i had the car off for a few min and then got back in it and noticed that the temp was up there, so i started it and it went down to about 190 witch is normal, but then on the way home the temp went back up (this was after a mountin, so i dont know if it went up going up the mountain or what, but i had it in nutral going down hill when i noticed it.

Could this prob. be the a/f mix, my dad and i went out and adjusted the dwell and then he started messing with the mix screws leaning it out, so thats why im thinking it might be that, i had a RC car that if you had it to lean it would over heat and seise up.

The screws you speak of only adjust the idle mixture A/F. They won't do anything for except for at idle, and just before tip in of the main jetting system. If it always cruises around 190, and only does this going up the hill, it would seem a more efficeint cooling system would be in order.

well it was pretty damn hot and going up a hill is more of "load" or strain,so the extra heat sounds normal

Totally not true.
The air/fuel mixture screws do exactally as they sound , adjusts the ratio of air to fuel. If they're adjusted too lean your car will run too hot, you can even melt pistons.

Cooling tips (even in Arizona):
Run the biggest radiator you can fit (alum. cross flow)
Run the highest Lbs. radiator cap your radiator will allow.
The biggest, highest flowing electric fan you can find.
160 or 180 thermostat
Stewart Components water pump (flows 40% more than stock)
Overdrive water pump on a street car. (upper pulley is smaller than the lower)
Proper timing and proper air/fuel mixture are also important.

Oh Boy.................10secgoal is 100% correct

10secgoal · Jun 23, 2005

DOH! That has to sting. Oh well. I don't sell tires..maybe I should sell carbs.
Alarus, I think at most all you need is a good aluminum rad. Even with a stock pump, fan, and everything else, it should easily hold your 190 deg you want. Your not cooling a nascar in AZ. The summit cheapy rad is really a Northern. I put that on and ran 160 dead on in 29 palms. It gets hot there too. 115 deg...still at 160, and this was not a stock motor, basically what I have now, but had RPM heads and not the ones I run now.

My Bad!
sorry, 10secgoal was absolutley correct and I was wrong. I apologize.
The air/fuel mixture screws effect the idle circuit only.
Thanks hueypilot for correcting me

When you adjust the dwell, you also effect the timing. Given that the car started overheating the same day that you did the adjustment, that's most likely the problem.

No worries Grego

Also, you may want to look at an external oil cooler....made a big difference on my 67-

Same here!

Alarus · Jun 24, 2005

well so you know i adjusted the a/f ratio and took it out, didnt go over 195, got it up to about 85mph (have a long starit not traveled by others) and cept it there for a few sec, still never overheated. got the temp down even more yesterday by adjusting the timing.
