hello;
.
please just answer ALL the questions that were already asked and the following. if you don't we can't help you other than to say buy a $200.00 electric fan and a $400.00 radiator.
he wants temp in traffic and at steady speeds above around 40.
forget about the switch as mentioned. it does NOT apply to your set up in any way shape or form.
does your vacuum diaphragm have one or two hoses going to it?
aluminum heads?
big cam or does it seem pretty mild?
if it is stock i would set timing to 8 degrees btdc.
if it has a slightly bigger than stock cam then 10.
if it is a massive cam, then 12.
if it turns over more slowly when it is hot then either your starter sucks or more likely you have too much initial timing.
use white out to put a line on your damper at 0.
put 1 dot on the 10 btdc mark.
put 2 dots on 20.
put 3 dots on 30.
put 4 dots on 40.
disconnect and plug the vacuum advance.
what is timing at idle
at around 1600 rpm or 1/4 throttle
open throttle 1/2 way and tell us what the timing is.
reconnect vacuum and with throttle 1/2 way open, tell us what timing is.
how wide is your rad?
how many rows deep?
exactly how thick is the core, not the top tank?
has this only done this in hot weather?
EXACTLY how hot does it get in degrees?
if you do not have a temp gauge how do you know for a fact it is getting hot?
what rating is your thermostat?
how many blades is your fan?
is it a clutch fan or fixed fan?
how far from the rad is it?
get it tested with an infra red gauge just behind the thermostat housing.
