64 Impala Engine Coolant Heating-up!
Trying to lower temps on my 64 Impala w/built-up bullet-proof 283. I have a standard 2-core radiator, shroud, fan and fan clutch. When cruising on a hot day the temps are in the 225 to 230 range with a 160 stat. I want to lower temps so maybe this will help others. First, changed the fan to a 19"- 6-blade steel, 36 deg type from the local speed shop. Got rid of the fan clutch and installed a spacer with the new fan. Also put in a cooling additive that racers use to eliminate hot air bubbles in the water jackets that attech themselves to surfaces internally. After driving the car about 50 miles on a hot day the temps actually dropped to stabalize at 220. Total cost was $74.00. Next I will add-on a crossflow radiator to drop it a bit more and will post the results here. Hope this to be helpful to others.
