<![CDATA[chevy 350 getting to hot]]>Well my 86 3/4 ton 350sb has been running pretty warm since i got it.. So i replaced the waterpump, tryed another radiator,bypassed the heatercore(might be blocking coolent flow?) changed the thermostat from a 195 deg to a 160 deg.. And with the 160 it runs realy cool for a while but still gets warm after a bit of driving about to 230 deg.. Also when i come up to a stop light and the temp is at say, 215 deg it cools right down to about 190.. But when i take off its right back up to 215-220 befor im across the street.. I do have an aftermarket temp gauge along side my stocker to see if the stock gauge was just messed up... So iv done about everything i can think of... OH and there is no coolent in the oil or anything

there should be way more than adequate airflow across the rad. even if the fan was taken off, when traveling down the highway

Make sure you have the right fan, s-10 fans and water pumps will bolt right up but have opposite rotation. Also make sure there's no restriction in the exhaust.
