Most likely lack of air flow. This is common wiht a re-cored
radiator where they used a core with too many fins too close together, so
it restricts air flow at road speed. For that you need a really
large fan, or an electric fan to assist the air push. Better to get
back to an original type radiator with more air flow capacity.<br class=""><br class="">
Other possible causes may be a loose fan belt (slippage reducing fan
speed), or a loose or missing impellor on the weter pump, or a clogged
radiator core restricting water flow. Possibly a faulty thermostat
that does not open all the way.<br class=""><br class="">
