Why is my engine only overheating at high speeds?

Asked by Jkgriffiths2007 Jan 01, 2020 at 06:22 PM about the 1999 Honda CR-V LX

Question type: Maintenance & Repair

Engine overheats ONLY at high speed. Idling, stop
and go driving temp is norm. New thermostat n
new radiator, radiator fan works still over heats.
Block tested, head gasket NOT blown. Haven't
changed water pump or temp sensor yet. Could
these be it?
The WP is enclosed with the timing belt, so not a
quick fix.

Might be the water pump. If the fins are eroded you would not get enough water flow.
