Engine Cooling problem
1992 Honda Accord 4 cyl Front Wheel Drive Automatic 145000 miles

My 92 Honda accord overheats intermitently. I have replaced the thermostat. New thermostat purchased from CARQUEST. Problem did not go away. On the Highway temp guage shows normal temperature.
When slowiing down temp gauage needle rises towards very high end. Radiator Fan may not be kicking in. I have also replaced Fan Switching SENSER
( A-93) 021. Purchased from Honda. Problem still persists. Car radiator, waterpump, hoses were replaced two years back. Please Help.

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: , Pressure test the Rad. Cap, Clogged radiator, air lock in the cooling system, Fan clutch, Radiator electrical fan, collaspe hoses, water pump.
