Question about 1992 Honda Prelude
Have a pressure test done on the coolant system and look for leaks at the rear of the engine and inside at the heater core. Check the sump oil for grey colour and if there is colour or moisture on the dip stick the leak may be from corrosion holes behind the water in the aluminium timing case housing.

Are you seeing an actual leak on the ground, or are you just having to add coolant ?

It is either a blown head gasket or a cracked head. Depending on which motor your civic has, this could be a tricky replacement, either way, you have to remove the head off of the motor, and then take the head to have it pressure checked to see if there is a crack in it. Nine times out of ten though, you can see a crack in the head with your eye, but you have to have the right "eye" to be able to see the crack.

for the water pump leaking, get some engine coolant stop leak from any automotive store, it usually contains pump seal lubricant also. the power surges are a separate problem from your pump leak.

Water pumps leak when they start going bad... it's kind of a warning sign before they let loose. So there's a good chance that you're right.

SOURCE: CAR OVERHEATS AT TIMES. I
reasons it overheats
1. bad waterpump(youve replaced it)
2. car is leaking coolant (youve changed hoses)
3. one or more hoses might collapse at the time of acceleration causing the flow of coolant to get cut off(this actually sounds possible because if you changed the water pump, it should create more suction force than the old one. also what can contribute are bad quality hoses, but usualy only the top radiator hose would be affected. putting those two together and the water pumps suction force collapses the top hose)
4. fans dont turn on(you said they did)
5. thermostat gets stuck(you also said it is a possibility)
6. air in the cooling system(you should bleed the cooling system through the thermostat)
these are the only reasons i can think of that can apply to why your car is over heating. one thing you should try is get the car to normal operating temperature, and once it starts to overheat, observe the fans(hood open of course), if the fans turn off after a couple of seconds even if the dash shows your car is over heating, then it is a good possibility that your tw sensor(sends temperature to dashboar) is bad. also, have someone accelerate the car while in park, and observe the lower hose, if it collapses, then there is your problem, if not then, you might have another problem. if you check these, then your thermostat getting stuck is a good possibility. the easiest way to test it, is simply to remove it and drive without it for a couple of days. since the thermostat housing is attached to the lower radiator house, u will spill some coolant so you should take this chance to bleed the air system. if you need help doing any of this or you have any other questions, just drop a comment and ill be glad to help, hope this helps, goodluck.
