Alternatively, optimal GNSS code processing accuracy is possible with the Trimble DeltaPhase technology using a GeoXM™, GeoXT™ or Juno® series handheld, or a ProXT™ receiver. Decimetre accuracy can be achieved with the GPS Pathfinder ProXH™ and ProXRT receivers or the GeoXH™ handheld, which incorporates Trimble H-Star™ technology. Post processing with the GPS Pathfinder Office significantly improves the autonomous accuracy of data collected in the field all the way down to decimetre (10 cm / 4 inch) level, depending on the environment and the GNSS receiver.
I can get one and see if it helps, but before doing that I'd like to get some opinions on whether from what I describe it seems reasonable the o ring is the cause, or if in fact it seems likely this is indeed the water pump leaking.The Trimble® GPS Pathfinder® Office software is a powerful software package of GNSS post processing tools incorporating Trimble® DeltaPhase™ differential correction technology, designed to develop GIS information that is consistent, reliable, and accurate from GNSS data collected in the field. This particular o ring is not one available at local auto parts stores, but instead really is a Honda part which I would need to acquire from Honda. On removal and close inspection of the o ring on the water pump end of the inlet pipe, its really hard to say for sure whether it might be have some wear or imperfection that is allowing the leakage I described. The o ring on the other end of the pipe, which is identical but which fits into the thermostat housing, looks slighty nicer, but actually not much different.
I removed the inlet pipe and inspected the o ring but it does not necessarily look bad to the naked eye, not obviously deterioated or cracked or torn. Here's a diagram which shows the o ring I'm talking about, part number 19 in the diagram: Honda Automotive Parts I was wondering about the possibility it is the o ring on the inlet pipe on the water pump end that might be bad and could the source of this leaking.
I really don't want to go to the trouble to change the water pump if the water pump isn't the problem, because that entails having to remove the timing belt. Also, it must leak out pretty bad when driving, as if I fill the cooling system then drive to work one day or whatever then check it later it's really low or close to empty again. I can fill the cooling system up with coolant and like I said there's no visible leaking occuring until I take release pressure by doing something like loosen the radiator cap, then it leaks badly out of the area I mentioned. The engine surges on the car when it's cold, but as soon as the engine warms up the surging stops. Assuming it might be the water pump leaking, I did take the upper timing cover off and started the car to see if maybe water might spray out from there, but it didn't. Put the radiator cap back on tight, and the leaking pretty much stops. With the car parked and the engine running there seems to be little if any noticeable leaking until the radiator cap is loosened, whereupon heavy leaking immediately occurs from the area I mentioned. Upon inspection from underneath, the coolant seems to leak from above the water pump weep hole from between the lower timing cover and the engine. Not sure whether it's because of a leaking water pump or from a leaking o ring on the water pump end of the water pump inlet pipe which is connected from the thermostat housing to the water pump.
