Re: New water pump-no pisser??? WHOA! !!
Try the poppit valve. It gave me alot of trouble when trying to figure out an overheat problem. You can also check for any blockages from that point. I've heard of thermo sensors going bad but that shouldn't change the amount of water coming out of the pisser. Good luck!
Sorry for not getting back sooner. The poppitt valve (Pressure Control Valve, or PCV) for my engine was in the upper casing, above the lower unit. The valve was hidden behind a small plastic piece of trim, I ended up buying an oversized crescent wrench to work on it easier. I'm not sure if the valve will make any difference for you or not, from what I understand they are designed to open, similiar to a thermostat, after the engine has sufficiently warmed up. This is more important for colder climate's but for me in Southwest Florida it's nearly pointless since the water never get's cold enough to make the PCV that important.
I agree with what some other people have said about your thermo's, they can be a pain and can get stuck in nearly any position, including partially opened.
I also ran my air compressor up to a high PSI and blasted the coolant lines, not really recommended but when I was having a problem I couldn't figure out, I went with it. Keep in mind the pisser is only an indicator, if your not overheating, you are getting some sort of flow.
