2.4 200 Water Discharge

[jmadisonbiii]

Just installed a 1988 2.4 200 on a 1983 200 mid. Temp seems really high at idle but goes way down at speed. Pressure is about 2 lb. at idle, up to about 8 or 9 at WOT. Lots of water out the tell tale (when thermostats open), lots of water thru the hub. The previous owner had removed t-stats and poppet valve, I replaced those with new parts. New water pump assembly in March. I'm wondering if I have the water hoses routed properly. Right now the starboard t-stat runs over to the port t-stat, then down to the tell tale. The poppet discharge runs around the rear of the block to a fitting on the port side of the adapter plate. I have been searching here for hours, but still not clear on this. Does the poppet discharge need to tee into the t-stat discharge line? Some people have mentioned running the poppet discharge to the top of the block. Any help would be appreciated. Matt

Any water hose going to the poppet on that engine should be intake, not discharge. You've actually created a "leak" with that routing, and it's bleeding off your pressure.

Just put a pipe plug in the poppet cover for a test, you'll see an instant jump in pressure (I hope):rolleyes:

Then put a tee in the hose coming down from the stat to the telltale, and run that to the fitting in the exhaust plate.

Man, thanks a bunch. Again. I assumed this was a discharge because it shot water out at idle, on the hose. I did see a jump in pressure when I put my thumb over the hole. I will set up as suggested see how it goes. Okay to go ahead and run it hard like that...how much pressure is too much? Thanks again.

These motors are all so different, it can be hard to describe "normal". I would say 15 psi at idle would be cause for concern, and high 20's to low 30's at WOT would be as well.

OK, I will set up as suggested and try it out in the lake. Thanks again.
