At idle, the engine gets to about 200-210*. If I put the thing in nuetral and rev it a bit, the temp comes down to about 160*. It does not run above 160* at WOT or any other time. <br /><br />I have installed a new water pump, housing and wear plate. The water comes out of the pee hole at idle, but it's not a very hard stream. <br /><br />Is this normal?

Try replacing the themostats. The reason it cools down when reving is because the poppet value opens at about 2000 rpms and lets the water out of the block.
