helping a friend out.. 99 supra. indmar 350. have replaced thermostat, but on a fake a lake wont draw water up past the first water pump.(impellar looks to be in good shape as well) seems that the engine is back preasuring and not allowing water into the motor? pretty much checked all hoses and passage ways and none are blocked.
drove to the lake... make sure had enough water and the engine temp just rose up more and more.
is it possible bad head gasket or cracked block is causing this? he just tried to take it out 2 days ago for the first time since last winter... was stored in a storage shed but not heated.
