m4xwellmurd3r Posted May 23, 2008 Share Posted May 23, 2008 I was reading one of the cooling threads about cylinders' 5 and 6, then saw a post about what happens when you bypass the heater core the improper way. that is, unplugging both hoses and just hooking them together. Doing this causes the hot coolant from the back of the engine, to get recirculated back into the engine, without getting cooled. After pondering on that for a couple seconds, I face palmed myself for not realizing this would cause my engine to overheat like a furnace. Well, looks like I have a little work to do on my Z. and hopefully, I get to save money by doing this! as you can see, my engine has the exact issue stated. instead of the ports being blocked (and allow the engine to internally bypass and properly circulate) mine's only circulating nice hot coolant (note, this picture is wicked old. she looks much cleaner now in there XD) i could also use a handy list of special tools needed to do a rebuild on my engine. I've got a basic metric socket/wrench set up to 21mm, a breaker bar, torque wrench, feeler gauges. I know i'll need a set of dial calipers as well. What type of bolts hold the head on? same with the damper. if someone could PM me a list of required tools needed to tear down and rebuild a Z's engine I'd greatly appreciate it. I've got a 77 FSM but the tools they list are somewhat vauge. they state part numbers and names and a little picture, but nothing solid. (guess i should buy the "How to build your Nissan/Datsun OHC Engine") Quote Link to comment Share on other sites More sharing options...
