AgentZ Posted September 10, 2004 Share Posted September 10, 2004 Hey there guys I really need your help on this one. Seems my moms Z32 seems to like to dump coolant everytime she stops! 90 NA automatic, Seems to have a leak from the pipe running from the front of the intake manifold (from near the throttle butterfly) to what seems to be the cack of the block. I cant tell if it is really this one or not but it seems to be the only likely place for the leak. Is this a common occurence. This is a RHD vehicle and is on the right hand side when facing the engine. Is it an engine out of the car job to fix? Quote Link to comment Share on other sites More sharing options...
technicalninja Posted September 11, 2004 Share Posted September 11, 2004 Multiple heater and intake coolant tubing and rubber hoses exist at rear of engine and below intake. Tube that travels under mainfold to thermostat housing has a flanged gasket that can leak. Will most likely require removal of upper and lower intake. I would suggest replacement of every rubber coolant hose at rear of engine while I had it exposed. Some of the hoses can be replaced with out removing intake (although it requires a contorsionist with small hands). Most important is to get a good diagnosis before ripping it apart. Do you own a coolant system pressure tester? If you don't have it pressure tested by a shop. The tester allows one to pressurize the cooling system to a high level regardless of temp. Top system up, pressurize and look where the coolant will be spraying from. Use real Nissan hoses- they last longer and fit better than any other brand. Some of your hoses will be original, 14 years is a looong time for any hose. Hope this helps Rick Quote Link to comment Share on other sites More sharing options...
