My 1986 300zx 2+2 N/A started to get warm on me the other day. The temp guage never got to max but it got to the point where I had steaming and hissing going on under the hood. Thought the thermostat was stuck so me and my father bypassed it with a screwdriver to get the car home , on the way we stopped at O'reilly's to get a new one. They had the thermostat in stock but said I'd have to order the gasket if I was to want a new one so I did. Now I've got that ordered but I'm still losing coolant. Fearful of a headgasket I start removing things to see what's going on. I find that the heater hose running off the top of the thermostat housing has a split in it. So i'm trying to get this thing off and it' appears that in order to get to the clamps I'm gonna have to take off my whole upper timing cover, front and back. Which requires me to take the two upper timing gears off? Does this sound right? I'm here to say that the hose is buried behind everything they possibly had available. I guess I was ready to change the CHTS anyway.
