Angry d24t coolant pressure issue

If those deteriorate and blow, the engine will quickly, catastrophically overheat.

Hard starting sticky.


Possible. Does the radiator hose get hard soon after starting (i.e. before the engine warms up, so before the coolant should logically pressurize from heat?).

Ok I'll start with the fuel lines and replace

What size are the small fuel lines between injectors
Most are leaking so I'll start there
