The basic configuration of the RV8 (Efi) Cooling System allows the engine to reach normal operating temperature as soon as possible after starting from cold and maintain a stable temperature whilst driving under a wide range of traffic and ambient conditions.
Obviously, It must prevent overheating under any circumstances so the coolants in the closed loop system should readily absorb engine heat and move it efficiently to the radiator where, mostly by convection, heat is lost to the air flow moving over the radiator tubes and fins.
An examination of the Rover SD1 V8 (Efi) Cooling System unearths some routine but often neglected tasks that ought to be at the vanguard of routine preventative maintenance to avoid unexpected and potentially destructive over-heating, yet:
In truth, the Rover SD1 V8 (Efi) Cooling System is often poorly serviced yet is simple to comprehend and the easiest SD1 system to maintain using just basic knowledge and few practical skills.
Paradoxically, diagnosis is not so easy because of overlapping symptoms and causes, so any examination must deal with the logical interpretation of familiar (and some not so familiar) evidence to identify actual fault conditions and determine what and how to fix them.
The underlying mystery is why a simple system is so difficult to get working properly! Could it be that hitherto, diagnostic explanation has completely missed the importance of the underlying fundamental of the whole system, STABILITY? So, prepare to be amazed as all will be revealed.!
Study and learn about the whole cooling process to reveal all its foibles, quirks, fault signs, symptoms and fixes, efc, based upon this simple premise:
The temperature of a fully functional Rover SD1 V8 (Efi) Cooling System will remain stable in all but the most extreme conditions.
