Doug, is the 300 TDI radiator big enough to support the 2.8, or did you go with a custom radiator just to optimise plumbing? Trying to get a sense of how big it needs to be. I agree with you about doing it right once, and the best cooling system is my top priority in my next diesel conversion.
From the install manual that I posted the link to:
The maximum engine temperature is 107? C [225? F]. The engine at full power will generate 60 Kw [3400 BTU/min] of heat. The radiator can dissipate the heat generated by the engine via ambient air flowing through the radiator during vehicle motion, or by pulling the air through radiator cooling fans. Electric fans are controlled by signal lines from the engine control module (ECM).
The radiator/fan system must be designed to enable the vehicle to be used at the ambient temperatures desired and not exceed the 107? C [225? F] maximum engine temperature.
Refer to Procedure 387-009 (Air Intake System) in this section for additional information and measurements to
consider for radiator size and configuration.
Looking @ doing a lhd 110 with r380 stumpy next.
