03 May Servicing Tudor Rose – Step 10
One of the important components of a cooling system is to ensure that the radiator water is treated to give the best performance. For the o2o OZ I am using Penrite products entirely. In particular I am using Penrite 10 Tenths RACE COOLANT. This is a coolant that lasts 3-5 years and reduces ‘hot spots’ especially in older cast iron engine blocks and heads and helps reduce small steam pockets that are sometimes caused by water having a high capillary attraction to odd spots in the engine. My experience is that Penrite 10 TENTHS RACE COOLANT prevents this from occurring resulting in more efficient cooling.
