RX3 Cooling System

My by-pass is now done

My initial impressions are good but the results are a little limited.

My by-pass internal diameter of 5mm (3/16") is nearly half the size of watt-mans recommended 3/8" and also I'm still using the original stat of 70c.

Out riding - before = 55c - 60c

Out riding - now = 63c - 67c

On the whole the temp remains a lot more stable with less fluctuation settling for the most part at about 65c.

Warm up was perhaps a little slower.

The ability to cool down when the fans kicked in (80c) seemed to be as good as before.

What I think I've gain so far -

No more thermo shock, the engine now warms uniformly

Nearly 10c hotter running temp. This I think is good for the engine in general and good for helping get rid of the contaminants in the oil.

With the by-pass is fitted I'm happy now to fit a higher temp rated thermostat in the future
