Re: leaving the thermostat out

The restrictor went in place of the stat and allowed an improved but regulated flow through the circuit , the small bypass was kept standard.I think one reason it was used was to avoid possible stat failure during an event.

I have heard that the 1800 must not be used without the thermostat as it causes the rear cylider to overheat, as the coooling water takes an easy short cut down the empt thermostat hole. I have seen a baffle plate sold to replace the thermostat on these engines. I have no info on the 1300 engine except to say that the cooling arrangements are very similar.

Don - Ah ... maybe that's the truth behind the theory (see my 30th June posting above) about what happens without a thermostat in place, i.e. it bypasses the rad, not passes through it too quickly. Sounds more sensible, doesn't it?
