Re: 34 heater shut off valve

Hi Dave,
Thanks for the e-mail reply and posting the picture onto the website.
I took the valve off this morning and it is actually in two halves. The top section comprises the heater shut off valve and the bottom the flow from the cylinder head to temperature bulb. The problem was that the hole feeding the bulb was full of crud and therefore was not allowing the bulb to heat up at that point but was getting a supply of water from the heater valve supply.
After a good clean out and re-assmble back on the engine everything was functioning as it should be and totally different readings from the gauge with the heater valve shut off. It now reads much cooler and not so much fluctuation on the gauge.
Once again thanks for the help.
Terry
