I would like to know what the water temperature is in my PB engine to get better control. Is there a recommended place to fit a sender bearing in mind that the lack of a water pump makes the siting critical, and is there a ready to fit unit available in the UK?

I do have an oil temperature gauge measuring the sump temperature (presumably fitted by a previous owner). I have only ever seen it off the bottom stop once in this cold weather. What is an acceptable range of oil temperature (in degrees pls)?

In the cold weather we are having now (0 - 8 degs C) I think I ought to be blanking off the radiator.

Hello John,

I have PA 1048 (ôMollyö û with a PB engine 533APB) and the water temp gauge sender is fitted in the conventional place in the radiator header tank just to the left of the bonnet hinge. It is an ordinary ether filled system and goes (now) to an original brown faced 2ö Jaeger guage (first I used a black-faced Enfield gauge æcos I couldnÆt afford to buy an original Jaeger, so any gauge will do if it goes up to say 110oC. Since convection governs the effectiveness of this cooling system and therefore I guess the header is as good a place as any other.

Molly runs between 75oC and 95oC but will always boil if stationary for more than about 10 minutes whatever the weather is like (no water pump as you say). I donÆt have an oil temp gauge on Molly, though I do on the NB and, like your P, the sump temp never gets above about 50oC û not hot enough to boil off the condensation. I reckon oil should be at above 80oC and of course on the MGF it gets a good deal hotter than that, as it is designed to do.

Thanks Bob,

The reason why I queried the location of the sender is I did an event on Boxing Day and during it sprung a leak in the top hose. I must have lost all water down to the level of the leak. On a modern pressurised system it would have blown the lot out so there is one more advantage of an ancient!

Anyway all was well as it was so cold that the reduced level was adequate to cool things. However I was thinking that a sender in the expansion tank would probably not have detected this. I spotted a top hose adapter in the Holden catalogue but I suspect that this wouldn't have detected it either!

Its not an original PA radiator but now I look there is a blanking plug in the expansion tank so I will use it.

I havn't experienced a summer's motoring yet so boiling hasn't been an issue. I would expect that boiling when stationary is more to do with the lack of a fan than a water pump.

John
