Coolant temperature
I've been doing some work on a Dellow the engine of which has no water pump. I've noticed a 3 or 4 degree rise in running temperature
since filling with an anti-freeze solution compared with just straight water in the radiator.
I just wondered if anyone else has noticed this.

I'm not 100% sure on this, but doesn't anti-freeze boil at a much lower tempreture than water, and therefore diluting pure water with it,
I would expect to see what you have noticed, an increase in temp.
Like I say I'm not 100%, but seem to remember that they only ever use plain water for that reason in race bikes...

Plain water will cool better than an anti-freeze/water soloution.
Anti-freeze is not used in race engines for that reason and also if it gets spilt it is very slippery and the circuits do not like the time it takes
to clear up after an incident.

One of its benefits is it raises the boiling point of your cooling system.

Thanks chaps, I knew I could count on our awesome data base for a definitive answer.
One more question if I may. If the gauge is to be believed (and I hope it is not) it now runs at 95C. Do you think an additive such as water wetter
would work in bring the temperature down to under 90.
Many thanks for you help.

Water wetter dropped the temp of my car <----- by 10 degrees. Worth a try, my guess is it would do something even on a thermo syphon system, maybe
more effective. IMO worth a try fo £14 odd.

to avoid limescal build up, use rain waer of if budget allows, de-inised water from wilkinsons.

Remember some old engines don't like new style anti frezze.

I use water from my dehumidifer (I live in a basement.....).... It's not fit for drinking (fungal spores) but works fine in the radiator....

Reason for the increase in temp is with antifreeze you will get less thermo-syphon effect.
Can't be many Ford 93e engines left surprised nobody stuck a Ford 100e sidevalve engine (which has a water pump) in decades ago.

The great thing about this car is that it is utterly original including its engine. Only 300 Dellows were made and although many still survive, the
majority of those used for Trials are fitted, for reliability and performance, with 105E rear axles and crossflow or pre-crossflow engines. To find
one that has been untouched is quite rare. You are quite right, the 100E engine does have a water pump adjustable tappets and shell bearings so
altogether an improvement all round.

It always amazed me how long the 93e survived in production without all the "stuff" we no take as essentential --- "WOT ! no air
conditioning".
Used to be a PCT man myself with MG TF 1250 and various Imps.
