Running temps, Australian 409

Thanks for all the help on the cooling matter. In 42C yesterday, with a
brisk drive that included uphill, the gauge just got to under the 100
marker, but no sign or sounds of the of gurgling you can get and at
tickover, no noticable rise over that. Few people were out in modern cars
here yesterday!
I will look at the webosite for the other items.
Has anyone used the new Liquid intelligence coolant? I know it has a boiling
point of 190C and just allowing the engine to get hotter than it's intended
range is not a good thing. No price given on any of their data.
Thanks

Mike,
Despite being in the Monaro region, we do experience temperatures that can challenge the older cars at times (today's temp 41C - tomorrow hotter). I generally find that our 410 temp ranges around 80 - 85. Driving around town sees this go up to 90 but switching on the fans keeps it at around 85-90 in summer.
The radiator and engine block have had extensive flushing and for a while the cooling system had a sock because the car was inactive for so long.
In this weather, I must admit that I retreat to our modern and air conditioning although I am beginning to think about A/C for the Bristol

Thanks John,
I'll get the rad checked and look at higher grade core. I've been looking at
air con too!
I also priced the Liquid Intelligence coolant as a thought - $18 per litre +

When you switched on the heater, you added another radiator! It can be
deducted that you main radiator is not providing enough cooling and I would
have it taken out and checked. Sometimes it is as easy as having the top
unsoldered and mechanically cleaning out the tubes.

Thanks Dorien, Yes I think a simple check first as I've heard of recores
going wrong.
As you say the heater does act as another radiator. When you've got two
Alvis 3 litres, you know of the problems as regards heat. They have a poor
flow through the back of the head and block area.
