Hi all, was at a car show a few weeks back and was chatting to a fellow TVR owner who suggested I changed my coolant to one that keeps the temp down, it cannot for the life of me remember the brand /make.
I know it’s a long shot, but am hoping the forum will give me some hints as to which product would be best for my TVR Griffith 500 (SERP).
Thanks in advance
Carl

Try Evans Waterless, plenty on the subject on here if you search.

Yes lots of opinions and views on this stuff. Certainly controversial!
I stick with ordinary blue antifreeze and change it every 2 years as recommended. Its cheap and available everywhere.

In reality, the cooling system is more than sufficient for the factory cars. Just needs maintaining. When was the last time the system was cleaned through? The coolant changed? Radiator matrix cleaned - both front rad and the cabin one?

'Regular blue' coolant is more than capable and fit for purpose.

I ran mine on Redline water wetter and a lower temp thermostat, had no problems sitting in the traffic at Le Mans for two hours and a trip to Spain in a heatwave biggrin

Indeed Evans Waterless is controversial - you have fully clear the entire system too which isn't plain sailing.

Similarly i think the blue stuff is adequate if well maintained. I've had my Chim for 17 years & origianlly it lived in Hong Kong & had the thermostat removed to control overheating. When repatriated back to UK i fitted lower temp thermostat & Water Wetter while changing coolant every 2-3 years & never had problems despite several foreign queues in heat & humidity.

Doesn't stop me worrying even now but it works & its never let me down even when running at 100 degrees

Do all these people removing thermostats and fitting lower value thermostats understand the function of a thermostat in a cars cooling system confused

I'd love to hear an intelligent explanation from these folks on how removing their thermostat or fitting one of a lower value reduces engine temps and the likelihood of overheating scratchchin

Other than the obvious failed closed thermostat answer, I suspect I'll be waiting a long time for that explanation but I challenge anyone to try hehe

Top tip for the delete/lower value thermostat crowd, first study and fully understand how your cooling system is designed to work and the true role the thermostat plays in that system. The small amount of time invested in your self learning will also save embarrassing yourself trying to convince others why your no thermostat or lower value thermostat idea lowers engine temps and reduces the risk of overheating wink

It will take longer to overheat so a good idea no biggrin

I’m with the water wetter brigade, and standard anti freeze but only to a max of 50% as the greater the proportion of a/f the less cooling capacity.
On lower thermostats - no experience but I would have thought workable. Thermostat removal experience - just leads to a slow temp rise with no end so to be avoided!

I'm fitting a 74-degree thermostat along with a couple of other mods - ultimately an ewp, split fan set up and new ecu.

Reasoning is so that on trackdays I can run a timer circuit when the car is off the coolant system is still running to aid cooling off. Depending on the ecu control the thermostat may not be required.

….Then you're just cooling the water that is static in the radiator.

Ideally, you should have a circulation pump to put the total coolant volume through the rad' with the engine off to reduce the temp of ALL the coolant....or else just leave the engine running at tickover. - All IMHO.

So what does the circulation pump do that the ewp doesn't?

!Aah! Just realised that "ewp" stands for electric water pump (?) My bad - - not good on tla's (three letter acronyms ;-).

Don't worry. I thought it might need a piggy-back system biggrin
