Engine temp normal?

[WhyTwo]

I've had 2 instances of coolant problems recently - 1 led to the car overheating in traffic, the RAC being called and me being stood by the side of the road for 3 hours. The fans hadn't kicked in and both temperature sensors were subsequently replaced. Next time the car dumped coolant on my drive and needed a hose replacing, no big deal.

Anyway I now find myself constantly looking at the temperature gauge hoping I don't come across any traffic jams and worrying everytime the temp gets to the mid 90's hoping the fans will cut in - not great if you have a long drive planned ala Le Mans in June!

So my question is this - is the fact that my car's temperature easily gets into the 90's when sat in traffic for a few minutes normal? (when not sat still it's usually around 80 degrees) Should I be worried? Has anyone on here fitted a manual override and is it straightforward?

On my car both the fans have cut in by 94 degrees. Mine are noisy and I can usually hear them in traffic if I listen out for them.

But I know what you mean, I am always a bit nervous as the temperature rises!

I've looked on the TVRCC forum and there's a post saying the fans should come on at 91 - 92 for the first one and then 94 degrees forthe 2nd. My first fan doesn't come on til 94 degrees. I guess the temp reading might not be 100% accurate?

I think I'll do a test next time I take the Tuscan out. When I get home I'll leave it running on the drive to see when fan 2 kicks in.

The temperature on mine normally runs at about 75 but will increase rapidly to 96 in traffic. Never goes above 96 though. As per previous post you can hear the fans kicking in and if you miss that you can "see" the hot air being blown from the fans when sitting in traffic.

I just hope you have understanding neighbours

Hi guys my fan's kick in at 96 is that ok??

Fans kick in 90 ish.
There's going to be a bit of variation due to sensor part-part variations.
All posters temps sounds normal to me.

Been using mine as daily driver the last couple of weeks, Genrally it runs around 88-92, in traffic it sits around 94-96. Left work bout hour and half ago and thought I'd go for a quick blast long way home seeing its nice and sunny (back window out)> outside temp here is 14 degrees and in traffic as i got close to home the temp is as above 94 degrees after a good blast!!!

Thanks for your replies. Seems mine's within expected levels so I guess I'm just paranoid! Suffice to say I'll be keeping a close eye on it nonetheless!

BTW I was reading on TVRCC and a manual override switch is not recommended as it can confuse the engine apparantly??

you can lower the temperature the fans turn on by modding the ECU. Joolz offered this service and is a popular mod on the Cerbs as well. Anyone who can mod the ECU will be able to do it. Joolz set it to around the mid 80's I think.

TVR power do a 'cooling chip', I think that brings both fans on at about 88 Deg.C.

I have found on both my Tuscans the display sender reads 4 to 5 Deg.C higher than the ECU sender.
