Driving back form Milton Keynes to Shropshire on Sunday came to the usual M5-M6 Jam and.....HOLY MOTHER of GOD
, The temp is at 115...great piles of brown shhhhhhugar. No red light - just a rising guage!
put heater on, the traffic moved and it came down slowly from ther to about 70, when crusing!
Still have to diagnose the issue as the fans did not come on. I am not losing coolant so hopefully have not sprung pressure leak in the water system. Probaly fans failed due to the usual connectors/fuses/relay/otter.
It is a Chim 450 '97.
Question is...will there have been any long lasting damage?

I had 120 indicated during the 37 degree heat wave after caning it down the motorway and hitting a wall of very slow moving traffic (N plate 500). Went on like this for around 30 mins with heater on.
Had to get someone to an urgent hospital appointment so gambled on carrying on.
4000 miles later the car still goes (and after a subsequent overheat due to blown fuse! - was hungover and was not paying the usual attention to the temp guage).
Its in for a service today, so I am waiting by my mobile half expecting to get a 'sorry its terminal call'.
We shall see.........................

On the bright side, temp gauges are known to be vague at best. 115 might only have been just over 100.
Mine regularly (4.0 98) runs at 80 cruising then straight to 90 in traffic. At 92 you hear the familiar whirr of fans cutting in, and they just about manage to hold things under 100.
Have a look at the temp on your eurobox (if you have one) - normal running temp for my 156 is 90, red zone is 125 never been above 110. Rover V8's are not that fragile - susceptible, but not that fragile.

Rover V8's are not that fragile - susceptible, but not that fragile.On the bad side, my griff reached 105 degrees (not normal) and on stopping I found a head gasket problem with water in the oil. If I had pressed on with the "they all do that, sir" attitude, the end result would have been two new heads as the next stage is for them to warp and become U/S. If the car is hitting that sort of temperature, there is something wrong and yes it could damage your engine and give you a big big bill. Yes it might be the guage but do you feel lucky?

Well hopefully I have been (lucky).
Car came back from service with no reported faults, Mark Adams chip and ACT Trumpet base. Lovely!!!
I'm touching wood, but the car seems to be fine, I would have expected any faults to have made themselves known in the 4000 miles since the 120 incident. I am going to get the temp gauge checked before next summer though!!!

Fans not always kicking in may also be down to a faulty otter switch (i.e. the switch that turns the fans on and off). Think that these are quite cheap to replace.
Yes, this hapened to me a couple of years ago in Newcastle. Was busy chatting to my mate who I was visiting to help him check out an Elise, so wasn't watching dials, but then I noticed steam coming through the bonnet vents
The fans weren't working and after letting it cool and getting a clear run to Hexham, HHC took pity on me and there and then changed the otter switch. It took a couple of hours [mainly time to let the engine cool to a safe working temp] and cost about 35quid. Superb service since I wasn't their regular customer [Harrogate HC is my dealer].

mine has been hot a few times. enough to discolour the coolant on one occasion.
touch wood though i have done 7-8k since then and it's fine.
got the oil changed and the cooling system flushed soon after though!
this was down to the fuse fault. have wired a supply from the starter now, and can replace my 40A much more easily ( any auto factor job, rather than tvr dealer slow blow ).
have fused the other fan seperately ( only one fan supply re-wired and used the original supply to switch the auxilary relay ).
the re-wired fan goes like the clappers. if i was going to hang onto the car i would do the other as well.
i daresay the otter over-ride is worthwhile, and a lower switching otter can be fitted as well, which makes the temp in trafic climb much more slowly.
