Mulley's New 19TXD

[MULLEY]

I think he said that it would pay for their lunchtime sarnies

Slightly more worrying is that since the last meet, the amber temp light has been on twice now. I've checked the fan to ensure it does actually rotate, but thats about as fars its gone due to weather. I'll probably give Shaune a buzz to see if he's got any ideas, i'm hoping its just a dicky sensor, car drives fine though.

unusual! the orange lamp of impending death usually does nothing, just sits there smug whilst the red lamp of death comes on, just after the pistons have picked up..
It's pretty common for the sensors to go nuts as they age, so hopefully you'll just need a new one!
When I fitted the temp guage in mine I bought a new sensor for the lower setting (the one for the orange light of death) and use that for the red light of death, that having been replaced with the sensor for the guage...

Exactly what I did.

When the light came on, were you stationary? If not then it's unlikely to be anything to do with the fan since when you're moving you'll have a good airflow anyway. Was the engine working hard at the time?

We had both lamps of doom on on the CCC. I stopped straight away and let the engine cool with no problems, may be worth getting an override switch fitted as Mat/Phil B did.

The 1st time i had the car running when parked up whilst chatting, & spotted it when i was a few miles down the road, it went out after about a minute of driving. The 2nd time i was going up a steep hill with the engine working reasonably hard, again it wasn't on for long as i could speed up at the top of the hill & then it went out.

Assuming there's enough coolant in the system, it may need flushing through

[MULLEY]

Plenty of coolant in the rad, i also had it tested & it was good to minus 25. A flush is probably a good idea anyway, which i'll get done when i change the coolant.

[mat_fenwick]

Given that both situations were when there was either little or no airflow through the radiator, I'd first check the fan is cutting in. You've at least checked that it's not seized but not the electrical side.

[MULLEY]

Not that good with electrics, is there something that i need to test with a multimeter?

[docchevron]

get yourself a short bit of wire, pull the rad fam switch plug off, it'll have 3 pins, one on the top, one either side. stick one end of wire in the top pin, and the other end in either side pin in turn, the fan should run half speed and full speed, depending on which side you connect the wire to. if it does, you know the fan itself and the wiring to it is ok which then points to the rad switch itself being duff, cheap and easy to replace.

[mat_fenwick]

/\ Yeah, that. But I'd add that you don't need to do that if then fan cuts in OK when sitting stationary with the heater off)
If the fan doesn't work then you need to go down the electrical side and find out why; if the fan does work then it's either the sensor for the yellow light being over eager, or the cooling system not being effective enough. So several possibilities at this stage but if you work through it logically you'll get there.

Cheers guy's, it briefly came on again today whilst i was moving, probably only on for 30 seconds. Everytime it comes on i get a bleedin panic incase the RED one comes on

[docchevron]

you'll know it's bad before the red light comes on, that usually reserves itself to inform you the engine has already seized...

[Wooscary]

My orange one appears to be on all the time, but in actual fact it's due to a bit of the instrument panel having moved slightly at a join, exposing some of the back lights.

I know this because when it did come on it was a lot brighter, and a lot more scary!

[MULLEY]

Exhaust has decided to snap off again due to rusting bodywork, managed to zip tie it all back up & it manged to last today driving over sheffields finest (cough, i mean shitest roads evah) without falling off. It's got to last a week before Shaune & his welder are available, i'll have to drive slowly
