Engine temp woes
Discussion
LS3 R8 btw.
Driving home, engine temp light comes on, so I nurse the car the 1/2 miles to the next services. Pop the bonnet, sod all water in the reservoir. Top it up with 1.5L, let the car sit, fire it up and it's back to normal again, so off I go. Mile down the road, the light comes back on, 10 secs later, the needle is back down to just below half again, then fluctuates between half and 3/4 for the last mile of my journey.
Had a look under the bonnet again once home, and the reservoir was still full. On the right of the engine bay the coolant pipe coming out the right hand side of the radiator there looks to be a small slit in the pipe. Up until last week it had some crappy aftermarket induction kit on it, I took that off and swapped it for a standard one. My guess is that induction pipe had melted the coolant pipe slightly, but it never actually leaked due to being pressed against it, now it's gone the water is free to escape. However, could this slit be enough to drop the pressure in the system sufficiently to cause the 'engine temp' light to come on, even with plenty of coolant in the system?
Second question, how easy are the coolant pipes to get hold of? Is it something Vauxhall are likely to have in stock? I'm supposed to be driving to the airport early next week.

Just because it's full in the reservoir doesn't mean the system is full - airlocks!Driving home, engine temp light comes on, so I nurse the car the 1/2 miles to the next services.

That's a general comment, not specific to our cars.
Well I went out this morning, checked the fluid levels in the rad, thats fine. Ran the car for 10-15mins up to temp, no leaks I can see, so went out for a drive. Was out 20mins or so, went down the A38 to simulate when the problem hit yesterday, all was fine, some spirited driving on the way home, again all fine, needle remained at just below half all the way around. When I got back though, I noticed this on the undertray beneath the rad:
Could this be a sign that the rad itself is leaking?
