on my way to santa pod today my car overheated down to a failed fan switch how likely is it that the headgasket would have gone? i didnt take it up the strip to be safe. there is no somke or nothing at the moment. is there away of checking i heared you could get something to put in the water and if its gone between the water jackets the water will turn a different colour if true where can i get it from advice welcome thanks.

its a group a one if that makes any differance.

 

Did it overheat or just get hotter than normal, ie was it pushing water out the expansion tank ?
You can get a test kit, but a cheaper way is to gas sniff it at MOT place, as the air in the tank will have CO in it if gone.

it would take a Very bad overheat to do the head gasket would it not?

 

yes did over heat quite bad didnt spot it till my missis pointed out it was in the red. i pulled over an it had empted the water tank all over the floor.


just cheacked the water and its a bit oily gonna flush it all out put some fresh water in and see if that goes oily.

 

or i might of checked it lol

 

i popped a core plug once and didnt realise,the journey was 10 mins, i looked down and the needle was off the red, dont know how long it had been there neither, head gasket was ok so hopefully you should be ok mate

 

I'd be surprised if it had gone from what you are describing mate. I assume it held water once it was topped up? Gauge senders often pack up after a boil so watch out for that.

 

Here hoping all is ok for you, fingers crossed!!

In a similar situation with mine mate, although I dropped coolant on a top speed run at brunters!! Its booked into Reyland saturday for diagnosis - not looking good as its missfiring and steaming out the exhaust badly!!

Hope all is ok for you.
