Title: Is my thermostat broke????
Post by: Graham.Concept on 16 December 2012, 11:48
my gti was ticking over for a few minutes when thie top radiator hose blew off, emptying the coolant all over the engine. The pipe that came off is the big 1 from centre of the water flange. it has snapped the lip clean off inside the hose so ther no way the hose can go bak on. has this happened because its a really old part or because of a problem with thermostat  ??

I will get a picture up of the flange

its prone to cracking/warping

did your take a long time to get up to temperature?
did your car temperature ever go over 90 just before this happened?

They break, especially cheap ones.
Both plastic flanges are about a tenner a pop, change them both

Wouldn't really start it as all water left in the engine will come splashing out  :whistle:
If it is only 100 yards then first just drain all so it doesn't splash about everywhere.

You will be fine to drive a few miles/mins at low revs.

To check thermostat put it in a kettle/pan and boil to see if it opens.

That driving without water in the engine for any length of time or at any revs can wreck it.
We have all done it and regretted it.
For the sake of a £10 water flange and 10 mins to fit it, its not worth driving it anywhere.
