Had a nightmare of a day changing the thermostat on the signum cdti 120
I was shocked just how much work and effort is involved in changing this piece
After 2 hours i had to have a lay down because of the cronic back ache that had set in,it took me 5 hours in total
When refitting i cut the lug off the heat exchanger that bolts to engine just to save more time with an air saw
The car now sits at 85 degrees and its great to have hot air in the car but where the metal pipe that goes into the heat exchanger is leaking(cant have mated them up properly) so now it has caused unbelievable turbo lag
Will try to mate pipes up better tomorrow as i feel and look like steven hawkins at the moment
