hey guys,

i put a new rad, thermostat and coolant pipes on the other day, put plenty of coolant in and bled it,
never lost any coolant before,

yesturday i did about 50 miles, when i got in my car at 3am as soon as i started it up the coolant light came on, stopeed straight away and realised there was barely any coolant in there! any way topped it up and it doesnt seem to have gone down ,

could it have just been an air block? im hoping so but if the system is under pressure as i didnt have the cap off at all how would the air come to the surface? theres no coolant in the oil and cant find any leaks.

please help me asap as i am supposed to be driving to the trafford centre in about an hour lol.

Not sure dude, sounds like you've left a pipe disconnected potentially?? When the car's sat still, is there a visible leak underneath? Perhaps stick a hosepipe in there and keep it running gently to identify the leak from underneath?

ok guys u wont believe waht happened today, toped up the coolant up and put a rag around the cap.

checked it when i got the the trafford centre only about 15 miles away and realised it had dropped a bit but not too much, no wter on the rag.

then on the way home stuck in a traffic jam i noticed a bit of steam around my bonnet. then some more and the temp was at 3/4 (100c) then a sec later the coolant light came on . i rolled on to the hard shoulder lifted the bonnet up and steam poured out every where and there was coolant all over the rhs of the engine bay!

one of the blooody pipes had burst on me. luckily i pulled over straight awya so didnt over heat at all....

as u lot know ive just changed the 2 big coolant pipes as they were old and kept expanding and i didnt change the others even tho they did expand a bit. obviously should have done now. the leak must have been a very slight and then the pressure build up must have blown the pipe....

but why would this happen? just an old pipe? or excess pressure? no bubbles come out of the header tank etc and no steam out of exhaust etc so i doubt its teh HG . plus HG was done 27k ago.

thanks, any suggestions other than changeing the pipe?

Yep, all Calibra's go through this. Thankfully you won't be getting any burst that have already been replaced. So once it's done... it's done!

I would seriously look for underlying problems. Why are they popping off? Compression in the coolant system is one strong possibility (which means leaking headgasket)

I had something similiar to this with my old 16v Calibra ... I'd replace 1 water hose and then before I knew it the next on the circuit would go , so I'd replace that and then shortly after the next one went. After all of them had been changed I had no further problems. I put it down to all the pipes being old, worn and weak, when the engine was cold the water level would be the same as any other calibra but when the system was under pressure the hoses would expand until 1 finally went, when this was replaced it was stronger so the the water had less room to expand in and therefore the pressure went up blowing the next pipe and so on and so on.

thanks for the replies...

i think it is just a matter of the pipes being old, as i said if it was the HG there would be bubles coming up through the header tank and even when i floor it nothing comes up.. (with the cap off obviously)

any way i had a look this morning and the pipe had ripped right next to the jubilee clip...

it is the pipe on the RHS of the block, not that big about 1 and a half inch big. so i just chopped the ripped end off and then connected it back up, should hold until i get a new one...

any one know how to chagne this pipe???

i cant find where it goes as i think it goest to the heater matrix ? as it dissappears through the bulkhead!
