"Ballooned" radiator after HGF ??
Hi all,
In a few days, I will take a quick look at a forum member`s ZT-T 1.8 which has suffered HGF. He have had the car at an ex-MGR garage for diagnosis, and they have concluded with HGF. They have also concluded that the radiator, coolant hoses and expansion tank have to be replaced as these has seen to much pressure and have "balooned". The same applies to the AC "radiator". I have never heard of issues like this before and think it sounds strange. Have any of you heard of this happening before? I guess the quick look at that car will give me some more answers to my questions Last edited by Parker; 17th February 2013 at 14:32.. |

I can believe the hoses have split through pressure but surprised the radiator has unless it was so corroded it has sprung a leak. The condenser though?

Hmmm. I think your title may be the wrong way round. It should read HGF after hoses/radiator ballooned. A failure elsewhere in the system had overpressurised (I suspect total radiator blockage) and HGF lets go to relieve pressure.
Not sure about a/c rad though... |

Time will show how things is. I am going to take a look at this one tomorow evening. The guy told me that spark plug no.4 was wet with coolant during dismantling of the cylinder head. He also mentionend something about a broken T-piece or radiator elbow.

It would require considerably more pressure than any cooling system can generate to 'balloon' a radiator. The plastic parts would detach before anything 'ballooned'. In fact the whole thing sounds like flim-flam from a garage on the make. Even the aircon radiator has ballooned'! I ask yer, it's about as convincing as this.
