A few weeks before the CHCH quake I had a low speed collision in my 96 Camry. Unfortunately I hit a 4WD with a solid bar at the back sporting a tow ball, which pushed the bumper impact beam in just far enough to give the a/c radiator a gentle kiss. The a/c still works.I have not yet checked the sight glass to see if the refrigerant level is down, but I can see that the bottom bracket for the a/c radiator is stuffed so possibly there is a leak somewhere. I have only just this weekend managed to get the bonnet open to see what the damage is. Maybe as a result of the accident, maybe just old age (340,000kms) the engine radiator has now developed a slow leak. Questions: (1) I have heard that radiator stop-leak formulas tend to causeblockages in the radiator water ways. True or false! Is there a reliable product I could use that would do the job, without causing a blockage! (2) Regarding the a/c radiator/condensor, is it worth attempting to source a second-hand item, or am I wasting my time, considering I must pay someoneto discharge and re-charge the refrigerant! If I have to replace the engine radiator, I am not too worried, there are relatively cheap brand-new ones here on TM, but the a/c is a bit more complex as it seems I can't do it myself. The a/c has always worked sweet as and i would like to keep it working if I can, even though it's really an old car now.

Thanks, jjc09, I will try chemweld. ralphdog1, yes, the aircon is still functioning, halfway up the core I can see where the intrusion beam has just lightly crushed a section of cooling fins. I am more worried about the bottom corner where it looks as if the mount is stuffed I can see the plastic is cracked

if the radiator is leaking you replace it you dont add some crap to it i told this my client. he still poured some crap in the radiator and told me it worked . and a few weeks ago the mazda capella was in my shop for a radiator replacment as it cracked the plasric tank propperly now. He was lucky not to have blowen his headgasket also or craked the head on top.He drove about 2 month and what ever crap you add it blocks all the cooling system . chemiweld needs clear water and thermostat out and its used on crap cars to seal craked heads for a while only.

ac dont waste your time with AC if it stoped working then its money down the drain to try and fix it. My old carina had a bend in the ac radiator i pushed it back a bit so it would not rub up against the coolant radiator and it still worked after.servicing a aircon costs loads of money and once there is a big hole moisture will enter the system and thats the end of it or huge bills to extract and purge moisture.

thanks intrade your thoughts on sealant additives like chemiweld are close to my own I will replace the radiator. I can see there is a gentle bend in the a/c radiator caused by the collision, perhaps it has pushed against the engine radiator and caused the leak. When I have the engine radiator out I'll see if I can gently push the a/c radiator out straight again, but I agree that since the a/c is still working no need to spend money on it, the only thing I can see that's actually broken is a crack in the plastic mount on the bottom corner. So: replace the engine radiator but leave the a/c alone for now.

johnf - would you like to see a picture of the cracked bracket! I can't really show you the leak, not sure exactly where it's coming from.

And yes, there are additives that will work, but you are right in the fact that they can or will block up other areas of the cooling system. If I was to recommend one it would be Seal-wel, available from Repco. Or just get a 2nd hand one, get it cleaned and rodded by a specialist and fit it yourself.

I would just replace it with the spare you have. The Radweld would have already caused a fair bit of blockage so you might want to get the system cleaned out properly.

thanks jasongroves and intrade, silverdale is one of the auctions I had on my watchlist, but will check out their website also. I thought their TM auction prices quite reasonable. The trouble with modern cars is the plastic top & bottom tanks they don't last indefinitely, in the old days (my first car was a Morris Minor) the entire radiator was steel and would last almost forever as long as you kept rust inhibitor in the system. Does silverdale supply a/c radiators also!
