I'd try a new shop. I've replaced dozens of these suckers over the years and never had a problem with leaking at different pressure levels. Sounds like voodoo science... BTW: When you replace the core, you should also replace the valve & o-ring. Cheers, Jeff www.vanagonparts.com

I have a rear underseat heater on an 85 Westfalia that has made a complete fool of me. I have a small leak that arises somewhere in the core or at the valve and each time I think I have it fixed it comes back to haunt me. Finally took it to a radiator shop and they recounted their own problems with them. It seems that each piece of tubing is embedded discontinuously so that leaks can arise at either lower or higher pressures where the pipes enter the end manifold and there is nothing that can be done about it. I have had that heater in and out 6 times. This guy said that he has watched cores that are perfectly sealed at 30 PSI and leak like sieves at 15 PSI. It will never do that to me again----I beat it to death with a sledge hammer. Please don't let it make the same fool of you. It used to be that as a young man I had endless patience for such nonsense, but no more. I find that the sledge comes out more and more frequently now, may eventually take it to the whole vehicle. I am not proud of that kind of behavior, but not too ashamed of it either. |
