Besides being a good conductor, why are copper pipes used in underfloor heating?
go to autozone or one of the other major auto parts stores and they can run a quick OBD II diagnostic check and tell you what it is.
told me to check all of the fluids thinking it is probably the oil, he can't check himself as he is working hundreds of miles away. -------------- That would be incorrect. There is an oil pressure gauge and idiot light for that. You can avoid a dealer, but do find a good shop to properly diagnose and repair this issue for you.
The good conduction that you mentioned is a plus. However, a major reason for its use is that copper is much more durable than plastics. This is important during the time that the concrete is placed. You see, the workers get right in there with boots, shovels, rakes and other pointy tools. Any of those can tear or cut right through plastic. The copper is much better at resisting this accidents.
Copper is easy to work and has excellent thermal conductivity corrosion resistance and durability. Mainly corrosion!
You need to go to auto zone they will be able to tell you what the code is. then relay the code to use so that we can help you more.
