Q: can't locate freon intake valve for 03 jaguar an was wondering were it is located at: There is no Freon intake valve for an 03 Jaguar.

There is a high pressure port and a low pressure port. To answer your question: under the hood. Any other information would likely endanger your life, since this is obviously a DIY question and you lack the knowledge to safely recharge your vehicle's refrigerant system.

Q: Hey YA! I am looking at getting an 01 Honda Prelude this month and valve adjustment keeps coming up when people discuss this car and other cars as well. What is this? Does it cost a lot to do, and is it important? Thank you!: Not at all a big expense most places should do it for $90 -150 including the gasket . Takes me about an hour to do one. If you don't adjust them eventually you could wear the cam possibly although I've never seen any issues from not doing it. If they are too tight then possibly they could've got the engine hot . If they are too loose which is what they should do as they wear they'll just be a little noisy until you get them adjusted if I can help in any other way please let me know hope this helps
