How effective are the leak diagnostics kits

Looking for leaks isn't as black and white as throwing in dye and it will slap you in the face and just show up.

I try to use dye as a last resort. It works, and you don't need to remove it if you don't want. It's messy sometimes and doesn't always make it simple.

I thoughly clean the area in question with brake clean or whatever solvent won't damage anything, then dry it with compressed air. Run the motor and watch. If nothing obvious take it for a quick ride and recheck. If still nothing get it at highways speeds then recheck. If still nothing give it a day or two.

Do you have a physical leak from the coolant or oil, or it just disappearing and don't know where its going.

If there's a physical leak-I would take Mr. Service Writer's advised and go from there.

The new phone book's here! The new phone book's here! This is the kind of spontaneous publicity I need! My name in print! That really makes somebody! Things are going to start happening to me now.

First I get my name in the phone book and now I'm on your ass. You know, I'll bet more people see that than the phone book.

I know we've only known each other 4 weeks and 3 days, but to me it seems like 9 weeks and 5 days.

Sorry, got carried away. Internal leaks are another story. I seen a different post by Abu about a rear main seal, and made the assumption. :Wink:
