'95 Nissan Maxima, Random Coolant Leak

Q: I have a ‘95 Nissan Maxima. About a month ago I found a puddle of coolant on the garage floor. I took it to the shop and had a pressure test ran. No leaks were apparent except a little from the radiator cap. They replaced the cap and everything was fine until today. Another puddle of coolant was found. The coolant level was fine as of about a week ago. It seems that when it leaks it all comes out at once . Any suggestions as to what this is?..........Amber

A: Random cooling leaks can be troublesome and concerning. Here’s a couple of suggestion in pining down that elusive leak. When you park your vehicle in the garage lay down a sheet of cardboard under the engine. Then you want to reference the cardboard sheet to the vehicle tires. That way when you back your vehicle out you can not only inspect the cardboard for signs of leakage but you will be able to pin point the area in which to look. Because the vehicle has been leak for sometime there should be at least a stain or sign of coolant corrosion. Knowing where to look will really help in sealing that elusive leak.
