Coolant Leak - Running Out of Ideas

[Tranlm]

Since the pressure is decreasing slowly, my guess would be one of the gaskets.

Good luck though and please keep us updated! Thinking about it, it might be easier if you were to take off the bumper to expose the radiator, open the engine compartment, jack the car up, and wait til night time before running the car and UV light. Should make things easier and quicker for you.

That's odd, I had a bad leak and had to replace the water pump, I also replaced the cap and belt. After I did this there was no leak but I noticed a smell. The coolant did not drop so I did not pursue it.

Please let us know what you find out, Thank You.
