Hey everyone, On my 2013 V6 Camaro I got some coolant leaks on a frame and on the passenger and driver side which is going down on transmission. I have already replaced thermostat housing and water pump, didn’t help at all. (Before all of that I did a coolant flush and refill my coolant reservoir it was bone dry) the thing is that if it’s going to the minimum level it’s not leaking at all. And it’s leaking when I start the car only, and than all day and a few days after it won’t leak. Appreciate any help

I went in for an oil change , and my shop pointed out I have a similar issue. When I get it in for a pressure check and diagnoses , I will update on what they found. One thing you can check , is I have heard of the 2 metal coolant lines that run to the thermostat housing , can develop a crack. Possibly check those if you haven't already.
