It's been raining hard for idk how many days now (hard for a tropical country) and I seem to have some wetness/dampness on the carpet under the driver's (left) floor mat. No obvious leaks or anything. I sealed the fuse box screw holes about a year ago and I don't think it's that. Any ideas?

Now that I (probably) have everything in the coolant system alright I'm getting paranoid about my reservoir cap.

It's a green OE but not Volvo badged cap, and I can hear it hissing after I kill the engine. A bit too soon to say if I'm losing coolant or not.

Another thing is I don't think the ...
