So I had the car in for some brake system work at the dealer a week or so back. I had them take a look at the cooling system as after a longer drive, I get the distinct smell of coolant. Now the fluid level, when taken to the dealer was on the low side; at the bottom-most acceptable cold level, when warm. They topped it off, but I'm still getting the smell. I've also noticed that the car runs pretty warm, especially in traffic. I have an Ultragauge, and consistently see 220* in traffic, which seems high to me (even though it doesn't register on the dash's idiot gauge.) And it's not like I'm in warm/hot climate, it still Chicago spring, and we're still in the 40's, 50's and 60's.
Dealer did a pressure test, and the system holds pressure. Worthwhile to replace the reservoir cap?
