What is the proper procedure for removal of the heater cores on a 308QV? I suspect a tiny leak in one of my cores which is not visible in the box. I'd like to take out each one for a thorough inspection. The passenger side one has an ac component in front of it. Does this need to be removed to get the core out? The reason I suspect a small leak/seepage in this location is because of a very unusal symptom. Specifically, I get a very strong odor of coolant in the cockpit upon making spirited turns--left or right. The smell lasts for a few seconds and then dissipates. It doesn't even happen if the turn is taken slowly and it never happens while cruising straight ahead. The odor is distinct and is definitely inside the cockpit. I suspect it comes through one of the vents, which is , of course connected to the heater boxes. I checked all of the heater hoses ans valves and all look clean and tight. I don't get why this would occur on turns only! Also, I detect no leakage on the ground and the coolant level hasn't gone down. Any thoughts on this matter would be helpful as well as some instruction on the core removal. I'll likely buy a uv light kit soon as well. Thanks in advance.
