Coolant smell in expansion tank area

Coolant smell in expansion tank area
Ive had most of my coolant system replaced but there is a major smell of hot coolant around the expansion tank area. I've looked everywhere and finally found the faintest leak around the main host under the tank. I can't believe this small drop can cause such a smell.
I've ordered a new tank but my gut says its more than that. It's the original tank so I know they're prone to failing.
This is the last issue I have at this point and it's driving me insane!!!! Should I be looking at any other hoses or clamps in that area that I may not be ale to see easily!!
HELP!!!!

On my car, one of the short pieces of rubber hoses connecting to the tank, had developed a small leak. It was a very slow leak, occasionally dripping coolant onto the hot exhaust. It made a terrible stink, for such a small leak. The repair was easily and cheaply done with a 2" piece of hose and 2 aftermarket worm clamps. I think it cost $1.50 and 10 minutes of my time to fix. Oh, and I topped off the tank with coolant. The coolant level sensor works well and is pretty sensitive to being even an inch or so low. If this is your problem, be safe and attempt the repair on a cool engine, so there is no chance of being scalded.

Something to look at is the plastic three-way connector that one end of the bottom hose from the expansion tank goes to down where the large hose comes out from under the intake below the throttle body. I just replaced it in my '01 XKR as it was cracked and leaking. The part number is JA NNE3944BA. That might be the problem.

I got the same smell and learned mine just went south after replacing some coolant lines. I think when the lines are removed from the tank, this may stress the plastic, possibly leading to a leak when the car is driven and pressure builds. Considering the age of these cars and the weakened plastic it might be a good idea to replace the tank at the same time the heater hoses connected to it are removed.

Hey Phil, I had the same symptom. Take a good look at the plastic fitting that connects the octopus hose to the engine coolant hose... its on the l/h side of the engine., toward the rear of the engine and above the l/h cat. These plastic fittings rot away and begin to leak. I made a replacement out of brass, let me know if this is your problem... I can walk you through making one.
