So I have a coolant leak. It is coming from the area at the bottom of the expansion tank. Hard to tell if it’s the tank or a hose? 100k miles. Are these tanks prone to cracking? Looks like it has been leaking for a while. Radiator light just came on. Replacement tanks seem to range from $25 to $150. How to choose? This thing like a particular kind of coolant?

 

1. Yes, they are prone to cracking.
2. CLICK
3. 50/50 distilled water and Zerex G05 ( flush and refill while you are at it - 3 gallons total )

 

Thanks for the reply! That’s what I figured, got pretty used to replacing these back when I ran VWs.
