Help With Coolant overflow

[cbaclawski]

Hello,

I have a 1990 and Something is going on with the coolant overflow. any help is appreciated.

I am far from an expert, and rarely drive the car, so apologies for not using the correct terminology.

Long story short, my car does not seem to "suck" in coolant from the overflow in front of the right front tire. When it heats up, it seems to flow from the main reservoir properly down into the overflow, but it doesn't pull any back in. I get a "low coolant" warning when cold, so I add some to the main reservoir. After running for a while there is a puddle on the ground underneath the overflow tank, the overflow tank is completely full, but the main reservoir is low again...

Could it be something as simple as the cap to the main reservoir not sealing properly?

Any advice welcome?
