Small Antifreeze Leak - need advice

[PaganEgyptian]

Dont use any of it.... Napa has rental pressure check pumps that attatch like a radiator cap. Put the system under pressure and look for a leak. It could be minor like a hose or something. To pressure test the coolant system should be inexpensive at a shop. Fittings to the radiator are often the culprit, check those too.

I've insisted for years that my '00 Toyota Sienna minivan w/ 86k miles has had an antifreeze leak ever since I got it. Several Toyota dealers pressure tested, drove, kept overnight, etc. and could find no evidence...same with independents. Sometimes I will notice a small puddle (couple tbl. spoons worth) under the engine.

I have learned how to add antifreeze myself and we always bring some on trips b/c it seems it needs to be filled often.

Sometimes the water pump will leak a bit. They usually go out not long after they start leaking but sometimes they drip and drip but last. I personally would change the water pump if thats where the leak turns out to be. EW
