Y’all These seep spots don’t really justify how much coolant I am losing 🤔

For example, I filled it up this morning to the full one cold line, took a drive to the gas station and back, which is about 4 miles there and back and it dropped like a inch and stayed there even after cooling down. No pressure in hose either.

I’m really trying to decide if I should pull the trigger on the radiator or something else is wrong here. Obviously the radiator is seeping, but like I said, it doesn’t really justify how much coolant I lose.





Here you can see some coolant seeping on the driver side side tank.

This photo was taken on a cold engine, after going for a drive to the shop and back which is 4 miles in total. And I topped it off before leaving.

 

Welcome from Florida. Don't start replacing parts before you are sure you have the right one. That could get expensive. It could be a hose, radiator, freeze plug, water pump, etc. The spots could be on the opposite side of the motor from where the leak is.

 

If your system is down alot on coolent, it can pull alot from the reservoir replenishing with each heat/cool cycle. Maybe your small leak has gradually drained alot of coolent, so now it's catching up as you replenish the reservoir. Keep refilling with each drive, see iof it slows down. And +1 for don't use the parts cannon. Figure out the problem and correct as needed.

 

it does seem like it’s getting better. Gonna check it at home again after work. Not driving it currently.

 

Florida? Im
in South Dakota man. Wish I was in Florida. Wouldn’t be dealing with cold snaps and brittle plastic
