Sprung a coolant leak

The plastic radiator inlet/outlet contracts in the cold and can cause a leak. I have had them leak and it usually appears in the late fall early winter. When the plastic warms up, sometimes the leak will temporarily stop. (for a while) It's an early warning sign. The hoses themselves also age and get less-flexible and hard over time. The quick field-fix is to snug up the clamp a little. (if it's a screw clamp like yours is: just don't over do it.) If it was an OEM clamp, the s-o-p is to replace the hose and the OEM clamp. Be gentle removing the old hose from the plastic radiator connection: They get more fragile as the plastic ages and may break off if you twist and muscle it trying to pull off the hose. I cut them off with a razor cutter near the end of the connector and then remove the piece left on the connector with a single straight cut and gently peel it off.

 

I already ordered new hoses anyway, I’ll get new OEM clamps to go with em. The other hose still has the oem clamps

 

Get an Aisin rad cap or OEM. I don't trust Stant on any of my Toyotas.

 

Found the actual source of the leak. The battery wire harness anchor bracket rubbed a good chunk out of the drivers side hose and made a puncture. Replaced with HPS silicone reinforced hoses just because. Used OEM spring clamps.
