Re: Coolant leak

Does it overheat within the first 10 minutes after a cold start?
Has the dash temp gauge read hot at any point?
Maybe the thermostat is fully or partially stuck in closed position.
Have you watched the engine/coolant from cold start to operating remp and loner while engine is idling to find out where coolant is escaping from?

I'm sure it's not coming from the cap. It is fully shut. Brand new cap.

it has never overheated to my knowledge. I've kept a good eye on the gauge. I have watched it from a warm start to operating temp and with a friend revving the engine to 2.5-3k and that's when I noticed the coolant coming out the top. I'll get pictures as soon as I can. No time to do it tonight or the next few days. I'll be out of town with work. Yay...

Re: Coolant leak

Just drove about 25 miles. Radiator is dry, not leaking or messy since earlier. I must have spilled some antifreeze while I was filling the radiator for the first time. I'll keep an eye on it for now...

If you watched the engine (engine bay) from cold to operating temp and saw pressurized coolant spitting out where exactly is it coming from..not sure why it would be hard to find.
Might be a good idea to pressure test the coolant system.

What mileage is it at now and at what mileage did it have the last water-pump replacement? A waterpump can partially/intermmittently fail and push coolant through the system but at a lower rate than normal which causes increased pressure. Coolant should be flowing like shown in video link below and increases with rpms/revving. If you take the radiator cap off when hot open it half way and allow pressure to fully escape before opening. Use a rag on the cap and stand back and don't put face over cap when opening.

Coolant can take a while to burn off..it's fairly viscous. Hopefully you got it sorted. Disregard my post below or use it for a future reference.

Re: Coolant leak

I only bought the car 6 months ago at 197k and it's at 203k now. I purchased it from a tiny dealer so I don't have records. Thanks for your help everyone. I've learned a lot here!
