Reply With QuoteIt was a rather hot day, perhaps the outside temps pushed the radiator fluid a bit and it bubbled... I've had it happen several times now. No overheating, but close enough to cause a slight concern.
Boiling Coolant?
Can someone tell me why my rad fluid was bubbling (boiling?) today after driving it spiritedly in the middle of the day?
- Coolant level looks good.
- Is about a year old and a 60 H2O / 40 AF mix.
- Temp gauge stayed in the middle the entire time.
- It started bubbling after I pulled into the garage and turned the car off.
- Guess it could have been doing it as I drove?
- No leaks or overflow loss.
- I turned a fan on to run air throught the radiator and left it to sit and cool down.
- Drove it tonight and no problems or bubbling.

When was the last time you replaced the radiator cap? It was the cure for my car.
YMMV.
A new radiator cap and t-stat should help.
Still, don't forget that after a "spirited drive", if you shit the car down and park it, the coolant stops circulating. It's not uncommon for the coolant in contact with the block to boil under those kind of circumstances, when the engine is really hot.

You do what?Originally Posted by altiain
Mine boiled/gurgled one day last week after a 'spirited' drive home from work. Coolant, T-Stat and radiator cap are all less than 1 year old.
Same here... although I think if I replace my underbelly tray it won't happen as often.
I don't think pooping on your car is going to help!You do what?
I'd try the Radiator Cap first!
You can switch to a rx-7 cap. That will bring you up to a 16lb system instead of a 13lb pressure

Dammit! I need to detail the car now thanks to Iain!I don't think pooping on your car is going to help!

After I hose off all fecal matter I will buy a new radiator cap.
Any idea on what year RX-7?
I know it's only a 3 psi increase but can the OEM plastic radiator handle the task?
I thought consensus was that it couldn't deal with it... that Miata OEM was best.I know it's only a 3 psi increase but can the OEM plastic radiator handle the task?
Sorry, I've got an aluminum. I keep forgetting about the stock limitations.
