While driving back from work this pm accelerated gently from the lights & suddenly temp was heading for the red.
Stopped the car & could see coolant pissing out onto the road. No leaks were visible from above & no water on the engine block,plenty of steam made worse when filling up the rad.
Any ideas where the leak is. It was dripping onto the front roll bar & had been leaking for sometime,(exhaust too hot to crawl under the car) ie gearbox was pretty wet.
The car is running great & checked coolant & oil 1/7 no problems, nice & green.
Also why did the temp gauge only move when nearly all the coolant had gone, the rad was cool.
Had the downpipe changed recently(thanks Danny Fisher)& the rocker cover gasket changed,leaking oil onto exhaust could this be related.
My only hope is that a pipe has been damaged & not the cylinder gasket.
Cheers Mark

 

use the best tool you have, your eyes.

Let it cool then find the leak, it wont be that hard. It's pointless trying to guess wher ethe leak is, could be anything from a hole in a hose to a split radiator.

sometimes water temp gauges only start going balistic when the water has all gone and steam is hitting the sensor.

 

Subaru temp guage stays still between 75 and 98 degrees (ish) so when it moves its almost too late, this is a typical Automotive design fudge (can't have the customers worrying about the temp guage can we). Deliberately designed in, the temp sensor uses a thermistor with a plateau in its curve for just this purpose.

 

yeh, i forgot about that on the scoobs.

Yet more dumbing down of the driver.

Ok so were's the best place to put an after market temp gauge.
After my episode of boiling over I'm keen to have a gauge to give me some warning of melt down by monitoring water & oil temps.
