Lots of steam

FLYING BANANA · 15th November 2021, 09:22

Just when you think that my troubles with are Banana are over, then she throws up a new problem.

Back in February I had a new radiator fitted, and I put on a new radiator cap, bought from DMGRS.

Yesterday we had lots of steam coming out of the overflow pipe. When removing the radiator cap there appeared to be no pressure noise. I keep the coolant at the correct level. No oil in the water or water in the oil. Oil cap is clean and the dipstick is showing the correct level.

Started with the onboard diagnostic check and temperature was showing 92 degrees. So we carried on with our trip. The temperature needle stay at the quarter to nine position and I ran with the diagnostic check showing on the dash. On the downhill sections the temperature dropped to 81 and on the uphill bits it went up to 90.

Done a round trip of 80 miles and she pulled like a train. Got home to be greeted by more steam coming out of the overflow pipe.
Been out this morning and no coolant to be seen. I have put about half a pint in.

Could it be the Pressure Relief Thermostat that is playing up? It was last replaced about 8 years ago.
