SilverMachine Posted November 17, 2021 Share Posted November 17, 2021 I recently bought a replacement rad after turning up for work like a steam train the other morning. Once fitted and filled, I ran the car up to temp and took it around the block to release any trapped air in the system. Within a minute I had steam gushing out of the top of the rad. After several hours, I went back to the car, took the cap off the rad and turned the key. The water gushed up and out of the rad like a 6ft fountain. Not sure why this happens now. I hope I haven't blown the head. No water in the oil. I have changed the thermostat thinking it was cooked. Any help would be grateful. Thanks, Gaz Quote Link to comment Share on other sites More sharing options...
evinX Posted November 17, 2021 Share Posted November 17, 2021 (edited) Take the thermostat out and see if its stuck using 1 boiling cup of water and 1 cup of cold water. I THINK tbe hot water will open it and the cold will close it. Edit, seen you did the thermostat. Did you fit it the right way around?

Thanks evinX, I removed the brand new thermostat from the housing and 'doctored' the old one (took the guts out of it, just leaving the seal) and put this in. Still did the same thing. When I turned the key before, it would idle normally with bubbles and whisps of steam from the top of the rad. Now it's a torrent of water straight up!

Top bloke. Already spoken to him earlier. He says just keep flushing the system 3-4 times to see if this sorts it. Thought I'd see if anyone else on here had a similar issue. 1 Quote Link to comment Share on other sites More sharing options...
