ROSSCOSM Posted September 1, 2020 Share Posted September 1, 2020 I started out having a heating issue, my car heats up fine and doesnt overheat the heat in the car is fine for the first maybe 30 mins driving then it started blowing cold at 25c. If i turn the heat up towards 30c it gets warm again. I found a small leak on the small hose that connects to the rad fill neck. Ive replace that hose, filled the rad up and left header tank Cap off squeezed the rad hoses til i didnt see any bubbles and waited til the fans came on then went off. The bottom radiator hose still feel Cold however 😩 is it possible ive not waited long enough to get all the air out or am i looking at a thermostat issue? thanks guys Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted September 2, 2020 Share Posted September 2, 2020 The thermostats don't often fail , so its probably a air lock . I'd say its probably worth draining the coolant and refilling but if you do that you might as well chuck a new stat in while its empty . Bear in mind that the rads do tend to crack near that hose that you replaced , so keep a eye in that area , just in case the plastic bits of the rad have a split somewhere 😉 1 Quote Link to comment Share on other sites More sharing options...
ROSSCOSM Posted September 2, 2020 Author Share Posted September 2, 2020 Yeah savage im probably just gonna get new coolant in it its been in nearly 2 years now anyway. I have an alloy rad and it looks fine since replacing hose no leaks been there with the plastic rads before lol Quote Link to comment Share on other sites More sharing options...
ROSSCOSM Posted September 15, 2020 Author Share Posted September 15, 2020 Do you know how much coolant id need for a refill and whats the best to use? I went on Opie Oils to have a look and it says motul stuff but when I looked at the info pretty much every manufacturer except subaru was listed lol Quote Link to comment Share on other sites More sharing options...

savage bulldogs Posted September 17, 2020 Share Posted September 17, 2020 Soz bud , I missed this post . I used motul ingul premixed coolant think it's about 7.5 ltrs in a classic .

ROSSCOSM Posted October 13, 2020 Author Share Posted October 13, 2020 Managed to change thermostat and coolant (when i was supposed to be working 🤫😂) seams to be fine now so it may have just been an air pocket when I removed a coolant hose for access when fitting inlet pipe ( left it off overnight by accident) old themostat looked ok no crud build up or anything just changed it anyway gonna boil the old one in water to see if it is faulty just so i know for reference Quote Link to comment Share on other sites More sharing options...
