Can a faulty radiator cap can cause air in my heating cold. We had below 0 degrees temperature in my home state I went outside to start my truck make sure battery was good. It made a noise coming from the pulleys and after that I can hear water gurgling from my dash board. It’s not overheating or oil in my coolant.
My car only has a cap on the overflow tank, not on the radiator. 2002 chrysler 300m but I'm having problems with my cars heat. The heat works for a little bit then blows cold. I just noticed that the seal on the cap is brittle and falling apart. Can this cap be the problem?
Any idea why my overflow tank is always empty? I have filled it, and then when I check it a few days later it’s empty. It’s always empty but the radiator has coolant in it. I don’t see a leak anywhere. 🤷🏾♂️
After driving, turn off the car pop your hood, and look and listen for hissing or bubbling. After it cools down, take the radiator cap off. See if it's broke. My 97 accords cap was broken and I had to retrieve the spring from the radiator. Also check your oil cap, and dip stick. If the oil looks milky, then you have a head gasket leak.
You can have a pressure test done as well to your coolant system. Just be careful going to shops. Something they don't diagnose correctly and assume that it's 1 thing or the other. It literally can just be the radiator cap or the thermostat gunked up or malfunction Or your fan relay not functioning. It can be so many simple fixes
Just seen your video. Can the bad radiator cap ruined the radiator? Going to the 3rd radiator. Checked for leak on head gasket checked out good. And when I installed new radiator I did not replace the cap.
1. Make sure it's the correct cap 2. You have to push down (kinda like a child safety thing on medicine) and turn. 3. If it's still not working check the radiator, the neck, where the cap goes. It could be broken.
Did you find the problem? I do have the same problem after I use the car for few kilometres I do run out of coolant but I did find even the cap damaged.
