overheating issues
 

Ok I have another problem again with this blazer and if I can get I running in selling it! I can't take this anymore. I was driving home from work and first I noticed my heat wasn't warm, then I notice my blazer was starting to get hot. So I pull off and I can clearly see antifreeze in the tank. So I was almost home and I shut it off let it cool and got it home. So I did the cheapest thing and replaced thermostat, but still overheated. I check the radiator and there was no coolant at all in there but the tank was full. So filled radiator with antifreeze let it circulate thru and it still overheated. I did notice while it was running and when I was waiting on it to circulate there was bubbling in the tank with the antifreeze that was already in it. I haven't noticed any leaks or spots under it since I filled radiator. What could be the problem, water pump?? I'm so frustrated with this blazer, its been sitting broken down more then I have driven it and its causing me to miss work. I need to get it fixed BC I'm selling it as soon as I can get the temp. Correct to sell it. Please help???

Sounds like a clog. You could try flushing it with water. Also, having the year and some more specifics on the vehicle would be helpful.

Once we have the year/make/model this thread can be moved to the correct section.

where is truck located. Was wondering if you were to sell it. How much? Any details/pics?

Lower intake manifold gasket.
