Car Forum / Dodge / Dodge Cars / March 200595 caravan overheating...but no heat inside
Hey Everyone...my parents caravan is having the issue that it?s overheating, but there is no heat inside the vehicle - just blows cold air. I immediately checked the coolant and it was damn near empty, so I topped that up, but still had the same issues after that. If someone could outline a few things that I can try, with the cheapest fixes first, it?d be greatly appreciated. Thanks a lot. > Hey Everyone...my parents caravan is having the issue that it's > overheating, but there is no heat inside the vehicle - just blows cold > air.

Thanks a lot. It takes coolant to give you heat, if there is no coolant you have no heat..... first thing is to find the leak and fix it. What engine? Glenn Beasley Chrysler Tech what's the temp where you live? if it's below freezing outside and you had a water/glycol mix in there, it's possible that the heater core has frozen up, along with the coolant in the bottom of the rad. not enough in there to crack anything though. warming up the engine won't help, you'll have to move it inside and heat the whole thing over a weekend to see if anything thaws out. of course, this is only the case if it is below freezing where you live. (like it is where i live right now) also, check the thermostat. perhaps the excess heat has damaged the thermostat, (speculation) and that's why, even with lots of coolant, there's still no heat inside. i'm not sure about chryslers, but on the sprint and metro, the coolant from the block through the heater core is directed in a funny way, so with a faulty thermostat, the engine can be overheating with no heat inside at all. > Hey Everyone...my parents caravan is having the issue that it's > overheating, but there is no heat inside the vehicle - just blows cold > air.

To answer both your questions...the engine is a 3.0L V6 and it is well below freezing here where I am (Calgary, AB, Canada)...down to around -15 Celcius the last couple days. There are no leaks from what I can tell...but I?ll check out the thermostat first thing > Thanks for the replies guys.

Is that a definite indicator that the thermostat is screwed? Thanks again, > > Thanks for the replies guys.

(heater core froze), I have not expected that because testing the coolant, which is clean and tests for -45 C. What is the best way to flush the heater core? let me know your opinion. > Hey Everyone...my parents caravan is having the issue that it's > overheating, but there is no heat inside the vehicle - just blows cold > air.

Cost me a a few bucks because they had to pull the tranny out to get at it, but it?s all good now. found the problem, heater core was dirty, flushed it and now I have more heat than I know what to do with.
