Too hott my 94 lhs, has been having some heating problems....it goes through antifreeze pretty fast but no leaks as far as i can see..... it keeps blowing the 40 amp fan fuse though..... what could it keep cause this....today a new fuse lasted a few hours?? and i just put in a new fuse and the car was at normal temp but the fans didn't turn on then....so i don't know? any help thanks!!

After engine has cooled, put water in the radiator if you can, not the overflow bottle.
Antifreeze raining down - sounds like a water pump leak, or other SERIOUS leak, in a rubber hose, etc. You can ruin the engine if it overheats! Guage will not work with no water in the engine. Have reliable mechanic check it ASAP

Your problem is in the heater. Maybe just a bad hose. New antifreeze, even the ones that advertise to seal leaks won't always solve the problem.

I have seen the blades on the water pump rot and also seen them loosen on the shaft, either way the water isnt being pumped threw the radiator . This is possible..

If the mechanics are correct in their diagnosis, then that would impact the heating ability of the car to a certain extent. Before I would let someone, especially a mechanic shop, convince me to spend that kind of money, I would get a second opinion. I would recommend that you talk to a Chrysler service technician. No as far as the stop leak goes, there are instances that this would/could work, but it is not a guaranteed fix.You did mention that yu had a couple of issues, and replaced two thermostats. Did you drive, or operate the vehicle while it was hot? In doing so, you may have cracked the head(s) causing this issue.Before you authorize the installation of a new/used motor, there are some tell tale signs that the headgasket is bad, which you can inspect. Is the car using, or leaking antifreeze? Is there water/antifreeze mixed in with the oil? *( This will make the oil appear to be a milky color) Is there smoke (possibly white) that smells sweet coming out of the exhaust pipe? These are all things that you can answer after checking them out. If you are not getting these symptoms, then chances are that you do not have a blown head-gasket.

should be dexcool is it orange? if its not orange then any green will be fine but dont mix the 2 together. The best way to fix an oil leak is to find out where exactly it is coming from

check antifreeze level make sure its full with antifreeze and not just water if full check heater core for leaks see if it is antifreeze on the passenger side floor

check sensor
check actual temp with non-contact thermometer

fix the radiator first.because coolant temperature sensor need to be in antifreeze.when antifreeze get up to 190 degrees. the coolant sensor act as a thermostat.it resistance decrease then the pcm will command cooling fans to run.if antifreeze low the coolant temperature sensor not going to work. engine is going to over heat.

if anyone has the answer to this, i have the exact same problem..
