Check all the hoses for leaks, as well as the water pump and radiator itself. The Thermostat only has to do with the temperature and flow of coolant. Unless there was a leak specifically around the thermostat housing, then that would not be a problem.

Look at where the puddles form underneath the truck and follow the leak up to the problem spot. If you can't pinpoint a faulty hose or water pump, then it is likely that you have a blown head gasket or cracked block.

If you want to get fancy, you can by some UV fluid and a black light that will show you where the leaks are.

For a band aide fix until you can get a new truck (if you don't plan on going through everything to keep this truck) is to use some "stop-leak" "barsol" or other type of thing that can be put into the radiator and ran to clog up holes. This will only work IF there is only a small leak somewhere in the block or radiator. It is often a temporary fix for blown head gaskets, but has the potential of making things worse in some cases, so try not to over use it. If it doesn't work the first time, it probably won't work the next time.

There is a leak somewhere in the cooling system if the radiator is dripping fluid. A new thermosat won't solve this problem, as the system is already leaking.

Replace the radiator if it is leaking.

Look for leaks elsewhere, as well, and replace parts that leak.

Make sure the fan turns on when it gets hot, or when a/c is turned on.

Hope this helps.

Have the water pump checked for operation, also have the radiator checked to see if it may be plugging up. Flushing the radiator may help also.

2002 dodge 1500 Changed radiator, thermostat, and hoses. No heat

Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.

Over heating

Check to see if your water pump is leaking radiator fluid through the weep holes, or maybe a wore out drive belt. good luck.

99 Taurus heater not working.

sounds like you may have an air bubble trapped. Try loosening the radiator cap & running the engine at 1500 rpms till the thermstat opens & see if you can "burp" the air out. You may lose a little coolant this way. shut off car & recheck coolant in radiator and reservoir bottle. Just because reservoir is full, doesn't mean radiator is full.
