Hi Im David. thanks for visiting the site. so you have no heat or the blower motor isnt working?

Customer: replied 9 months ago.

The blower is working fine and I did add some coolant in the recovery bottle which was empty or almost empty but it's still blowing cold air. Thermostat inside on the dash was reading right between the H & C. I'm not good with things under the hood so I don't know about the actual thermostat. Should I have added the coolant to the radiator itself? Where is the thermostat and how do you tell if it's working or not? Trying to learn........

Expert:  david craig replied 9 months ago.

ok. to tell if the thermostat is working. once the vehicle warms up to operating temp, both radiator hoses should get hot.

Expert:  david craig replied 9 months ago.

then if they are hot, you need to turn the heater on to high and feel the 2 heater hoses that go into the firewall. both of them should be hot. let me know when you have checked those

Customer: replied 9 months ago.

The two large hoses from the radiator are warm to hot but the small ones going into the fire wall are not.

Expert:  david craig replied 9 months ago.

do you have the heater turned on full blast?

Customer: replied 9 months ago.

Yes

Expert:  david craig replied 9 months ago.

ok, give me a moment.

Expert:  david craig replied 9 months ago.

what does the temp gauge get up to when the engine is running?

Customer: replied 9 months ago.

It just has C & H and it's just passed the middle mark.

Expert:  david craig replied 9 months ago.

does the fan kick on?

Customer: replied 9 months ago.

Yes it does.

Expert:  david craig replied 9 months ago.

ok. good. you definitely have a blockage somewhere in the system. remove the heater hoses form the other end(not the firewall) and drain the coolant, remove the thrmostat and flush out the cooling system.

Expert:  david craig replied 9 months ago.

use a bottle of PEAK radiator flush in the process.

Expert:  david craig replied 9 months ago.

did you have a chance to do the flush?

Expert:  david craig replied 9 months ago.
