When you first plug in the heater have the hood open and in a few seconds you should be able to hear the heater kicking in. It will make a sizzling noise.

If the heater is not putting out heat could it be the thermostat?
If you are not getting heat out of the heater, there are only a few things that could be wrong. The first is low coolant. You can't get heat without coolant running through the heater. If it is low, sometimes it has to be bled of air bubbles. If both heater hose running to the heater are hot, you have circulation. If not the heater could be plugged or not getting the coolant to circulate. There is also a damper in the heater system to stop cold air from bypassing the heater and that needs to be checked.
What is the normal operating temperature for a 1996 cadillac deville with the 32v northstar v8?
depends on where and how you check it. If you are using a laser thermometer on the radiator, it should be about 210 degrees. I assume that you are asking because of poor heat.' if you have poor heating, first with the vehicle warm and heater on high check to see if both hoses going to the heater are hot if they are not, there is a problem with the heater core being plugged or the heater control valve not operating properly. If they are both hot, there is a cabin air filter in your car that is like a furnace filter and must be changed (could be plugged) or there may be a heater control door broken
Why is only warm air blowing when heat is on full after putting in a new thermostat?
The first possibility is the thermostat didn't work. To find this out, after the engine is warmed up u check the hoses going from the engine to the heater, they should be hot. if they are hot then the next reason would be a cable to the temp on the heater needs to be adjusted or the heater core is plugged inside or out.
Why does the heater in your 1994 Chevy Cavalier only blow out cold air?
The heater core is plugged. The thermostat is stuck closed. Antifreeze/coolant level is low. The water pump is not working properly. Check the cheapest things first. Check fluid levels. See if the fluid is circulating well. If okay, replace thermostat. If still cold replace heater core.
2004 Pontiac grand prix heater problems doesn't blow hot air just warm any ideas?
First, check your rad level, possible heater core plugged, vent door problem, feel the hoses at the firewall where the heater core is, if they both feel hot it is not hte heater core, rev up the engine to 3,000 rpm... if it heats up it could be a bad water pump!

Where is engine block heater in fusion?
there isn't one that i know of. usually they are only in trucks to help them start in the winter if you are asking i presume you already have one that is not working.to repair it you must first acquire a new block heater from any reputable car parts vendor . then you must lift the front end of your car,place on jackstands,slide underneath and locate the old block heater. once you have done this ,empty antifreeze,slide underneath the car unscrew the old block heater,this may take a little prying and insert and tighten the new one making sure not to overtighten. now connect the new wire that came with the block heater and route it to the front of the vechicule preferably away from any pulleys belts or moving parts.refill with new antifreeze and check for leaks.if none you have completed the job and give yourself a big pat on the back.
1996 crown vic replaced thermostat but heater appears not to be warm enough where do you start looking?
Most likely there is a air lock in the sysyem. On this model you have to bleed the system right at the heater hose. First, just loosen the hose with the engine cold, so that you will be able to open it slightly. Now, engine running and at operating temp. with the heater on full, open the hose slightly to let out air and some fluid. Do this a few times to make sure all the air is out. Refill the rad. and check it out. If there is still a problem then it is inside at the controls. --------------------------- Low heat can also be caused by a plugged heater core. Touch the heater hoses - ideally they should both be the same temperature. If one is noticeably cooler then the other - then the heater core is partially plugged.
