    The dial is normally at about 25 when the car gets warm but i put it on about 30 to warm it up. I did wonder if it was the thermostat, are they easy to fix and were are they located in the car.

    Oh right, sorry. It is a manual, the temp gauage is always in the middle, hope that helps.

Where is the temp gauge reading? If it is below half-way up, your thermostat is sticking open, and the coolant going to the heater is not at the proper temperature (192 degrees F) to make good heat. Replace the thermostat, and this will solve your situation.
Hope this helps, and thank you for choosing FixYa!

    I was inquiring about the Engine Temperature Gauge", no the heater temp 25/30.

    Please advise of the Engine Temp reading. Also, please advise if auto or manual transmission. Thanks.

    Is the temp gauge ALWAYS in the middle, whilst you are driving?

    If so, replacing the thermostat is going to be a waste of money, because that is NOT your problem. As long at the temp gauge is in the middle, the car is at the right temp of coolant.

    Now, since I am now armed with the additional information that you have provided, I must change my solution from thermostat replacement to:

    "I suggest that you get your cooling system power-flushed"; by a professional service.

    There is no doubt in my mind that your heater core is partially plugged or blocked, and you are not getting sufficient hot coolant flow thru the heater core. Flushing out the cooling system will dislodge the blockage in your heater core, and restore your heating efficiency. This will cure your issue. The graciousness of a "FixYa" would be greatly appreciated, as this helps us experts on the "free" portion of FixYa.

Replace the thermostat! its right under the wire pack the spark plug wires go to on the right side of the engine. be sure to get some RVT silicone or you'll be cursing up a storm.

I put a new thermostat in my 1994 ford escort,and still dont have warm heat while my heater is on. How do I test to see if I have a bad waterpump?

If it where your water pump isthe vehicle would overheat. After you replaced the thermostat do you run the engine at idle with the radiator cap removed until the radiator fan came one? This will help push the air out of the system. There are two other possibilities. 1. The heater core is plugged. Back flushing the heater core may help remove the built up debris and get you heat again. 2. The blend door may not be fully transitioning from cold to hot. You should be ale to hear a district change in how the air sounds when switching from full hot to full cold. Let me know if you have any questions and I'll do my best to answer them. Thank you for using!

I just bought a 1994 Subaru Loyale, the heat is not very hot. The fan blows but the air is warm not hot. The previous owner told me when he replaced the water pump he also put a new 195 degree...

very important to have proper coolant solution.50/50..too much antifreeze will make heater act up.antifreeze tester will eliminate that.warm engine and check both heater hose if they are the same tempature.if not remove both hoses and garden hose through the
heater core to flush both ways.try not to disturb the heat core and remove hoses where they connect to the engine.let me know if that helps

1990 Toyota celica 1.6 overheating when it runs for about 6 miles I changed water pump and thermostat it's not blowing any water out of tail pipe and no water in oil what's should I do

Start vechile, let it warm up, turn on heater, is there heat from the heater?
No? You need to bleed the system better. Jack the front of the car up, remove radiator cap, while throttle is increased add more coolant, then with throttle still increased put radiator cap back on and release throttle. Is there now heat?

Heater not working on 1994 528i bmw but ac blower works

Hi it sounds like either the thermostat or the heater matrix, although if there is air in the system then this would also cause this fault. get the thermostat checked first as this could cause more damage if not fixed quickly.

The heater matrix or heater core may be blocked or not circulating the warm air, This is a more expensive job if it will not unblock.

Hope this helps

My 2004 toyata celica takes forever to heat up. Fan runs and engine is warm but no heat

I assume through lack of description that you are talking about the heater no heating up??

If so could be two faults.

First is faulty thermostat.

Second is faulty heater control unit / tap.

Concerning the heater problem.Sounds like you have an air pocket in the system.To remove the air pocket take off the radiator cap in the morning when the car is cold,fill radiator to top.Start the car.Turn on heater to high.Allow car to run until it gets to operating temperature.Now you will see the fluid in the radiator start to go down.This means the thermostat is opening.As fluid goes down fill radiator to top (with 50/50 antifreeze/water mix).You may have to wait a moment for it to continue to move down.Once it stops and the radiator fluid isnt going down,slowly bring up the rpm's (by either turning the throttle with your hand or have someone put their foot on the gas) to about 2000rpms and hold the rpm's there steady.As you hold the fluid will go down a little more.As it does fill to the top again and quickly put the radiator cap back on while the rpm's are steady at 2000.After the cap is correctly on release throttle.This should remove the air posket.
