Hi I have a 2005 stallion panel van ... same as condor also 2l petrol. Also had some heating issues here is my experience. It could be 1. malfunction viscose fan 2. broken thermostat 3. blocked or worn radiator 4. Water pump seal leak or corroded or loose impeller. 5. blown cylinder head gasket 6. cracked cylinder head.
In my case the water pump was leaking slowly as a result of the inner seal creating an airlock in the water system which in turn releases the pressure in the system and lowers the boiling point of your coolant.. If this is the problem you would find that with periodic checks your system will need some water. Look on top of the pump behinf the pulley is a hole which looks somewhat like a missing bolt. This hole will drip water if the inner seal has gone. Look for a telltale sign that water has run out of this hole like a sediment line from the hole down the side of the pump. If so replace the pump there is no other repair even if the rest of the pump eg bearings look and feel perfect. Just a hint for this job the radiator needs to come out and all the belts off etc. so while the coolant is out replace all the belts and thermostat. Thermostat housing is on the right side of the engine just follow the water hose. Hope this helps. Good luck. Ernest

I own a 1999 Ford Expediton and the heat nor ac is working, plus all the coolant is running out of vehicle, there is a hole in the steel hose coming from the coolant system up front, and also top where it...

this steel hose is a coolant line for the rear heat so it will be under pressure, the fix you do has to withstand this pressure so i would have it fixed properly and replace the line. Is this why heat doesnt work as the coolant leaks out?

2004 chevy 3500 van has rear heater and it works fine the front heat blows cold replaced thermostat and hot water shut off valve is there a module that opens a door for the heat if so where is at

I know on an astro van there is a heater valve under the hood on the passenger side. check the cables or vaccum lines going to the heater valve under the hood. If there is a module it will be mounted to the heater suit case under the right side of the dash

No Heat and Overheating in 1999 Chevy Silverado

After replacing the thermostat, you must bleed the air from the cooling system.

To bleed air from the 2.2L and 2.5L engines, remove the plug or sensor on the top of the thermostat housing. Fill the radiator with coolant until the coolant comes out the hole. Since the plug is made out of steel and the thermostat housing is aluminum, it is a good idea to apply an anti-seizing compound or Teflon® tape on the plug threads prior to installation. Install the plug and continue to fill the radiator. This will vent all trapped air from the engine.

Any trapped air in the heating system will have to be displaced by coolant. Once the cooling system is filled, with the radiator cap off, turn of the heater at it's highest setting. Start the engine and allow it to reach operating temp. You should see a drop in the coolant level as the air in the heating system is displaced by coolant. Add coolant to the proper level and replace the radiator cap.

Keep a close eye on the coolant level for at least the next couple of weeks. The cooling system is a "closed" system. Any significant decrease in coolant level indicates a problem.

If you have any questions, let me know.

Please take the time to rate this solution.

Drive safe and be warm.

Have very little to no heat in my 2001 venture van do you think its possible to be the head gasket or just thermostate

The thermostat is a good place to start if the only problem you are having is little heat.
Before you start removing the stat, check the following things:
-is the coolant level full?
-is there coolant leaking onto the ground?
-are the heater lines that run coolant into the cabin hot?
-is there excessive white smoke coming from the exhaust?

if the level is full and there is no leaks or white smoke, and the heater lines aren't very warm, then change the thermostat....but be careful when you fill the system back up with coolant. there is a bleeder valve on a black post on the water pump housing that needs to be opened to get the air out of the system. if your van has rear heat, which most do, the air will be harder to get out. a good trick that often works is to take the hose off of the bleeder tower and fill more coolant up there. also drive the van a about 5-10 miles and the check the coolant level. do this a few times until your heaters (front and rear) are throwing good heat.

be patient with the bleeding of these, it takes some time.
