Wickes thermostatic radiator valve will not open

Domestic heating Wickes Radiator Valve will not open. I can remove the dial part of the valve and the central pin is stuck internally. The external part of the pin moves, but the spring is not opening the valve. Any suggestions without emptying water from the system. The valve has been closed for the summer months, and it is stuck in the closed position, usually a gental tap will release it, but one is stubborn. Any suggestions?

Have someone do a Block test of the cooling system to determine if you have a headgasket problem seems likely that that is your problem, or pull the plugs connect a cooling system pressure tester and pump ot up to 20 psi or more and leave it there if it drops pump it up again, leave it there for an hour or so and keep looking into the cylinders for evidence of coolant if you see any you have a head gasket problem.

make sure you bleed the air out of the system on the top left hand side of the radiator or the car will overheat due to air lock

SOURCE: 96 suzuki vitara - radiator empties but no visible leak

Check the passanger side floor board for moisture this could indicate a bad heater core. Then I would check the engine oil and make sure its not milky looking (head gasket). make sure when you fill it let it run with the cap open with you looking into the cap to be sure is circulating and not vapor locked (air pocket)
hope this helps

SOURCE: 1995 Nissan Maxima Over heating, no heat blowing, water not moving

Simple thing to test first would be to pressure check the radiator cap. Next would be to check for combustion gases in the radiator indicating a leaking head gasket.  It is an aluminum head and iron block engine and there is a possibility that antifreeze anti corrosionpackage runs out due to over age then fails due to too long in the engine it results in galvanic corrosion at the head gasket-commonly resulting in a failed head gasket.  There are other engines that are vastly more prone to this than the maxima engine.  If there is a leaking head gasket the gases could rise to the top of the system and block the water flow into the heater.  Listen for gurgling sound in the heater.

SOURCE: Help with cooling system!!

OK, firstly The basis that a cars cooling system runs on is very simple. The system is a pressurized cycle that moves the coolant around, along with the heat, and is slowest in the radiator to allow heat to escape. If the system is not pressurized then the cycle will not work properly and coolant will not move.
If there is air in the system this can create what would seem like a blockage. 'bleeding the system is not the answer especially if you are using the drain on the radiator. That drain is only for draining fluid not air.
If air blockage is the problem then what you do is open the system at the highest point possible. this is usually a hose at the top of the radiator or something, whatever is easiest. Then find the other hose attached to the radiator, lower, higher makes no difference. then simply squeeze the second hose. this will 'burp' the air out do this for a while until all that happens is fliud is pushed out repeatedly.
then reattach the top hose and top up the radiator, and go for a drive.
If this doesn't fix the problem then air is not the problem.

What is mean by thermostate valve


The thermostat is a critical part of your coolant system, the system that circulates water and antifreeze (coolant) through the engine to keep it from over-heating. It is called a valve because it can open and close, depending on how hot the coolant is acting upon it.
The reason to put a thermostat in the coolant system is to allow the engine to reach normal operating temperature quicker (and therefore operate at peak efficiency) than without a thermostat.
When the engine is cold, the coolant is at normal outside temperature, so the thermostat is closed. This means when you start the car, the coolant starts circulating through the engine, but can't flow into the radiator. With a closed thermostat, the coolant just keeps circulating around in the engine until the car warms up, the coolant gets hot, and the heat acts upon the thermostat, causing it to open at a certain temperature (about 185-195 degrees F.), With the thermostat now open, the coolant can now enter the upper radiatior hose and flow down the radiator to cool itself down, before going back into the engine through the lower radiator hose.
So the thermostat is always found on a car in the area where the upper radiator hose connects to the engine. Thermostat closed-water can't circulate through the radiator. Thermostat open- coolant is forced through the hose into the radiator.
I hope this helps you understand the thermostat valve and why all manufacturers include them.

I have a 1994 Jeep wrangler 6 cylinder. I replaced the cooland and therostat and it opens like it should at about 100 but the air is still cold. Is there something I overlooked?


Hello! Thermostat should be a 190 degree...you may have an air blockage...Remove radiator cap start engine and leave cap of until all air bubbles are out (even after thermostat opens)...Cap and test for heat...if there isn't any heat...When that thermostat opens and hot water flows through the upper hose of the radiator that hose will be hot and hard..If you feel the heater hose only one will be hot which means that nice hot water is not passing through the heater core...That could be due to blockage or the control in the car isn't opening the valve on the core...check to see if the heat control is opening the valve...If it is, I would suggest that you purchase a back flushing kit ($10) A plastic tee fits into the inlet heater hose and a garden hose is then connected to the tee...Drain the radiator, remove the thermostat, and turn on the water...do this with heat control on high...The system will back flush out of the top of the radiator and hopefully clean the blockage...Reassemble ...Cap off the tee (cap is in kit)...Install thermostat (190) Is a better choice...Refill radiator...Start engine and leave the radiator cap off until all the air bubbles out............At that point you should have heat...Guru...Saailer

Heat is luke warm and coolant temp gauge not getting to operating tempature. installed a new thermostat with the valve up on the thermostat. removed the heater control valve to make sure it was functioning...


this is probibly a blockage in the radiator or water pump issue start by flushing the radiator,then check that water is flowing thru the radiator and water system.

The heat in my 93 talon dont work. the fan blows, and i have flushed the heater core. still no heat. it is getting cold in kentucky. please help.


If you have flushed the heater, I assume you did this by removing the hoses from the thermostat housing. If there's still no heat, check

1. the thermostat is actually present. If not, put one in. If the radiator core is in bad shape, or blocked, replace the radiator.

2. the thermostat is not jammed open. If so, replace it and use a new gasket under the cap.

3. Verify that the water pump belt is not loose.

4. Remove some dash panels to get access to the heater core valve. Check that the valve is actually turning when you adjust the dash control.

Heat blows cold, where is the thermostat to change it


Follow the lower radiator hose, it ends at the thermostat when you are done, be sure to bleed the air out of the cooling system. Fill it up and open the bleeder valve at the thermostat housing (12mm) fill the radiator until coolant comes out of it, then tighten it and fill the radiator up. Does the engine temp read cold also? The heater valve is located down low on the firewall with a heater hose going to it, be sure its operating with your temp cable.

How to remove the thermostat


Remove cap radiator when cold
Drain radiator well below thermostat level.
Disconnect rubberhose from thermostat housing to radiator. Do this at radiator side first cautious to prevent blocked fluid to run over engine . Undo radiator housing cover. Be sure to have new spare gasket. And right type new thermostat with corresponding temperature opening rating.
Take out thermostat. Put new one in in the good position not reversed down (it opens at temperaturing pupping upwards. Check for presence of de-airation hole with little valve.
Put gasket and cover . Tighten the bolts without killing them. Fill radiator to level. Leave a while do de-air leveling over that little hole valve in thermostat I mentioned. I necessarry fill again.

Whilst doing this job be sure the seizure of old thermostat was not due to broken down cooling pump, broken radior fan with activating switch on engine block. At times they go together.

Don't fill with pure water unless for backflushing system. Otherwise vapor bellows in th system will crack the engine block. Some hotspots exceed water vapor point!!
