When the thermostat and radiator were replaced, coolant could have dripped into an electrical connector or a sensor could be disconnected or damaged. Check the temperature sensor and crankshaft sensors first.

What does it mean when your surge tank boiling?

If your surge tank is boiling, it means that the coolant is reaching a temperature where it is beginning to vaporize and bubble. This can be due to issues such as overheating, low coolant levels, a faulty radiator cap, or a malfunctioning thermostat. It is important to address this promptly to prevent damage to the cooling system.


What is the correct water level for a Camry wagon radiator?

To the top of flange where the radiator cap seals. Pressurized systems overflow to the surge tank when hot and draw the coolant back into the radiator when they cool down. The surge tank has the level mark cast into the plastic. If your radiator is low,the surge tank is probably dry. Fill both to the proper level.


2000 deville cad surge tank overflow tupe drains when car is running or not when engine warms up. Engine does not run hot I replaced surge tank cap still comes out the over flow and i haven't overfill?

Replace The Radiator Cap. Sounds as If This Is The Problem. GOOD LUCK WITH THAT


Where is the thermostat for a 1997 Pontiac Sunfire?

On the passenger side of the car, trace the hose from the bottom of the radiator upwards. This hose is tapped by another hose from the coolant surge tank. Follow the hose towards the engine block. The thermostat is located at the end of this hose. There are two small screws that hold the thermostat housing to the larger housing. Apply penetrating oil to these screws if they are tight. Remember to drain the radiator of coolant before removing the thermostat housing. There is no gasket between the thermostat housing and the larger housing. When remounting the housing, use the paste that is specifically manufactured for this purpose. It is sold at any auto supply store. Remember which direction the spring of the thermostat points before you remove it.


Will the surge protector resume operation with a blown fuse?

If the fuse in a surge protector is blown it will not resume operation unless the fust is replaced.


Why will my heat pump not start when i turn on thermostat?

First, is the thermostat in he correct position for cooling? Is there a red light glowing on the thermostat? There could have been a power surge or outage and the heat pump needs to reset. Turn the power off to the heat pump at the control panel for a couple or minutes then back on again to reset the heat pump.


Where is the radiator cap on a 2002 Chevy Malibu?

the cap is on the coolant surge tank, on side by fender.


How can I tell if a water pump is bad on a ford Truck?

Wait until the thermostat opens , so the top radiator hose is hot , then squeeze the radiator hose and then stop squeezing - if the water pump is working you will feel a surge of coolant through the hose if the impeller inside the water pump is fine ( I'm assuming that there is no squealing sound or coolant leaking from the weep hole of the water pump )


How do you tell if water pump is working 1991 Crown Victoria 5.0?

I'm not a mechanic / technician but the way that I tell the water pump is working is : I wait until the engine thermostat is open ( the top radiator hose is hot ) and without catching anything in a moving belt I gently squeeze the top radiator hose and then release it slightly , you should feel a engine coolant surge


Where is the radiator cap on a 1994 Ford Probe?

It is on the passenger side of the radiater. The surge tank and cap are on the driver side


Will power surge through an air conditioning unit if the unit is turned off at thermostat?

This question is a little vague, but I'll make by best attempt. I am assuming you mean a whole-house HVAC unit, and that you are concerned with a possible power surge so you want to shut the unit off at the thermostat. If this is correct, you need to know that the thermostat doesn't control the HVAC unit the way a switch controls a light fixture. As long as your HVAC breaker is on, you will have AC power at the HVAC unit. This usually includes at least a condenser unit outside and a blower either outside or inside. All the thermostat does is tell the HVAC components when to use the power applied and when to do nothing. The power does not flow through the thermostat to the HVAC like power through a switch to a light. Think of it this way: 'Off' on the thermostat doesn't mean power off. It means 'power available, but unit not running'. So, if you want to protect your HVAC from the potential of a power surge you will have to shut off the circuit breaker(s) feeding the HVAC components, not the thermostat.
