You can physically see the valve move back and forth when its actuated. Old Folklore, did you sort the P1110 out? I hope this was helpful. When the engine warms up, the wax melts, expands and pushes the valve open, allowing coolant to flow through the radiator. Do this by either disconnecting both heater hoses from the heater necks on the cowl and attaching spare hoses, or by disconnecting both heater hoses at the engine. Step 1: Remove the radiator and coolant reservoir caps. Hence I think that if we can sort out the P1654 then perhaps all the others will go away too.
The selection of raw materials for high product standards, modern production, the use of auxiliary equipment as well as packaging occurs with due care and attention to reasonable economic and ecological principles. Check the top radiator hose when the car is warming up, is it hot? Step 2: Start the engine and check for leaks. A swing check valve uses a disc inside it to prevent reverse flow in a hydronic loop and inside the swing check valve there are single discs and other swing check valves have two discs. The coolant reservoir was depleted. I have had the coolant temperature sensor replaced, and coolant system purged and new coolant put throughout. Check the temperature with a thermometer inserted into the driver's and passenger's registers.
Pinch the coolant hoses with 30 07 739 Hose pinch-off pliers. Also, in summer it is never an issue. Any change in the temperature at the sensor bulb causes a change in the position of the plug and thus increases or reduces the flow. The radiator is linked to the engine by rubber hoses, and has a top and bottom tank connected by a core a bank of many fine tubes. Step 8: Reattach the vacuum lines and electrical harness, if applicable. Place a container under the car. Spin it by hand with the engine off but warmed up.
Frequently a duct runs all around the fins, and an engine-driven fan blows air through the duct to take heat away from the fins. Copyright Notice: Sanitary and heating systems from Viega are recognized branded products: product quality with system warranty. Step 6: Let the engine cool and recheck the fluid level. Make sure to drive the vehicle until you hear the radiator fan come on. Zone valves allow the hydronic loop to be divided into zones for heating various areas of the structure. Step 3: Verify that no warning lights are lit.
Open the expansion tank cap and release any overpressure. Step 7: Install the new coolant vacuum valve switch. Air-cooled engine cooling systems In an air-cooled engine, the block and cylinder head are made with deep fins on the outside. Once embarked on your morning commute, you turn the heater control up to Hot and flip the blower switch. At this point the valve should slide upward out of a bracket that is attached to, I believe, the hoses behind the valve.
If the valve is cable controlled, you should see the valve shaft move continuously as the dashboard temperature lever is operated. The climate controls are typically attached to a vacuum hose which is also connected to the coolant vacuum valve. If it's good, check the valve itself for proper operation. The individual companies of the Viega group are separate and independent legal entities and as such act independently. This is a signal that the thermostat is working and that coolant is circulating through the entire system. Although many vehicles deliver a toasty 135° to 155°, 115° to 120° is acceptable. This component is typically located on top of the engine with one end screwing into the intake manifold, designed to monitor the temperature of the coolant.
If you're experiencing overheating issues or the heater in your vehicle is not working, it may also be contributed to the coolant vacuum valve switch or vacuum lines attached to this system. I pulled over, opened the hood and saw leaking coolant being boiled away into the smoke that stopped me. Heater control valves take many forms but basically they all do the same thing; they open to allow heated engine coolant to circulate through the heater core or they close to stop the coolant from flowing. It is easy to access. Triple duty valves are usually constructed of heavy duty cast iron and installed in the hydronic near the pumps. You will need a pair of needle-nosed pliers for this, but I would suggest that you get the ones that have a bent beak, or else it may take you significantly longer amount of time to loosen up the pressure clips that hold the hoses.
As indicated earlier in this article, if you're not 100% confident in your ability to complete this task, don't worry. If you notice the coolant level is low and the heater is not working correctly, this is most likely due to a cracked coolant vacuum valve switch. It may be located on the inlet or the outlet port of the heater core, and activated by a cable, electronic control or a vacuum signal. If you trace your hands to the back, past the 4 vacuum hoses, you will see it - it's cyl … indrical with a 3 fat hoses coming out of the side of the shaft below the cylindrical head. This type of system uses a blend door to mix cooled and heated air to achieve a desired temperature. If nothing applies, do an underhood inspection.
