Is the lower radiator hose cold or hot?
After the engine has warmed up (as warm as it is going to get), the upper radiator hose is hot, the heater core hoses are hot, the little bypass hose is hot, the lower radiator hose is cold/barely warm. Coolant level is fine.
Why is the Vauxhall Corsa heater blowing out cold air?
The problem with the heater on the Vauxhall Corsa (as well as the Renault Clio) is often that there is no power from the heaters at all. This issue has nothing to do with cold air coming out instead of heat. This loss of power is also a common issue on the Renault Clio. Or you may have a dirty fan that is stuck.
Why is the bottom of the radiator warmer than the top?
The bottom radiator hose is a lot warmer now (which indicates the radiator is not plugged and the pump is circulating coolant), but engine temp is even colder than before. I can also now see the coolant churning up in the top of the radiator, with the cap off. When I turn the heater on, the engine temp will drop a little bit too.
Why is my car heater not getting coolant?
A car that is not getting coolant will heat up and damage itself permanently. If it leaks water, you need to find the source. It can be a split hose, leaky radiator, the water pump, or even worse, the head gasket.
What’s the problem with my 2000 Cavalier heater?
My 2000 cavalier is loosing some serious coolant. There is no sign of external leakage and I’ve checked the oil and it’s normal. There isn’t any smoke either. Where is it going. I’m also loosing power and it’s getting hard to start. The heater blows hot on and off, the thermostat has been replaced and the temp. gauge is on red and fluctuates.
Why does my Cavalier 2.0 liter fan run at 190?
2000 Cavalier 2.0 Liter . Started loosing coolant. Pressure tesed no leaks. Found system pushing coolant out of overflow hose like a garden hose. Replaced thermostat, same problem. Fan runs @ 190 OK. I can only think there is a restricition in the system causing the backup.
Why is my Cavalier 2.2 leaking coolant?
There is a leak due to corrosion in an elbow in the coolant system in my son’s 2002 Cavalier 2.2. The upper radiator hose connects to the elbow, which goes into the engine (block?).
Where is the bleed screw on a Cavalier?
It sounds like you may have air trapped in the cooling system. The Cavalier has a bleed screw located on the high part of the metal coolant pipe in the front of the engine. From: 2carpros.com forum… “Always bleed air from cooling system after replacing coolant. Set heater for maximum heat. Remove radiator cap.
How is a cabin heater similar to a radiator?
Cabin heater core – The Core is not unlike a radiator, it’s used to transfer engine heat to the cabin. The heater fan blows air across the core to demist the windshield and/or warn occupants. Thermostat – Used to regulate coolant flow around the engine. The stat remains closed until about 180 deg F, this helps the engine warm up quickly.
Why does my lower radiator not heat up properly?
The most common problem that is guilty of this issue is the water leaks. There are several places responsible for these leaks. So, make sure that you check both the upper and lower hoses for any damage. If any leak persists, the lower radiator hose will not heat up properly. 3. Thermostats not Working Properly
Where are the lower and upper radiator hoses located?
From the bottom of the radiator, is the lower radiator hose that is directed to the water pump. Powered by the vehicle’s water pump, the engine coolant loses its heat after passing through the radiator. Both the upper and lower radiator hoses are the largest hoses in the cooling system connected to the engine.
Why is my lower radiator hose Cold instead of hot?
If you have a problem with your coolant temperature and realize that the lower radiator hose is cold instead of hot, you could be experiencing problems with the coolant system that needs to get fixed. You will need to look at the various parts that influence the radiator temperature to properly diagnose a lower radiator hose cold problem.
How many radiator hose heaters are left in stock?
Only 18 left in stock (more on the way). . Only 6 left in stock – order soon. . Only 9 left in stock (more on the way). . Only 6 left in stock – order soon.
Why are radiator and heater hoses made of rubber?
It’s the only means of transportation throughout the engine used to transfer fluid to keep the engine cool and some, to warm the air, to keep passengers warm in the winter. Over time car radiator hoses and other vital hoses, which are mostly made of rubber, begin to break down from dry air, heat, and use.
Why are the hoses to the heater core cold?
But it sounds like a bunged up heater core…..or a massive air pocket blocking coolant flow into the heater core. With the engine cold and you’ve got reasonable access to safely disconnect your heater core hoses one at a time, disconnect one or the other and have a friend start the engine.
What to do if heater core is air locked?
I’d personally try to find the heater core return hose and disconnect it at the engine. Start the engine and look for coolant flow. Have the friend shut down the engine after you see some reasonable coolant flow. It’s a messy method, but it’s usually effective in purging trapped air if the heater core is air locked.
After the engine has warmed up (as warm as it is going to get), the upper radiator hose is hot, the heater core hoses are hot, the little bypass hose is hot, the lower radiator hose is cold/barely warm. Coolant level is fine.
How are the radiator and heater hoses connected?
Radiator hoses are connected to both the radiator and engine to direct coolant to the radiator so it can be cooled and then back into the engine so it can maintain a certain temperature, preventing overheating. Heater hoses are used to transfer heated coolant into the vehicle’s heating unit or heater core.
What should I do if my heater core is too hot?
Set the heater to the MAX heat position. Check the temperature of the heater core hoses: Both hoses should be too hot to hold. Typically, the inlet hose should be about 20 degrees warmer than the outlet hose. If the outlet heater hose is significantly cooler than the inlet hose, the heater core is probably clogged.
When is the top of the radiator supposed to be hot?
Either-way, the top hose gets hot after the thermostat has opened. The time the thermostat takes to open depends upon factors such as: In this post you’ll learn how the coolant system works, when the top hose should get hot and what you should do if it doesn’t. The coolant system after the oil system is the next most critical system.
Radiator hoses are connected to both the radiator and engine to direct coolant to the radiator so it can be cooled and then back into the engine so it can maintain a certain temperature, preventing overheating. Heater hoses are used to transfer heated coolant into the vehicle’s heating unit or heater core.
Why is only one hose goes to the heater core?
It also helps to turn the heater on high without the fan and also to raise the front end of the vehicle to help with moving the coolant through the engine. Repeatedly squeezing the rad hose also helps to push out air. Hope this helps Was this answer helpful?
What does it mean when your car coolant hose is cold?
The engine needs to be really hot and almost overheat before the thermostat lets the coolant pass by. If your car is not overheating, but the lower coolant hose is cold when you feel it – it may just mean that it is not hot enough, and therefore there is nothing wrong with your engine.
But it sounds like a bunged up heater core…..or a massive air pocket blocking coolant flow into the heater core. With the engine cold and you’ve got reasonable access to safely disconnect your heater core hoses one at a time, disconnect one or the other and have a friend start the engine.
How much does it cost to replace a radiator hose?
Coolant Hose Replacement Costs Radiator hose replacement costs and heater hose replacement costs can range between $150 and $450 with heater hoses on the lower side while coolant hoses are a bit more costly.
