How to get the top radiator hose to be hot?
1 Remove the splash tray and push the coolant catch tray in. 2 Remove the thermostat cap, usually on the top hose at the engine. 3 Clean the stat seat on the engine and cap. 4 Lube the new stat seal with fresh coolant and fit it, check the orientation (Jiggle valve up). 5 Tighten down the cap bolts and torque to approx 10Nm (89in lbs).
Why does upper radiator hose keep building up pressure?
Q: Upper radiator hose keeps building up a lot of pressure and popping off. Car loses coolant and over heats. My upper radiator hose keeps building alit of pressure and popping off and car loses coolant and overheats. I changed radiator cap after reading that could be problem. My car has 191400 miles. Hello, thank you for writing in.
What should I do if my radiator hose Pops?
Clamps on radiator hoses often get changed. As old as our cars a getting, most have been through at least 2 or 3 previous owners hands. Don’t be surprised to find that your clamps aren’t the stock ones. If you’re going to use metal worm clamps, I’d suggest looking into heavy duty ones.
Why is my radiator hose warm after a cold start?
If the top and bottom radiator hose are equally warm after a cold start. The thermostat is likely stuck in the open position. John Cunningham is an Automotive Technician and writer on Rustyautos.com.

What should I do if my radiator is leaking coolant?
You will want to inspect both sides of the problem hose, and determine if the clamp is doing its job. Considering it is the top hose, the coolant is coming from the thermostat and flowing down through the radiator to be cooled.
Why is coolant building up on my radiator?
Typically it is because the hose or the plastic neck that connects it to the radiator/component has failed. You will want to inspect both sides of the problem hose, and determine if the clamp is doing its job. Considering it is the top hose, the coolant is coming from the thermostat and flowing down through the radiator to be cooled.
Where are the hoses in the fuel system?
In addition to the hoses shown above, TBIRD9491 mentioned some other hoses in the fuel system that may need replacement. There is one hose in front of the fuel filter (you may need to loosen the fuel filter bracket and pull it down slightly to make it easier to access), there is one hose behind the fuel filter]
Can a 5 / 8 ” emission hose be replaced?
If they had 5/8″ emission hose I would have used that. Due to the oil/fuel vapor that may come in contact with the hose, the hose may break down sooner than the OEM hose, so it will have to be replaced sooner than the other hoses/lines. Again, this is a cheap fix so it’s OK here 🙂 Here’s a photo of the drivers side rotten hose:
How big is a fuel line and heater hose?
1/4″ fuel line / vacuum hose (2 ft) 3/8″ fuel hose (1 ft) 5/8″ heater hose (1 ft) So I went to the local auto parts store for the stuff, but the total for those parts was a bit less (they sell hose by the foot even though you won’t use it all just buy what the amounts I mentioned).
What does the thermostat on a radiator do?
The thermostat has a special function within the circuit, it’s job is to restrict coolant flow back to the radiator when coolant temperature is below 180 deg F (83 deg C). Above this temperature a wax filled cylinder within the stat melts and expands causing the valve to open proportionally until fully open at about 199 deg F (93 deg C).
Is the water pump still hot after replacing the radiator?
I have replaced the radiator, water pump, it still run hot. I took out the thermostat and it still run hot when you drive it any distance. The temperature gauge return to normal when it is setting still and running. Help I’m at a lost to the problem. 71 people found this helpful. Did you ever find the cause of this?
Can a defective radiator cap cause engine to overheat?
A defective radiator cap will cause engine overheating in a number of ways. Three of the ways a radiator cap can cause overheating are, 1) Not holding in pressure and allowing the coolant to vent out or escape the cooling system. 2) No providing the proper pressure and not raising the boiling point.
What happens if a radiator hose collapses on a car?
A collapsing radiator hose will prevent coolant from moving through your cooling system and will quickly cause engine overheating. A spring or coil is added inside some hoses to prevent the hose from collapsing and shutting off the coolant flow. Check all your hoses and make sure none are collapsed or sucked shut.

Can a thermostat cause an engine to overheat?
A thermostat can cause engine overheating in many ways. It can be stuck shut, it can be stuck open, it can be partially open, it could be opening at the wrong temperature and it could just come apart and be broken. If you are overheating always check your thermostat, as it is one of the top causes of overheating.
What causes the lower radiator hose to get cold?
Thus, making the lower radiator hose to heat up. It may happen that your car might get low on coolant and is not able to reach the lower radiator. As a result, the lower hose emits cold air. 2. Water Leaks The most common problem that is guilty of this issue is the water leaks. There are several places responsible for these leaks.
Is the bottom of the radiator hot or cold?
It may take up to 30 seconds for the thermostat to react and partially close, restricting the flow of coolant from the radiator into the engine. The bottom radiator hose should be cold, or maybe warm on very hot days.
Is the bottom hose of an Audi hot or cold?
The car in question I a Audi 1.9 tdi. When you drive the car the temp rises and rises. The top hose is hot/pressurised but the bottom hose is stone cold. Thermostat has bern changed but the problem persists.
Why is my radiator cold at the top/bottom?
A radiator that’s cold at the bottom and hot at the top is usually because of the build-up of sludge, a black, mud-like substance which is a byproduct of corrosion inside the system. It can seriously impact a radiator’s effectiveness, resulting in a chilly, uncomfortable room.
Is it possible to clog a radiator hose?
If the radiator is blocked, the coolant will not flow evenly. Another quick way to check for a clogged radiator is to ask someone to rev the engine while you are squeezing the radiator hose. If the radiator hose stiffens and is difficult to squeeze as the speed of the engine increases, this means that the radiator is clogged.
Why is my top radiator hose collapse?
If the vacuum valve in the radiator cap fails, the resulting vacuum in the cooling system can cause a radiator hose to collapse. A malfunctioning radiator cap can also constrict coolant flow.
What are the causes of a swelling radiator hose?
- Excessive Pressure. Coolant systems are designed to operate under pressure. The pressure moves the coolant through the engine and cycles it through the radiator.
- Wear. Radiator hoses are under constant pressure.
- it creates a chain of events.
What to do if top radiator is overheating?
Remove the splash tray and push the coolant catch tray in. Remove the thermostat cap, usually on the top hose at the engine. Note the stat’s orientation, it is possible in most cases to fit it back-ways, which causes an overheating condition. Clean the stat seat on the engine and cap.
What causes a car to overheat with a new thermostat?
A leaky head gasket or a cracked cylinder head are normally due to expansion and contraction of engine materials along with high pressures caused by excessive overheating. The Integrity of the system cooling system is compromised if there is a leaky head gasket or cracked cylinder head.
Why is my car overheating after replacing the radiator?
Overheating. Just replaced radiator and thermostat, but still hasn’t fixed the problem. My car overheated the other day, and it was leaking coolant horribly. I got a new radiator, which stopped the leaking, but the car was still overheating so then we tried replacing the thermostat but it is overheating even now.
Why is my water pump and thermostat not working?
The radiator, water pump, and thermostat are definite possibilities, but there are a few others that are possible also. A faulty cooling fan is the first thing that comes to mind, but it could also be a head gasket issue, clogged coolant passages inside the engine, or faulty radiator hoses.
Why is my new water pump still overheating?
Replaced water pump, radiator and thermostat car is still… Q: Replaced water pump, radiator and thermostat car is still overheating. What can it be? Changed water pump, radiator and thermostat. Car still overheating it has a leak in the headers and i am getting that replaced too.
