What if coolant leaks when car is parked and radiator still has fluid where and why would it be leaking also what if you can smell it through the car while driving with out heat or AC on?

HOW TO DRAIN and refill COOLANT from a system which doesn't have radiator cap Would the coolant reach the radiator is we refill the coolant through the coolant header tank?

In systems that do not have a radiator cap, the coolant is drained by the radiator drain plug. It is filled by adding coolant to the system through the overflow bottle.

What does the radiator in a car do?

As coolant cycles through the engine, it absorbs heat from the engine, after which, it continues through the cooling system back to the radiator. As the coolant passes through the radiator, the heat is exchanged to the ambient air by way of airflow through the radiator fins (this is why it's important not to bend the radiator fins).

What is the cause of Chevy Tahoe 95 oil is going through engine coolant?

Does it have 2 lines coming from the top of the oil filter, and going to the radiator. If so that is the oil cooler. You need to replace the RADIATOR Those 2 lines go into the radiator so it can cool the oil, and the tubes are leaking oil into the coolant.

What can cause a car to lose coolant?

Lots of possibilities. Here's what I can think up in a few minutes. Is the liquid visibly leaking out or just disappearing? Does it come out in bunches or in drips that show up on your garage floor? The radiator could leak through a seam, or due to corrosion in the main core. The heater core could be leaking. Leaking hoses. This could be the main radiator hoses, or the two that go to the heater core. It could also be a leak out of the overflow tank or the line that runs to it. Leaking freeze plugs. These corrode with time, especially if you don't flush and fill your radiator regularly. Is it regularly overheating? Maybe the coolant is just boiling off and escaping through the overflow tank, assuming you have one. Then there's bad stuff. Leaking head gaskets allow the coolant to enter the combustion chamber or the crankcase. And really bad stuff. Your head or block are cracked and the coolant is leaking into one of the places above. SEVERAL THINGS. A HOLE IN A HOSE TO THE RADIATOR FOR ONE a hole in a heater hose or radiator hose a leaking radiator a leaking intake manifold a leaking cylinder head a leaking heater core if there is any coolant on the ground then it should be easy to see the leak. if there is coolant loss and you can not see it, there might be a internal problem (cylinder head gasket) or the coolant is evaporitating before it hits the ground. pull the oil cap off, if it looks like you spit on the cap then its coolant in the oil. you might want to try and run the vehicle and see if you see any blue smoke coming from the exhaust, if so its probaibly a head gasket. i need more information to help you diagnose the problem correctly (year, vehicle, engine size, etc.)

Why is there a reddish substance with a low viscosity leaking out of your radiator?

It could be transmission fluid. Many transmissions are cooled by running a line through the radiator. Check for small tubes going into the radiator, if you only have the two large engine coolant lines, you don't have a transmission cooling line in the radiator.

What is a car radiator?

A storage tank for the engine coolant. Air flows through the radiator helping to keep the coolant cool.

How do you diagnose a radiator leak?

First I eye-ball the radiator and all coolant related parts then if the leak isn't obvious I pump 15 psi of air pressure into the cooling system with a cooling system pressure pump. This usually helps locate the source of the leak.

What controls the coolant flow through a radiator?

the thermostat

What could cause oil in your coolant resivoir but no coolant in oil in a new engine in 2001 ford lightning?

Check your transmission fluid, The cooler that runs through the radiator may be leaking into the cooling system. If so, the radiator will need to be replaced, and possible transmission will need to be flushed as well. Good Luck!

Why is oil in coolant bottle?

Does it have a oil cooler on the engine ?? If it does then oil runs through tubes that are inside of the radiator to cool the oil, and the tubes are leaking oil into the engine coolant. REPLACE RADIATOR. Really need to know what you are working on. Engine size and year. It could verywell be something else. Let us know NEUTZ.

The coolant flow through the radiator is controlled by the?

The thermostat.

Where is the radiator cap in a 2004 avalanche?

There is no radiator cap, you must fill through the coolant reservoir.
