What you've been sent is the radiator for the diesel variant - as opposed to what appears to be the 1.25l Zetec petrol engine in your first diagram. You're correct in that the "main" radiator connections are the same between the two (Despite the confusing placement of the lower hose on the second diagram it is the same hose and hooks up in the same place ...

Coolant coming out clean is a good sign. How to spot a bad radiator A radiator is a device consisting of tubes through which coolant flows and fins connecting the tubes. The fins increase the surface area of the radiator (dramatically), increasing cooling efficiency. The surface of the radiator should look uniform. If there is an area where the fins are ...

Radiator flush isn't anything magic. It is just a corrosive liquid that attacks everything in contact with it, to greater or lesser extent. You hope it dissolves the blockage before it makes a mess of anything critical like the cooling passages in the cylinder block or the inside of your water pump, or it dissolves a hole in the radiator itself. (Old ...

If the hoses are shedding rubber then they are nearing their end of life. To avoid problems, like having one burst open on the road, you should replace any of them which are showing signs of age. Being pliable is NOT a reliable test, in fact when they get old and start to deteriorate they usually get more pliable. Replacing the hoses is not that expensive ...

Run it for a bit so it mixes. Then go to a shop / garage and have the ratio tested. Once you have the result, then you can drain a bit and add water if necessary. If it is within the correct range then you are lucky. Warning do not open the cooling system when the engine is hot, always wait for it to cool down. However, it was better to add as you did, ...

Probably a couple reasons. For something to be mass manufactured and marked for human consumption, it needs to go through a certification process, needs to be stored in food-grade containers, etc. The deionized water didn't go through this process, and probably isn't in a food-grade container. Also, it may contain trace chemicals from the deionization ...

I am chemical cleaning engr. Pls. do not use vinegar to your car radiator because it is normally made of aluminum it will severely attack the material. With Citric acid is not also advisable but then possible to use under the condition that you know what to do, like the temperature during the cleaning and time of exposure, do not expose to more than an hour ...

What @blacksmith37 says is true, kinda. You could stick the hose into a catch bottle, and that would tell you that coolant is coming out during high load, high temp conditions. That's it. The coolant in that bottle WILL not go back into the radiator during cool down, like in a more modern cooling system. What makes that work in a modern flow back overflow ...

The reason the cooling fan comes on when you turn on the A/C is because in front of your radiator there is another part that looks just like a radiator called a condenser. The condenser works the same way that the radiator does in that it radiates heat to the atmosphere, and it does this more efficiently when air is moving faster through it. The scientific ...

One of the hoses could have a small pin hole and be causing the loss over time - as the coolant only escapes when fully hot and under pressure then the coolant evaporates and leaves no trace. The coolant can spray out into the engine compartment and not condense on any component or leave any trace around the hole... I found one by driving it hard when up to ...

I would look at replacing your temperature sensor, as it is telling the computer to turn on fans, But, its not keeping the fans running. Good likelyhood it is defective and there cheap 15-30$ most of the time with exceptions.

If the block heater functions you will be able to feel the heat by touching the engine after 4-5 hrs,it is not a problem to have the block heater on overnight. If you are unable to feel the heat after multiple hrs the block heater does not funcktion so it needs to be replaced or it might be a bad connection before the heating element. Here comes a pro tip ...

Most newer cars have thermostatically controlled fans. Which means fans start spinning when certain temperature is reached. To test them out just run your car at idle and wait for your car to hit over 90 degrees Celsius, keep in mind some fans start when the temperate hit 100+ degrees Celsius. To answer the question, yes, most likely you will be fine without ...

It's best to minimize the amount of air below the cap, so topping it off up to the ring that the cap seals against is best BUT if you've just replaced the coolant, there's likely to be air elsewhere in the system anyway. Some vehicles have a defined bleeding process you have to follow to get the air trapped in high points out (usually the cylinder head and ...

Possibly a blown head gasket. Did the car overheat when you started losing the ability too go over 20? If so the engine may have overheated too much and blown a head gasket (why it wont start). Any other details on the no start would be helpful.

Probably. Sulfamic acid is the material of choice to clean industrial tube heat exchangers. These units are steel and brass. I can't say if it is good with aluminum as aluminum is almost never used in refinery heat exchangers. I doubt your radiator is steel, I have never seen a steel auto radiator. Today they are generally aluminum . Older ones were copper ...

The 1259 code usually comes on because of a switch failure on the vtc solenoid assembly. You can check the screen in the gasket for blockage. Oil control valve failure on these is not as common and sets a different code IIRC. The inline trans filter wouldn’t set the code. Check the connectors for water. If they look fine. Use a scantool and do a test drive,...

Modern aluminium rads will have rust buildup that plug the rad upp, vinegar doesn't work, what you need to do is buy something like Tremans X-rost and take the radiator out plug the holes and fill it up with X-rost, let it be there for 48 hours and then clean it with water, will be like new inside.
