Left hand side of engine compartment. It is the cap on top of the round tank towards the back. The front one is the washer tank. It is a good idea to use antifreeze mixture so you do not dilute the stuff in the engine. DO NOT REMOVE CAP WHEN ENGINE IS HOT!!!!!
how do u change the timing belt in my 307
Antifreeze G12+, G12 or G11
If no reservoir, have you checked the side of the raditor for a filling point? probably there same as an old 306
you replace lost coolant through the expansion tank located at the back of the engine bay but only when cold
You don't put water in your radiator, you put antifreeze.
No. Let it cool down before you open the radiator cap and then put water in the radiator
If you are having an issue with the immobilizer on a Peugeot 307 HDI, you need to recode your key. To do this put the key into the ignition and turn to the on position, hold the Lock button on the key for 10 seconds, take the key out of the ignition, and then test to see if the car starts after another 10 seconds.
Water
Look at http://www.radio-code.co.uk/clarion-c181.html It's not a DIYj ob
When a car is hot, keep the car running and add water to the radiator. When a car is cold, you can simply put the water into the radiator.
You can put ice in your radiator. Keep in mind that the ice is just water and you should have SAE certified anti-freeze in your radiator
There is a white plastic bottle next to the radiator cap. This is where you put the water. there is a mark saying full . if you go beyond this by mistake it wont do any harm in my experience. the water is sucked from this into the radiator.
