Peugeot 306 - Bypass heater exchange - alj

I have an old Peugeot 306, with a faulty heater exchange leaking into the passenger footwell of the car. Due to the age/value of the car, I don't want to replace the heater exchange. I'd like to simply bypass it so I can make the car last a few more months before I replace it (over the summer). Will bypassing the heater exchange temporarily solve my problem? Any major risks / downsides? Can anyone provide very simple instructions on how to bypass it?

Thanks in advance.

No problem, just pull the hoses off and join them with a piece of copper or plastic pipe.

You could try some Radweld or similar, then you would retain a working heater.

Otherwise, with a cold engine, remove the 2 heater pipes from the connectors at the bulkhead where they pass through to the heater matrix. Find a piece of copper pipe that is a tight fit into the 2 pipes & join them together. Secure these with 2 jubilee clips. Check the coolant level & recheck after the engine has reached normal temperature.

Even easier,just run one of the hoses you already have from the heater water outlet on the engine back to the return connection.
