"Peugeot 206 1.9D Radiator Leaks: Use Radiator Seal"

Peugeot 206 1.9D Engine View

Hi, well my Peugeot 206 1.9D radiator leaks all over the road the over day. I used some radiator seal which seems to have sorted it but I’m gonna order a new one to be safe. Thing is I can’t afford to get the work done so I’m thinking of doing it my self. I’m guessing it’s a bit like a radiator in your house where you just drain the system, flush it out, put the new one in, fill it up and bleed the air out. Any advice on this job would be very handy.

Answer: If you refilled with anti-freeze, drain it into a container and contact a local garage or dealership to find out where to legally dispose of it. Dumping it down the drain or pouring it into the woods will cause environmental damage somewhere down the line. Anti-freeze is toxic to animals.
Flush the system before removing anything. Do yourself a favor and inspect the radiator and heater hoses for wear damage. This would be a really good time to change them out! Also, don’t re-use your old hose clamps, spring for new.
Start by removing the hoses and transmission cooler lines (if this has an automatic). Plug the transmission lines and catch any fluid that drains from the cooler. Then, remove the cooling fan and fan shroud. Usually, the shroud bolts are all that holds the radiator down into its groove. You should be able to lift it out, now. Be careful not to lose the rubber mounts! Replacement is in the opposite order. Remember to fill the cooling system with at least a 50/50 mix, no more than a 70/30 mix. And, in case of an automatic transmission, be sure to top off the fluid level.
