Front crossmember bent into radiator
In January I had a full service for my 147. My cousin (the mechanic) noticed that the front crossmember is bent into the radiator slightly, indicating that a previous owner has had a front end collision (looks like they've driven into a post or something) and have not replaced the radiator and crossmember. He advised me to keep checking the levels and not too worry if it doesn't seem to be getting too low. However I've had to top it up since then, (it goes from max to min after about 6 weeks).
So what course of action do you recommend? It's seems to be either live with it and keep topping up, buy a new radiator and crossmeber, buy a second-hand radiator and crossmember, or use something like Radweld or an epoxy resin. I've never had any experience with the latter two additives. I know that some people swear by the likes of them, others adamantly avoid them. Does anyone have any experience of them? Any recommendations?
Thanks in advance.
