Anyone got any opinions on it? My cooling system is rusty as fook now I'm not sure wheather to use this or not as its an old car I'm slightly worried that there may be bits of rust preventing leaks etc..!

Any thoughts appreciated!

i used this b4, but it was called holts rad flush then, wasnt long ago actually i thin they have changed the name quite recently.

neway it worked well on my car, try to clean ur waher bottle out aswell that helps.

Ah okay yeah iv flushed it with water, and tbh being an old car I think it be best to leave it incase the rust is holding it together lol

Ok i have been advised not to use this on an old car as its likely to remove deposits which could be preventing leaks! Ill give the expansion tank a flush with it though.

Cillit Bang is your friend or dish washer for the expansion bottle

From the moment I picked up your book until I laid it down, I was convulsed with laughter. Some day I intend reading it.

Boiling water with a dishwasher tablet did bugger all!

I'll stick a bit of speed flush in the expansion tank and see if that works but I'm not going to put it in my system after what people have said

Thanks for your advice anyway!
