Not the most technical or interesting of question I know,:whistling:

But can I leave Wynn's rad flush in for a couple of weeks? or am I in danger of corrosion and also damaging gaskets etc':nuke:

Thanks in advance,

looks like i need to get a spray gun and a sticky window?:lol::lol::lol::lol:

ive left it in before on the wifes car, didnt have any problems

i also used it on my mrs rover 75 when i flushed all the crap out of that when i changed the thermostat it was in it for 8 months before we sold it and it was absaloutly fine!, being honest i dont think it did that much and i used 2 bottles!

Personally I would change coolant after the Wynn's done its job. You never know if you have an old gasket or pipe want to give up.
