I fear you have been foolish. The K series engine has small water ways, so radweld may narrow them down, unlikely tho. Now its in, you'd be best off getting the coolant hot so its circulated around rather than just sitting in one place imo.

 

I would only use it as a short term measure but it is unlikely to cause any damage, on the bottle it states not to use on Rover 825/827 models but otherwise no restrictions.

I used it once is a Peugeot 106 that had a very slight coolant drop yet no sign of a leak, the radweld product cured the leak and the car performed fine for many 1000's of miles after until it was sold.

 

You need to get the coolant system flushed out ASAP (if not sooner), Radweld is a k-series killer.

 

:rofl: sooner than as soon as possible :lol:

well I thought it was funny.....

 

Yep, you've done a foolish thing. But at least you've provided an exampe to others who might do the same :broon:

 

how do i flush the coolant system ????????????????

 

Take it all to bits, all pipes off and flush it out with a hosepipe.

Nasty job.

 

noooooooooooooooooooooooooooooooooooooooooo

 

crap end to a crap week ahh well i give up stuff it

 

I still say you will be fine in the short term, radweld will only seal tiny holes so its unlikely (in my opinion!) to block any of the engines waterways. Your cooling system fluid will not clear though, it will stay that colour until you flush it out and refill.

 

My understanding is that Radweld will react with air and solidify...........ie at a leak. No air...should just circulate, but I suspect in time will cling to inner wall of pipes, so get it out asap eh?

 

i'll say one thing ,i have'nt seen any drips from the radiator since

 

haha :lol: I guess it has worked then! :dddc:

 

how did you get on with this? did you drain all the coolant off?

 

i have 'nt done anything other than keep my fingers crossed so far no more drips and over flow bottle starting to clear up

 

Does anyone have any solid evidence about the negative effects of sealers? I have taken the heads off a couple of engines which have used the stuff and not seen any evidence in the coolant passages at all. If it blocks small passages, I would expect it to seal up the radiator matrix, but it obviously does not.

As I understand it, sealers either work by blocking tiny holes with microscopic fibers, or they set hard when exposed to heat and air.

 

should i chance it or still get it flushed out ?

 

I would leave it unless you notice any problems.

 

does the expansion tank still look like its had hgf?

 

it does'nt look as bad as it first did ,it now just looks like it has got a slight bit of grease [film] on top of the surface

 

one post says its a k series killer! id take it in and have it flushed out nice new coolant put in. your call mate.

 

there is one problem tho underneath the bonnet on the right hand side is a bleed nut which i disturbed and is now seeping slightly could do with sealing it up again but how ?

 

You could try Radweld?

(Only joking...please read my disclaimer)

 

if i take the bleed nut out is it gonna pour out of coolant will it cause air blocks

 

if i take the bleed nut out is it gonna pour out (NO, it might if it's hot, let it cool down 1st ) of coolant will it cause air blocks ''YES''

if that helps?

Ps taking the rad cap off when it's cold could take some of the pressure out of it.

 

It will come out, but not pour out. Keep cap on expansion tank to keep negative pressure. Block rad bleed valve with somehting whilst you put the tape on and then bung it back in.

If you are that worried, jack up the front of the car as well
