leaking radiator

Hi All,
i'm dasso0010 new to forum and looking for advice. Just become owner of range rover 4.6 hse auto 1997 with autogas lpg conversion.
Previous owner had it serviced in august they highlighted slight leak on radiator and tight viscous unit.
would it be an idea to try kseal before fitting new rad.
at moment topping up daily.
can anyone advise.

Hi
K seal in my opinion is brilliant, and for £9.40 + Del. if it doesnt fix your rad. it will certainly fix any leaking 'o'rings you might get in the future. Fixed mine. Presuming the rad leak is not major, i'm sure k seal will do the job, heres the link:

Tightness of the viscous unit may be due to water ingress causing a lot of rust inside the unit. See what the viscous is like when warm.
Hope this helps

Hi Marmite,
Many Thanks for reply and advice, I have found a couple of water hoses off the lpg a bit loose and leaking have tightened them and if still loosing coolant will try K Seal.
Again many thanks
