K SEAL ADDITIVE

mikelamb · Post by **mikelamb** » Sun Mar 22, 2009 10:28 pm

Hi All,
Would really like your thoughts on this one.
I recently added a can of K seal to the water system on my Bongo. I did it as a preventetive measure as it says that it stays in the system and blocks holes that appear in metal pipes ect. After adding it I have noticed that the mason alarm comes on more often and the needle on the temp gauge is slightly higher than usual! Can't decide on whether to drain the system or not. I would appreciate any advice on this from you please.
Thanks,
Mike.

I'm no expert but I think that it may have an oilly content? So less able to transmit heat perhaps?

The Factsheet from Kseal says "The copper in the K-Seal® formulation not only contributes to the strength of the repair but it also helps to conduct heat across the crack or hole. This eliminates hot spots that would normally form with a non-metallic repair. Copper is also very friendly to copper, bronze and aluminium radiator cores, which makes it safe to use with all types of radiators."
So it could be the copper in the formula that is conducting heat better so raising your temperature, I'm no chemist but copper does conduct heat very well........
I know some folks here have Kseal in their Bongo's for prevention rather than cure, maybe one of those has a Mason and could give you some feed back............p.m Nevets.....he may be able to help

It's also possible that the K-seal is blocking up more than just holes, but is also reducing coolant flow in your radiator. The Mason gauge would pick this up as an increase in running temperature.

Hi Mike,

I'd personally be tempted to drain, flush and refil the system if it's running hotter. I'm no expert on this but I always thought additives such as this were not really a good idea, ok they may fix a leak to get you home in an emergency, but with things like radweld etc I've been told by people that know better than me not to use it.

to agree with that....I would't add anything to anything except in the most dire emergency........I would guess it has coated the inside of the Rad ,,decreasing coolant flow

Hi,
Some worrying feedback there ! Like mikexgough says, If anyone else has got kseal in their system as a preventetive measure, I would like to here what your thoughts are. Without the mason alarm I would not have noticed but I have had to increase the alarm ever so slightly. (about half a notch). Still not sure what to do now!
Thanks for all your feedback,
Mike.

Hi Mike,
If this product is raising the temp in a once normal cooling system I would remove it, flush and bleed the system.

The only one I've been recommended to use is "Bars Seal" the dry one that is like a stick of Oxo (or a dried dog t**d) in a plastic tube.

I've been told, but can't confirm either way, that it doesn't have the unwelcome side effects of the liquid ones and really does work.

I have used it in other cars with temp gauges that work properly and never seen any untoward overheating effects and it really has sealed the leaks.

I once used Bars Seal in a potentially bad situation: leaky water pump on my Chevrolet Astro van, needed but couldn't get hold of pink coolant where I was (Belize), and would have had to go across the border to Mexico to get coolant or repair. The Bars seal stopped the leak completely within a few hours, and I got all the way back to the US (months later) without ever topping up with coolant. My life is not that exciting anymore.

The Astro did not have a damped temp gauge, and the Bars Seal made no difference to the indicated temperature. Maybe it would be a better choice for the Bongo than liquid sealants like K-seal? Bars Seal won't help if the bongo bursts a pipe, but could be a good thing to carry around to temporarily deal with smaller leaks (and no, I don't work for the Bars Seal Corporation).

If you google Kseal there are many who swear by the stuff..........one on a Vauxhall forum claims to have put the stuff in started the car went for a run then was stuck in traffic..temp gauge went up as it does in traffic but no overheating...

Maybe it is okay to have in and maybe it raises the temp slightly.....you need to weigh up the pro's and cons.....it will probably save your head if a hose goes........but are you happy with it as it sets your mason off....if you are happy with the Kseal in your motor then adjust your Mason.........the AA use this stuff too....

I used Rad Weld in my 306 since it had a leaking heater matrix. 9 hours replacement job or £6 for Rad Weld. It stopped the leak and I had about 26k miles out of it before changing the coolant, no overheating side effects or any signs of it running hotter. Once I changed the coolant I put a bottle straight back in, the matrix leaked a tiny amount before sealing again. I had another 15k out of it before I sold the car and the new owner hasn't had any problems with it.

I used it in an emergency, it was basically supposed to last until I had time to change the heater matrix but since it showed no ill effects I carried on with it. A permanent solution will always be better though.

Ok, I think I will drain the system and renew the coolant, minus the kseal! Shame really but I thought I was doing the right thing at the time. I am going to change the thermostat at the same time just in case its playing up. We are off to Dorset next week and dont fancy risking it! I will update as soon as I have carried out the work. Thanks to you all for sound advice.
Cheers,
Mike.
