Coolant leaks

I used to have a 4.2 Range Rover that cracked a liner after the water pump failed and it overheated. I brought a new engine, but as a temporary measure I brought one of these. Cargo Seal Up

It cost about £10 and I thought it might slow down the water loss until I got time to change the engine. I kept the Range Rover for 3 years after that and never changed the engine and never needed to top it up with water either. Very impressed for £10

My fathers 3.9 Range Rover had a weep from one of the core plugs recently, that would have required the engine out to replace. I tried the new version that can be mixed with antifreeze K-seal
with the same result.

Great products.

Craig.

I received on Monday morning (in Paris) the product I ordered in U.K. If it works as efficiently as their shipping I can hope great results.

After weeks of doubts, and unable to get a modern new intake manifold that could be put in place quickly, I decided (reluctantly) to put the K-seal in the coolant.
Miracle: it worked and after 600 miles I had the pleasure to see that my coolant level is perfectly steady. Thanks for the advice.
But I do not like this procedure that I consider as temporary. And it is not satisfactory because I do not really know what I have done putting this product in the water passages.
One remark: the water temperature seems now rises a bit quicker and seems higher by 10°C.
It was the only way to get my car operational for some races this summer but I really wait for the real solutions: a proper new intake manifold for my actual engine ...and as a spare, a new engine.
Besides that, my actual "old engine" works perfectly and has all its power.

Hi Queenie; thats as it should be, temp will go up now that you ave a sealed system as the water will be under pressure and will go to a higher temp before boiling; poreviously it was just leaking out of the system at 100C boiling point (or less), now it has nowhere to go you have a true temp reading, and proper cooling. As it should be. The additive will do nothing to your water passages, it only solidifies when it escapes to atmosphere (through a crack/pin hole leak etc); other wise it stays in dissolved suspension in the water and just flows around the cooling system freely.

Worry not.

Thanks for these clever remarks.
