Is it necessary to use any type of sealant on the joints between the hoses and metal parts in the cooling system?

Is it just a case of push the hoses on and tighten the jubilee clips? If sealant should be used, what sort of sealant is recommended?

Thanks for any replies.
 
Thanks for the replies.

A suggestion I have heard before is to wet the metal pipe with methylated spirits before installation. This will help the rubber hose slide on more easily, and will evaporate leaving no residue.

That's a new one on me.
I think he one to avoid is Vaseline petroleum jelly types.
The ones that are OK are silicones.

Years back you could buy little tubes of "rubber lubricant" in model shops for wind up rubber band model aeroplanes (do those still exist?) - anyway the lubricant was a "soft soap" - whatever that is.


My chum over the road jus waved a tube of this at me and said good investment: http://www.amazon.co.uk/SILICONE-LUBRICANT-ASSEMBLY-GASKETS-Quality/dp/B008HI0O6W

Wonder if the red rubber friendly brake grease would help. I had issues sealing my coolant pipes. Fortunately I bought good quality jubilee clamps which allowed me to keep tightening a little further every few days until I got a good seal as the rubber compresses.

I use washing up liquid for a lubricant (oo-er missus), but I thought the original question was about sealing? If you have trouble fitting new rubber or plastic hoses, try putting the end in a cup of hot water for a minute. But the softening effect lasts a very short time if the weather is cold!
