Thread: When coolant goes bad....

the problem isnt the coolant that flows through it, but the nasty **** that seeps in between the hose and the outside surface, the hose clamp does stop coolant escaping, but the nasties in the coolant still get between the hose and the alloy, where they sit and do the damage

on the inside, the coolant doesnt stay still long enough to cause any dramas

think of it as what happens with 2 sheets of steel laying on top of each other, wet them, the water on the top evaporates off quickly, but the water thats worked its way in between the 2 sheets doesnt evaporate so quickly and causes the steel to corrode faster than it would normally

This is a common problem on alloy parts. As sprint said it's from the coolant sitting between the hose and the alloy. You need to get some permatex aviation gasket number 3. You can get it from Bursons or auto 1 etc. Put it on the alloy part and then put the hose on. It stops the corrosion and helps seal it.

Search is your friend,heaps on this site on this subject.

I always use demineralised water,get it from the supermarket or Supercheap,autobarn,etc.Its cheap.

Some of the LR specialists use top quality green coolant,see JC posts on this site & also Rick130,i think.

MR auto in Brisbane use Valvoline ,i think it's called G5,& its green.

Others swear by the red suff,LR use it in the TD5's from new.

Good luck
