Here's the scoop: I have an 84 = Westy that I'm restoring. The metal coolant pipes are bad of course, and I = have an 86 parts vehicle with good plastic pipes. In that the diameter is = larger, some other things will obviously have to be swapped. My question = is this for those of you who have done this: Would it be advantageous for = me to swap out the whole cooling system including thermostat housing, = waterpump hookups. This would get rid of the hoses in the engine = compartment, and the ridiculous thermostat scenario on the 1.9. Will it create = problems with sensor hookups? Will I need to swap out the coolant tanks as well? I'd prefer experienced responses not educated = guessers. Thanks all.
