Don't use Stainless Steel coolant pipes

[Terry Kay]

Thats on a direct contact bolt on trans.
That might cause problems.

Figure this;
The pipes are isolated from the engine with the hoses on each end--if in fact this cavitation fairy tale is a bonified problem.

BUT WAIT--There's more!!!!

RMW purveys satinless replacement coolant distribution blocks for 2wd's & Syncro's, Plus the water pipe on the left hand side of the engine!!

Better send them all back to Mike for an immediate refund for those of you that have them--these are surely going to melt your engines RIGHT NOW!!!

This pipe is a direct bolt onto the engine affair and will surely turn the interior of your engine to immediate white corroded aluminum!!!!

BUT WAIT--there's still more!!!

There is somebody out there distributing water pump to the thermostat by-pass stainless pipes & the stainless pipe that runs from the oil cooler to the water pump--

Better get them off prior to your engine turning to Jello & get a refund right away!!!!

So according the the Wizard of Oz, between the stainless coolant pipes, the replacement stainless distribution block, the L/H stainless water pump to the thermostat pipe, the stainless oil cooler to water pump pipe, & the stainless by- pass pipe to the thermostat--you all are melting the interior of your engines en-mass.

Folks have had these stainless replacement parts on their Vans for quite some time--with zero negative problems.

But yet--and the only thing mentioned here has been the coolant pipes.

Give me a break--

You guys are beyond comprehending common sense.

I think you've been spinning around in the Mad Hatter Tea Cups at Dizzeyland little too long--

I hate to keep bringing this topic up, but I find it interesting that people want to discredit facts and use opinions.

Corrosion due to dissimilar metals is a problem. There is no arguing that. With aircraft, I have to inspect and deal with it all the time. They use dissimilar metals in aircraft due to weight and strength, but are usually protected with a barrier of various products, such as alodine, zinc chromate, mastinox, and many others.

Now back to the coolant pipes. I find it funny that someone would say "hey, I had plastic pipes and my heads are corroded, so the coolant pipes are not the problem". I never did say that the pipes were the "only" problem. I'm also going to say that you may not see a corrosion difference between plastic and stainless.

The point I'm trying to make is that we are aware of a head pitting/corrosion issue. People will slap on a set of heads without properly sealing them, then they will buy a nice and shiny set of stainless coolant pipes and years later, they will say the WBX is a bad engine due to seeping / pitted heads. BUT, if you actually take the time to do things right and understand corrosion, you may avoid the problem all together.

I'm sure TK and RMW puts out a top notch product, but I feel stainless is a wrong choice. I will be using aluminum pipes with my newly built WBX.

My plastic coolant lines catastrophically failed at 80k miles, fortunately it was less than a minute of arriving home at which point most of my coolant was gone. Replaced the factory plastic coolant lines with stainless at that point...150,000 miles later I still dont have engine or coolant issues...just sayin.
