I understand that GE voids warranties on their blocks if you have them hot tanked. What are the cons of doing this. I am having some machine work done and want to know why I can or can't have my block hot tanked.

 

YOU MAY WANT TO CONTACT GE AND ASK THEM WHAT IS THE DEAL WITH THAT BECAUSE I KNOW THAT THE RS BLOCK CAN BE HOT TANKED ALL DAY LONG WITH NO ISSUES WHAT SO EVER. BESIDES THE MAJORITY OF HOT TANKS OPERATE AT APPROXIMATLY 175 DEGREES AND THE SOLVENT THAT IS USED IS MAINLY A DEGREASER AND AN ANTI-FOAM AGENT

 

My block is actually an RS Machines sleeved block. I just thought because GE says so that maybe it applied to other sleeved blocks as well. Thanks for the info. Anyone else care to comment.

 

i thought when GE sleeved ur block they hot tanked it for you?

They do but before they install the sleeves.

 

The confusion comes from using the words "hot tank" interchangably with "jet washer". Both use hot water and a cleaning solution. The traditional hot tank uses caustic cleaners for cast iron only. It will erode/ruin bearings, aluminum, alloys. In most places, local EPA oridinances and hazardous waste disposal regulations have eliminated this type of machine.

The modern day "hot tank" is a pressure jet washer. While they can use caustic solutions that can damage alloys most use alumiinum-safe solutions.

To be safe, contacting your sleeve installer for cleaning recommedations is the best thing to do. There are several different styles of sleeving and some require different cleaning and maintenance techniques.

 

That is great info and I really appreciate it. Thanks!

That is exactly what we were warning against. The old "Hot Tank" style cleaning system is not recommended for aluminum blocks. We use a pressure washer for all of our cleaning and recommend the same for our blocks/sleeves. There is nothing different about our blocks as compared to the rest, when it comes to the cleaning of the block. We just had a few problems with customers about 6 or 7 years ago taking the blocks to their local machine shops that weren't aware of the damage that Hot Tanking an aluminum block in their traditional solvent can do. That is why we recommended against it because unless the machine house know, which most of them do now, then it can cause damage to your block. We definitely condone washing the blocks in a jet or pressure washer, no sweat

 

Awesome. I feel much better.

 

so what does it do 2 ur block? does ur block get warped....

 

usually turns black.. ill take some pics of a block im gonna throw into an old hot tank this week (has hole in it,, just want to clean it for jigging mounts/manifolds/etc)
