Hey, I've been out of the community for over a year I think, just having to deal with life, hospital visits for family, securing work etc. ... so please don't give me the rtfm/google search animated dealie.

I'm wanting to clear out some of my coolant and prime it with wetter and/or this heater hotter. I as of a few months ago now use one of those globed oil extraction pumps. After thoroughly sterilizing the tubing, is it really useful for extracting brake fluid, anti-freeze mix, tranny fluid and gear fluid?

I'm now primarily using my 8 as a daily driver, though I do take advantage of any canyon or even just a nice set of curves when the opportunity presents itself. I'm in So-Cal. I've not used wetter before, but I picked up Purple Ice and also DEi Heater Hotter which claims to warm-up 50% faster (though I'd get much less since I'm sticking with 50/50 blend). What drew me to that is that I'm currently running 15w40 Rotella T diesel, so the claims of HH sound good to balance the slow ramping of getting the oil up to operating temp.

So, PepBoys was out of both Castrol 10-40 which I normally default to, but my PB never carries that so I've been using the Rotella 15w40. They were also out of that. So, I don't have a SOHN adaptor, but I've read that the Mobil1 Euro 0w40 fully synthetic is safe in a 13-B. So I'll be first swapping that in.

Switching to 0w40 will probably not require the Heater Hotter .. I was primarily concerned with that to heat up my thick diesel oil quickly. With Mobile 0w40, should I still run the Heater Hotter, or instead use the Purple Ice, or should I use half dose of each?

One last question, when I've jacked up to swap gear and tranny oil, I know to just refill until it leaks out the drainage plug. When using an extractor, how do you judge how much to remove, and how much to fill without overfilling since the drainage plug isn't removed?

2. The water wetter/heater hotter/whatever BS is snake oil.

3. Search, all of the answers you seek are here already.

I'll have to search on Facebook but I recently saw a pic of a teardown of a 13b that used water wetter ... coolant passages were disgusting. literally caked onto the inboard edge of the coolant passage.

Water Wetter is designed for use with straight water. In that environment( 0% coolant) it does add back some of the rust-inhibitors that coolant would have given you, and it does have lubricants for the water pump and coolant seals.

Water Wetter in coolant is a bad idea, and generates a coolant sludge that can be fatal to any engine.

Distilled water and coolant that's it. Buy a upgraded pump hoses and lower the fan temps. If you wanna go crazy upgrade to a better fan pack. 9k has a post somewhere read up

Also check mazmart thermostat. End this thread

Cool, thanks much for the info everyone. I'm returning the heater hotter and wetter. I knew that wetter was primarily useful for use with distilled water in areas that don't get cold, but I was completely unaware that it coagulates when mixed with antifreeze.

It coagulates regardless, please reread post #2 with conviction & belief
