tmw188 Posted June 28, 2021 Share Posted June 28, 2021 D@mn service place was wanting to put in the OAT Coolant says that’s what they have put in hundreds of vehicles. I told them about the sensor problems that are encountered with using that on the older motors. Then he texts me a pic of ES Compleat and I said I didn’t want that either and that I wanted the Fully Formulated coolant and that I would bring it to them. Hell even if they need to make a little on my coolant that’s what I want to use. Waiting to hear back. If they won’t give me what I’m asking for I’ll go somewhere else.

tmw188 Posted June 28, 2021 Share Posted June 28, 2021 Did we ever find out how many gal it took for your motor? Link to comment Share on other sites More sharing options...
millionroy Posted June 28, 2021 Author Share Posted June 28, 2021 Unfortunately no. I have learned a lot more, but have decided to have my RV guy do it. He owns a 2001 Holiday Rambler like ours, and he couldn't tell me! Sounds like it will take several flushes and nearly impossible to drain the engine block. Plan on a final flush with deionized water, filling it with Peak Final Charge 50/50 and maybe then I will know. Will check with refractometer afterward to be sure we're protected down to 0 F which will be fine for this area (Western NC, elevation about 2300 feet.) Thanks for asking.

tmw188 Posted June 28, 2021 Share Posted June 28, 2021 (edited) Ok thanks Roy. Posted that question twice by mistake. Thought I put it in another thread. Running around and forgot I had asked earlier. Getting forgetful I guess. Edited June 28, 2021 by tmw188 Link to comment Share on other sites More sharing options...
