I have a 2004 4Runner 4.0 V6. The previous owner put DexCool in it. I would like to put Toyota Super Long Life back in, but I need to get all the DexCool out.
I'm planning on draining, attaching a flush T to the heater line, blasting tap water through the engine for about an hour to really push all the Dex out, then flushing the system with distilled water to remove the tap water minerals, then drain and refill.
The problem is, I will almost certainly have water remaining in the engine and adding the pre-mix TSLL will result in diluting the mix to less than 50/50. It gets very cold in my area, so I need proper freeze protection. TSLL is not sold as a concentrate, or this would be easy.
Should I just go with a TSLL equivalent (like this: ) in concentrate and add 50% of the cooling system capacity, then top up with distilled water? TSLL is by all accounts great stuff and about the same price as any other option at my local dealer, so I'd really like to use it if I could. Thoughts?
Potential concentrate equivalents are:
