    I'm surprised at the ph level of the prestone concentrate... I thought it would be higher

    Liqui-Moly Engine Flush

    Haven't heard alot about the liquid moly so good to hear. Have heard lots about the seafoam (the guys who believe in it REALLY believe in it)

    Coolant PH level questions.

    So completely drained my overflow reservoir (about 1.5L) and what I could get out of the radiator without pulling the pedcock about (.5L) and poured in the prestone concentrate. Then drove (with heat on high) until got to operating temp and ensured thermostat opened. Went to MR LUBE and they...

    Coolant PH level questions.

    Thanks everyone... I'm going to drain out a couple liters of the coolant and refill with the concentrate. I suspect that my initial way of "estimating" left me with a ratio of around 55% water and 45% coolant. The recommendation on the bottle is for a minimum of 50% coolant and can go to 60%...

    Coolant PH level questions.

    Thank you so much.... the good news is its only been a couple weeks so not long enough damage anything... tomorrow I will drain out 2 liters of the coolant and replace with fresh concentrate. Then I will repeat the strip test (somewhere other than where I got the first test) and see if it makes...

    Coolant PH level questions.

    if what your saying is true then i don't understand how i could have low ph... if anything my ratio was a little light (more water than coolant) and the coolant is brand new. Does anything else cause low PH?

    Coolant PH level questions.

    so adding more coolant concentrate (increasing my ratio) won't increase my ph level (decrease my acid level) then

    Coolant PH level questions.

    I recently completely flushed my cooling system and replaced the coolant. I did a very thorough flush using a radiator flush kit, distilled water and flushing several times. I removed my thermostat, put the heater on high and drained my reservoir tank. I had completely clear water draining out...

    Prestone’s push to 10 year coolants

    I agree thats potential... but ask yourself do you think they have more reason to be biased than the manufacturer who loves to be able to sell a maintenance free car?

    Prestone’s push to 10 year coolants

    That lifetime fluid thing is just going to encourage already neglectful behavior to get worse. If you call reputable mechanic shops or transmission shops and ask them what they think about lifetime fluid.... 95% of them will tell you its a good idea to do regular maintenance.

    Owners of vehicles with ZF 8 spd transmission

    I think the drain plugs are known to be weak and strip fairly easily. Some shops have fluid "exchange" machines which don't "flush or pressure" fluid through the lines/components. Rather they undo your fill bolt and place a wand into the pan. It sucks out 1 liter of fluid then pumps one back in...
