shoot, I have been changing my oil every 10 k for more than 20 years using store label synthetics. So much for top shelf.Meh. Most top shelf mass produced oils are good for 10k+ (per said oil manufacturers and IOLM's), but somewhere around 94.24% of this forum says to never take them to 10k.
My owners manual says change coolant at 100k (miles) then every 50k. I wouldn't run blinker fluid for 15 years, let alone coolant.
A nice citric acid flush should clean that right up! Of course, all my Dodge/Ram trucks rusted onto the OUTSIDE too, so at least the engine would match...My dodge has heavy rust on the coolant passages looking at it from the thermostat housing. Not sure if that's from not changing the coolant or a large quantity of water being used compared to coolant
New coolant, especially the Asian phosphate OAT coolants, just don't seem to go bad. I've done partial changes on the Toyota SLLC pink using cars in my sig, but even after 17-18 years, they still look like new inside.I have never changed my coolant, and have never had it changed, or topped up unless I was changing the thermostat or radiator.
And that is for the last 20 years. Never had an issue. Only time I have changed the waterpump is timing belt services. Never leaked.
Same with brake fluid, which according to my shop comes back at sub 1% moisture (aka 0 on the reader because it can't read lower) and perfect health.
Unless you are on the track, towing, beating on your jeep, or what ever, highway driving is not gonna wear things out as quickly as the "recommended" from shady mechanics who will gladly change everything on your car ever month.
Or maybe its because I only buy Honda/Toyota.
Won't fix the pitting, will probably cause the heater core to start leaking tooA nice citric acid flush should clean that right up! Of course, all my Dodge/Ram trucks rusted onto the OUTSIDE too, so at least the engine would match...
Yeah the thing is a coolant change won't keep the seal on the waterpump from hardening and leaking. That's what happened on my other dodge diesel that has a maintained cooling system. Basically a flat gasket like on an oil filter that turns hard as a rock. The bearing was still fine. I assume every pump has a different sealing setup, because I don't see how not changing the coolant would cause wear to the seal on that concentric brand water pump.
Preventing oxidation/corrosion and freezing, off the top of my head. Otherwise, straight water would do. I'm assuming the post you referred to was talking about coolant (the mix of chemicals known collectively as antifreeze) though he might have just meant "coolant - any liquid you can run in a cooling system"Like what?
Agree. My son's KIA Rio in signature got a drain and fill at around 120K. I'll do another drain/fill next oil change. We live in the Carolinas, so not exactly freezing here. Coolant still tested to below zero, but I did the drain/fill anyway. Coolant came out looking very clean.New coolant, especially the Asian phosphate OAT coolants, just don't seem to go bad. I've done partial changes on the Toyota SLLC pink using cars in my sig, but even after 17-18 years, they still look like new inside.
