Is it normal to lose a small amount of coolant?
Q: Is it normal for the coolant level to drop? Yes, due to the extreme engine temperature, the water element within the Coolant tends to evaporate, resulting in a coolant level drop.
What causes coolant failure?
Corrosion within the radiator is one of the leading reasons that coolant leaks. As the tubes get older and weaker, you may get sediment or debris inside that causes a leak. The sealing gasket between the tank and the radiator can also wear out, and that could lead to a leak.
What to do if your Toyota Taco has a coolant leak?
Look around the engine very well – pull off the cover plates on the bottom. Look for spots that look like a dried up leak. This might be easier if you don’t drive the truck for a couple of days and then look for coolant as well. I had the same mysterious coolant leak on my 2000 Taco.
Why is my Toyota 4Runner losing coolant?
I have a 2003 4Runner V6 with 108K miles on it and I am losing coolant. I noticed recently that my coolant resevior was empty, open the radiator cap and it was low as well. Topped off the radiator, filled the resevior, and with a week the resevoir was empty and the radiator low. Refill both, same deal.
How often does a Toyota radiator lose coolant?
Each time, over the course of a week or two the coolant is always gone from the resevior, and the radiator is down maybe 1/4 of a gallon (maybe a little less) each time I check. It is a consistent level down. There are no fluids leaking that can be seen on the pavement or anywhere under the vehicle.
Is it normal for transmission coolant to leak?
If yes, that is just more sign of HD blown.. The only other thing you can check is your transmission fluid: there is a remote chance that transmission cooler inside of the radiator is leaking and antifreeze is getting pushed into trany… This actually was known issue on 3-rd gen 4Runners..
