Will antifreeze damage a timing belt?
Yes. Antifreeze will cause damage the rubber compound in the belts. If you do not replace it now then it will slip and may cause the water pump installer to not warranty the work.
Is it safe to drive with leaking antifreeze?
If your radiator is leaking, coolant will be lost and the engine will have the potential to overheat. You should not be driving the vehicle anywhere, and should have a mobile mechanic, such as one from YourMechanic, inspect and potentially replace your radiator, as the car will be prone to overheating.
Can you seal a coolant leak?
If a radiator hose has a small leak, something like Flex Seal can be used to patch it for long enough to purchase a new hose and do the job right. If your radiator evacuates its fluids and the surrounding air is below 30 degrees Fahrenheit, you can drive for a short distance without damaging the engine.
Can you change the timing cover on a Toyota 4Runner?
Toyota claims a 10K OCI is good for the 4Runner. I say NO – will change every 5K with the 0W-20. Both the 4Runner and Tacoma have 1GR-FE V6 engine, although they are not really the same engine. Water pump/timing cover more accessible on either. Told the wife when the Avalon gives up the ghost we are buying a 4 banger Corolla or Camry.
