Many years ago I changed the coolant in my 1994 Mazda Lantis. I had no idea what I was doing, and the result was my water pump broke and started leaking.
The mechanic replaced it and all was good.
When I look at videos like this, https://www.youtube.com/watch?v=s--5ft5YiHg I see no reference to bleeding air from the cooling system during the initial flushes.
This guy filled the radiator up when he was doing the initial flushes, started his engine, and the coolant went down, then he topped it up. On the last fill he squeezed the pipes at the top.
This guide here,
Mentions jacking the car up, and opening the purge vents. What's a purge vent?
Overall though, what happened to my water pump? I obviously did it wrong, but it seems extreme that it would break like that.
- Will having air in the cooling system destroy your water pump?
- If not, won't air in the cooling system work its way out when you run the car for a while?
- Should I fear changing the coolant in my 2005 Mazda Bounty UTE because of my previous experience?
