Radiator cap leaking -help
Took a short drive today to run an errand and on the way home I start smelling that unmistakable coolant smell. Pull in my driveway and pop the hood and see that coolant has leaked somewhere but hard to tell from where.
I waited for it to cool down a bit and pulled the cap and the resevoir was about 2/3 empty. So, I fill it up with the special Ford yellow coolant and start it up and run it for about 10-15 min and no leaks. I went for another short drive and start smelling the coolant again and I also notice that the fan is coming on sooner and it immediately kicks up to a higher speed. My temp gauge is right in the middle where it usually is.
Get back home and shut it down and it is evident there is new moisture around the top of the radiator and down inside near the shroud and on the hoses. Again let it cool down and the resevoir is low again. This time I fill it up and start it and let it run with the cap off. Pretty soon the fan comes on and kicks to the higher speed. Then the coolant starts gradually coming up (expanding) and so I quickly put the cap on. I let it run a bit and as I am looking around coolant starts coming out the cap thru the pressure relief hole at a pretty good rate so I shut it down and fill it up and it does it again.
My first thought was that the system got too low and there is steam in the system that is burping out. However, I have had no leaks on my garage floor and no smell until today.:shrug: And the resevoir always had something in it.
Can anyone help me out?
