Have a leak at the conection to the radiator. I'm thinking it is the O ring. dealer shows O ring includde with the hose and does not list size for the O ring. Any one have an idea what size ? Like to figure it out before pulling it off.

Thanks

Sure it is not the waterpump? Check the pump weep hole by the balancer for signs of leaks.

No it's right at the conecton to the radiator. Has to be the o ring or a crack in the plastic

mine did the same thing. Had to replace the whole hose. Dealer was a rip, I ordered from a online parts dealer. Mine was a small leak in the factory glue joint on connector to radiator

I noticed that mine is seeping at that connection too. What a dumb design! Long term I think I'll look into getting a custom radiator made that uses traditional hose clamps to attach the hose. For now, guess it's time for a new lower hose...thanks for the tip!

I took mine in. They said it needs a new water pump. $1200 they said its 8 hour job. Seems like a rip off?

It's not an easy job and i bet the water pump retails for over 300 bucks.

GM Parts Direct shows it for $159.00.

So that means they are charging 130 an hour. What bunch of bullshit. I wish we could charge that.

You could charge that.

Not as an electrical contracor. If we bid any work at that we would get Zero work. Anyway I called them up today and they claim its a $450 water pump. I think its time to find a new mechanic
