My 06 has 425,000 on the clock, I put them all on..I’ve noticed on the garage floor a small patch of pinkish fluid.
I can’t seem to find the source, it’s seems to be coming from rear drivers side. I have added fluid from time to time,
Not much but some..so here’s my deal I’m going to have a Chevy dealer give me a quote on head gaskets replacement.

I’m thinking of buying a tester for the cooling system (psi) just to see if I’m losing any pressure, I get no smoke when starting.
Also I’ll be getting a quote on head gasket replacement from a Chevy dealer some 1-1/2 hours away.

Can someone advise me on what should be replaced as long as it’s being torn down…the only thing I have replaced is the turbo.

I’m thinking the injectors….

Thanks
