Pontiac Problems? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose).
How much coolant is lost over how many miles?
Any way to get me some pictures of the area you think its coming from so I can point out the possible leak origins?
Yes I do believe some better pics would help zoomed in and out with a flashlight on the suspect area.
Do you know anyone with a cooling system pressure tester?
Hello again Chris here,
I am contacting you because the post has not been closed or rated. We have 7 days to get a post rated before it times out. When a post times out, that means its no longer on my active list (if you reply I never know it.) You have already paid the fees to get this question answered, but it appears you're not pleased, or need more help.
Let me help some more. Is there anything else you feel I could offer so you would be pleased with my help. I have the option to call you if that would be better.
Seven days from the 28th is when the post is set to close.
Man it is just to hard to tell without seeing it in person. Would you like the steps to remove the cross over to address its seals?
Yes the cross over does appear to be the most likely source. Most techs will use a cooling system pump to bring the system to max pressure so they can see the leak better.
