I have a 2004 SRX, v8 AWD. I've had it to the dealership so many times at this point that I've lost count. I think they've worked on finding my coolant leak four times (at least) and still can't seem to find it. Tonight I was working on a mini tune-up (spark plugs, oil change, MAF cleaning). When I removed the elbow going into the throttlebody I found my coolant leak! I must have hit the tee along the top of the radiator. When I went to replace the elbow, there was coolant running down the fan and dripping onto my driveway; had a large puddle by this time.
Anyway, I was excited I finally found the stupid leak and thought I'd share. I'll be replacing the tee tomorrow.
I've dealt with that tee breaking on these engines so much its ridiculous. I went ahead and upgraded mine to an aftermarket tee with hose clamps as it will break again. Luckily mine didn't break but just in case I used a metal tee from the hardware store. Just like the failed crappy plastic elbow design on the gm 3.8 engine which finally parts stores sell the metal replacement. 18 years too late lol. Go to the the hardware store get the tee and hose clamps from a parts store cut that old tee off and replace. Cause I think that entire hose is very expensive.
To my knowledge you are the first user to report this problem, so it will likely be a rare issue.
Not too many diy do this particular repair and just have a shop replace that entire hose.
I've done at least 6 on the CTS when I was working at a parts store right in the parking lot. Not too many on the srx I'm assuming due to the amount of space in the bay vs the CTS.
