Thread: Small Coolant Leak??

So i've been fixing my 200sx SE-R for a few months now, everything is going well except there is a small amount of coolant dripping out. I swapped out the water pump just incase and that wasn't the issue, I replaced the coolant hoses and that wasnt it either. It sees to be coming from the which seems to be the most frustrating part of the car to get to, behind the water pump under the intake manifold. I see the coolant dripping but I can't pinpoint an exact reason why. Any ideas??

Btw I also just found this part in my garage, I looked up the part number and it said PUMP ASSY, but i'm not sure which pump its to so I don't know whether or not it could be contributing to my problem...here are some pics:







The numbers on it are: t671710080, then 49110-4B500 if you can't read them in the pic

Any help would be much appreciated, this little leak has been driving me nuts!

Thank You

Sorry can't help right now with the leak question.

That bracket is for the power steering pump. Let me find a picture...

Edit: Here you can see it with the sticker on.

No worries man, but thanks thats a huge help regarding this mysterious part i had!

Are you having any overheating issues? How does the oil on your dipstick look?

It took me a long time changing parts in my sr20det for me to figure that out. That leak is coming from the back of the head, a coolant hose that connects to your waterpump i think. There is a rubber piece in the middle of the metal conductors for coolant, the last rubber piece (hose) deeper down is the one that usually fails. It took me about 3 months of constant work to figure that out in my car, ended up replacing all the coolant hoses on it, water pump gasket and intake manifold.

You should really change both hoses in red however, the one leaking is probably the one to the right, the lowest one.



BTW... i work in windsor if u need me to stop by after im out of work just lmk

Awesome man thanks! this is a huge help! It's been driving me insane for months! But yeah that'd be awesome, pm me your number and i'll definitely shoot you a text sometime!

There is a coolant plug back there behind those pipes that I've found to leak.

FWIW, G-spec sells those hoses. Might be easier and cheaper than a dealer.

Thanks, i swapped out the hoses, they seemed really beat up and had huge slits along the rims, i was sure it was the issue, but it's still leaking for some reason.



Thanks! this is my next step, gotta figure this thing out

Try this: Turn the car on, let it leak for a little bit, then take everything apart and try finding the leak source this way, hopefully it's not the coolant line itself that is leaking...
