I found two leaking when I replaced my coolant tank.

Next morning, I notice the water is below the min line, so I add a bit more (now having used a total of about 1/2 - 3/4 gallon).

I need some help checking a potential problem with my 2000 C4 Cab.

I'd hate to loosen and reconnect a hose that already is properly connected.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I need some help checking a potential problem with my 2000 C4 Cab. Last weekend I noticed the coolant level was below the min line. I haven't had any problems with high temps, but decided to add a few cups of dionized water to get it mid-way between the min and max lines. Unfortunately, I did not screw the cap on tight enough and left a puddle of coolant behind my left wheel after a 20 minute drive. I topped up to just below the max line with dionized water. Next morning, I notice the water is below the min line, so I add a bit more (now having used a total of about 1/2 - 3/4 gallon). I haven't driven the car again, but the water is again just below the min line. I don't see any signs of coolant leaking. I'm not sure if I have the updated coolant expansion tank, but the cap number ends in 01, so I think the cap is the "newer" one. I noticed that one of the coolant lines doesn't seem to be seated fully on the white connector indicated with the arrow on the attached picture. It doesn't appear that anything is or has been leaking from this connection. I don't know if there is supposed to be this gap, so I'd appreciate if someone could take a look at their car to see if your coolant hose is connected in the same way. I'd hate to loosen and reconnect a hose that already is properly connected.
Thanks for your help.
Check your spring clamps. I found two leaking when I replaced my coolant tank. There is a TSB out for replacing the spring clamps with the screw type clamps per my mechanic. I didn't know about the TSB, so I just put on generic clamps.
Good tip on the spring clamps, StephenB. I'll be sure to check them.
Loren from Renntech confirmed that the white bit in the picture is normal. I'll look for possible leaks and keep an eye on the levels.
Not sure that I need the third radiator, but I'll look into it. High temps really haven't seemed to be an issue.
Thanks all for your input.
I rely on the electronic oil level gauge mostly, but one reason I love having a real dipstick ('02 C4S in my case) is so I can actually look at the oil.
Had a 944 once that blew an oil cooler seal, coolant mixed in with the oil, not a good thing.
This is a source reference. Confirm exact model applicability in the original material.
