coolant draining very fast

hi guys...i dont know whether this a technical problem, but thought i would post it here...i have just had a new water pump fitted to my jeep compass, and over less than 24 hours, i have had to put 5 litres of coolant in the reservoir, it just keeps taking it...may it be that the mechanics did not replenish the coolant when finishing the job?,( which i would assume they would have to do)...i could not check the rad' level because i cant find the rad' cap.


cheers team

What is the model of the car? On the second gen, rad cap is on the overflow bottle. So there isn't one on the radiator. Anyway, I highly doubt they would forget to add coolant. But they might have gotten lazy and not completely bleed the air out out. If the drop in coolant level eventually stops, it is probably the case.

In either case, check the hose fittings and etc. for leaks and/or residue build up. Although at a rate of 5 liters in 24h, you would see a poodle under the car. Just to be safe, also check the engine oil for coolant and check the exhaust for white smoke. I highly doubt changing water pump can cause the coolant to leak inside wngine block, but if it is not going anywhere else, it can be there for some weird reason.

no, i only had to put the 5l in, it recently seems to have settled down..it has stayed about an inch 1/2 from the bottom for couple days now...the temp' gauge reads normal...all this from having a new water pump fitted.

i am taking it down to the garage today and giving them 4 days to identify the issue and fix it, i have hired a car for 4 days....the big question is....where has all that coolant gone?

They probably didn't bleed the air out of the radiator after replacing the pump and you basically did that.

Did they turn on the heater? Otherwise air might have gotten trapped inside the heater core, although I am not sure if it would take that much of coolant. If the coolant is not leaking inside our outside and if it is not being burned, the only explantion is that they didn't fill it up completely

It can. But you said there was no coolant inside the engine oil, so that why I assumed it wasnt the case.

Your engine oil will turn "chocolate/caramel colored" if there is coolant in it. Also, there will generally be "milky" residue under the oil fill cap when you remove it.
