Coolant Leak - Updated

Maybe that pump up front with the hvac system

Really need to pressure check it with a pump to see whats happening. hard to guess without seeing it

 

I as going to say the same thing. I believe there is a pump (common on many cars) that recirculates the coolant up to the heater core in the dash. That pump is located in the front trunk. So it is pressurizing the system with coolant when the ignition is turned on (and the HVAC system is on). I would suspect there is a leak in one of the hoses or the heater core...time to remove the trunk liner and investigate where the coolant is coming from.

If you need that pump, I have a brand new one! Purchased a new one only to find out HVAC multi pin connector was the problem... PM me if needed...

 

If you pull off the undertray there is a connection roughly under passenger seat I think. Mine leaked there a little. It travels underneath on the undertray till it hits a gap.

 

Great news, should be a connection then, not the waterpump itself. Could still be the connection to the waterpump however (with pressure from the heater helper pump). The large diameter rubber hose that goes to the aluminium pipes that run across from side to side. If the hoses there are not moist, then it is most likely underneath the car.
As said above, remove the undertray and you will be able to locate it easily.

 

If it is your front pump it looks like this.
Replaced mine, the hardest part of this fix it getting that fricken carpet out and back in.
If this pump fails fluid gets everywhere below it, so tracking it down can be a chore.
It will soak the carpet, that's a guarantee.

Dang don't remember mine costing that much ?
Got mine from Ricambi, but I also have a bad habit of not focusing on the price when buying F car parts
It usually takes 4 digits in the price to attract my attention.

 

The replacement @ $322 didn't alert me... guess I'm "used to" Ferrari pricing as well.

 

These may work....

I always call Daniel and just order the part, later I always find it somewhere else ......
Usually the exact same part at a much cheaper price
I think when I called the Ferrari dealer they were talking $700 range or close so anything less was a steal.

electrical connections could be different, but easily adapted.

 

Mine used to go away when engine was warmed up and leak if car got too cold like in winter.

 

David, do you have an update on this?
