Got a problem I’m hoping someone may be able to help with. I’m losing around 2 or 3 litres of coolant per day (of driving). The truck’s never overheated and I’ve been unable to locate an obvious leak. On a couple of occasions I’ve spotted a tiny pool of water under the truck in a position that corresponds with the reservoir overflow. This issue seemed to start around the time I had the calorifier heating coil fitted. This is fed by long flow/return rubber hoses that run from the front to the rear of the vehicle. Initially I suspected a defective radiator cap, on inspection this appears to be fine. I’m now wondering about the coil feed hoses expanding under pressure, drawing water from the reservoir, then shooting it out through the overflow pipe when it cools. Does anyone else have a similar set-up or problem or any idea what may be going on?
