I wonder if I have a leaking waterpump! But I have a 4.2! I smell coolant on the outside of the car, and it appears I lose coolant at a slow rate. I have had the car pressure tested and the shop told me they left it hooked up to the pressure tester overnight and there was no loss of pressure?
I ordered a new expansion tank cap--I'll see if that does the trick?

I recall he showed me that the pump was slightly wet at the bottom.

I took another long drive and got stuck in rush hour traffic. Despite replacing the water pump I could still smell some antifreeze. It wasn't as bad when I got home. I'm hoping its just some residue burning off. I'm going to keep an eye on it and check the coolant level often.

After a coolant pipe replacement I experienced sporadic antifreeze smell through air vents and heated plastic smell in engine bay. Originally I thought it was caused by residual coolant just burning off but dealer diagnosed a leaking engine oil cooler and thermostat housing. Water pump not leaking but dealer recommenced to replace with the improved one.

Low coolant level and sporadic antifreeze smell through air vents and heated plastic smell in engine bay after a coolant pipe replacement, Originally I though was coolant residue caused by the replacement of the pipe just burning off but dealer diagnose a leaking engine oil cooler and thermostat housing. Water pump not leaking but dealer recommenced to replace with the improved one.

JLR will not offer goodwill so picking up the car tomorrow and will attempt the repair myself. I’m not 100% convinced the culprit is the oil cooler so I’ll add fluorescent dye and pressure & vacuum test.

Have same issue, smell coolant, had to add about 12 oz to the system, but no visible signs of a leak. Taking mine in next week. I'm told the water pump or small coolant tubes under the supercharger are likely culprits. Hope my local dealer is one of the better ones and can find the problem.
