2.4 v6 coolant loss problem

[daplaya]

Hi guys... Have searched for this but can't find any threads with same symptoms as mine..

Every 3 days or so I'm having to top up my coolant. Temperature is sitting just above 90. Car is not overheating.
Also for a couple days now I'm not getting any hot air from my heaters.
Can't see any visible signs of coolant coming out of the engine, and no water in my oil.

Any help would be great...cheers

Two places- internal leak or external.

Internal: If it's a slow leak, it can boil off from your oil fast enough that the oil looks OK. No mayo look at all on the oil fill? The only way to be totally sure is to send a sample out to a lab like blackstone. Out the exhaust... Again slow leaks can be hard. You can pull the plugs and look for signs of a coolant leak.
External: Look under the carpets to make sure its not pooling up in the large recesses. If you pressurize the system for a few hours, you should get a large enough volume to create a puddle. Since the car isn't moving and cold, it will make it easier to spot. You may want to google coolant leaks on your motor. From what I read, leaks onto the plenum are common and they tend to dry up since the engine is hot.

Thanks. No mayo on oil cap at all. And no heat coming from heater blower at all.. Its a weird one.. Will check for puddles under carpet in recesses.
