1998 cadillac catera anti-freeze leak

Periodically, after car heats up about a pint of anti-freeze leaks out somewher4e near the bottom of the reservoir. The weird thing is this only happens about once a month. No lights come on and as long as I refill the reservoir the car runs fine. Why would this only happen once in a while, I'm stumped. Also my car uses dexcool antifreeze I don't know if that makes a difference. The heater doesn't work either. Would that have anything to do with it?

First things first don't use Dexcool.

It would happen only once in a while likely because the overflow bottle doesn't always fill to the point of where the leak is located. It would be very easy to unbolt the bottle and fill it with water to find the leak and patch it up.

Yes, most of the vacuum hoses are emission related,having a leak will cause what ever the hose goes to get more air than it needs, replace the hose. If the light doesn't go out, have a code scanner hooked up to the car to put it out. If there is an autozone auto parts store near you, go there, they will do it.

Coolant leak


You should be able to, so yes. If you have a coolant leak the pressure will build and slowly decrease or it will not get to the correct pressure. Unless the leak is in the radiator cap itself as the pressure tester generally uses a different cap.

Car leaking coolant


First of all ensure that your car is leaking coolant fluid, and what is dripping is not just water condensation from the air conditioner.
If you have a coolant liquid leak, it can be from one of the ducts leading to radiator , from water pump or radiator itself. Check liquid levels, and if you have a leak have the car inspected by a qualified mechanic.
A broken water pump, for example, can cause your motor to blow in few miles.
