Have a 1995 Honda passport and is leaking coolant. Have to put it in almost every time I drive and can't go far without over heating. Coolant seems to be leaking on passenger side mostly over tire


Check the Heater hoses for a pin hole. If there is no coolant on the hoses. Check the water pump. Let the car warm up,than take a flash light look a the water pump. there is hole in the water pump that will starter leaking when the packing is bad in the pump. If you see coolant coming from the hole change out the water pump.

Coolant nissan pulsar 1989


Quite often when replacing coolant in older vehicles new leaks start to show up. The newer technology in coolant makes it a really good cleaner, and when it I changed it would clean out any bit of rust scale exposing weak areas where new leaks can form. If the leak is coming from the front of the engine where the drive belts run, there's a good chance it is coming from the water pump.

What happens when your water pump goes out?


under pump there's a weep hole, located in center of pump below the shaft that the pulley is attached, if coolant is coming out of that hole, pump is bad. otherwise, gaskets between pump / engine are leaking.

I have coolant leaking out of the fan pulley. why?


If the coolant is coming out of the one that's more to the center of the engine, it's going to be your water pump, when water pumps go bad they will leak coolant out, water pumps have a little hole in back of the pulley, that when the seal goes bad it will leak coolant through there.

How do i keep the car from overheating?


Check that the engine coolant is at the proper level. Check the condition of the radiator and associated hoses for any leaks or signs of breakage. A common cause of engine overheating is a faulty thermostat. This is a relatively cheap and inexpensive fix. Check the water pump and make sure that it is not leaking coolant. Most water pumps have a vent or "weep" hole. If any coolant in leaking from the pump it is defective. Make sure that the cooling fans operate properly when the engine gets to temperature. The fans should kick on to cool the engine. These are some things to consider. Really sorry for your trouble and I hope this helped. Best wishes.

Little plume of white smoke coming from engine when idling only. Runs great and not overheating. Really bad smell coming through vents with AC on


A little white smoke is OK from 0-15 minutes of start up.

After warm up the condensation inside the exhaust pipe AND under the hood should be purged.

How many mile is on the engine?

A well care for engine should not have to worry about leaky (pin hole leak) head gasket until 120,000 miles.

The other sources of coolant leak is the freeze plugs.

DO NOT WAIT! Take 15-20 minutes out of your schedule and see where is it leaking on the idle.

it can be at


heater hoses
water pump
freeze plugs
and head gasket


I would start monitoring the coolant consumption by making the coolant reservoir tank.

Keep tab on oil level.

====

The common A/C air vent odor are

coolant leak (even pin hole leak) on the heater core.

KEEP CHECKING the center to passenger floor carpet for wetness and smell of coolant.

and/or

mold in side the air tube vent.
there is cleaner spray you can buy to keep the mold.
