Its possible you are using the wrong size o rings, but you should check to see if the pipe at the connector end is not cracked or has a porose hole etc also check that the connector on the oil cooler is not cracked too

Why us my 2007 pontiac torrent losing coolant?


When the oil was changed, did anyone reset the oil life monitor? It needs to be reset every time an oil change is done. That would explain why it is telling you to change the oil so soon.If you have a bad head gasket, antifreeze mixes with your oil. Check the oil on the dipstick. Does it look normal? Check under the cap where you pour the oil into the engine. Is the oil cap wet on the bottom? If yes, and the oil on the dipstick does not look normal, the head gasket is defective. It most likely would leak where the thermostat is located, since the gasket seal was taken out and replaced with a new one. It may not have been done correctly. There may be a puncture in a hose. There could be a crack in the coolant reservoir tank. The thermostat must be stuck in the open position or the thermostat was installed backwards for it to take that long to heat up. Refill the coolant reservoir tank with antifreeze and water before driving the car to avoid severe engine damage.

2006 Pacifica 3.5L I have a small coolant leak on the passenger side. The coolant will trickle down and drip from oil pan. The puddle is only 2 inches wide. I did a pressure test at 17PSI and I lost 2PSI...


It is a possibility that the leak may come from bad seals from the water pump or a bad water pump. If you also observe bubble in the coolant inside the radiator when the car is running or water coming out of the exhaust you may have a bad head gasket. The coolant comes out of the bad part of the head gasket near the outside which lets water outside the engine as well.

Im trying to stop a internal leak on in the cooling system do i pour directly into overflow tank then> Pontiac grand am 99


If you are putting in stop leak then yeah it goes in there because the radiator cap is on the overflow tank. But I wouldn't recommend using stop leak. The engine likely needs new intake manifold gaskets because that is a common problem with that engine. It would be better to just replace the gaskets

there is a valve in the hot line to the heater core, it may not be opening. or you might have to disconnect the heater hoses and flush the heater core, stop leak will some times stop up core since tubes are very small

Im having a problem with my 2003 Chevy Malibu leaking coolant. What do I do? What do I check? I have no idea where its coming from. I can drive and when I park the car it starts to pour out coolant. I took...


actually it is not good idea to replace your coolant by water only you shoul full your coolant system 50/50 mixture coolant and water because coolant has uniqe smell and color so easier to identified leaks.
first check your oil condition and coolant reservior for any coolont oil mixture for figure out head gaskets condition if you have any oil coolant mixture in oil or coolant you have a blown head gaskets this will send you to mechanic if everthing looks clear then go front driver side bottom of radiator and open the drain **** (make sure car is cool and put container under because coolant is toxic and mess up your drive way )open reservior tab too and drain all the water close back drain **** probably your vehicle prefer dexcool(red color)
fill 3 qt dexcool then water or just buy ready mix run the engine with reservior tab open and check coolont level add more if necesery suquize collont hoses for air inside when engine start hit up close reservior tab. on passanger side front of the engine has a coolant drain plug open with number 8 wrench untill you see the coolant come out( bleed the system for air) make this several times turn on your heat too and bleed again and watch your upper and lover hoses for any visible leaks fallow small coolant lines like under throttle body check thermostat housing under throttle body on 3.4l engines check under radiator if your pressure cab dosen't look good get a new pressure cab .shut of the car and check for leaks once you find out where is leak from easy to fix it.

Toyot Rav4 1996 Uses Oil


It has to be either burning it or you have a leak. If you changed the oil and overfilled it a gasket may have blown. try pouring a can of engine stop leak. Maybe it will help.

Thick blue smoke. no oil leaks new spark plugs and spark plug wires. checked all cylenders cant figure out why its smoking.


Hi! Chris, There are many causes of oil burning or exhaust smoke. There are three different causes of normal oil burning, 1; worn valve guides (smoking during deceleration), 2; worn cylinders and piston rings (smoking during acceleration), 3; split or worn out valve seal, or damaged intake manifold gasket (smoking all the time). Of course there are several variables in this equation. Sometimes coolant can also get into a cylinder and cause a blueish smoke. If you remove the spark plugs and use a pressure pump on the coolant system (radiator), coolant should leak into the intake manifold or cylinder. Coolant leaking into the intake manifold will leak into several cylinder through the valves. So, what year and how many miles are on the Jaguar?
