93 loyale exploding coolent?

Featured Replies

Was driving a Little while ago and noticed my car getting hotter than it should so I pulled over and saw lots of coolent smoke coming from my hood. I popped the hood and coolent was covering pretty much everything behind the intake manifold. Couldn't see any bad hoses but I don't really know the cooling system in this car. Any ideas? I need it fixed asap. Thanks!

Could be one of the heater hoses or that little line that snakes under the intake manifold but I would first check the heater hoses.

Heat hoses, the small coolant lines on the intake to the block, or intake gaskets.

That's what I was thinking but I really need a radiator pressure tester so hat any coolent leaks will show.

They won't nesisarily show. Been there, done that. It is very likely you will need headgaskets. Overheat due to low coolant kills headgaskets.

It wasn't low on coolent and was like a hose sprayed it out. It didn't overheat like a car does with blown headgaskets it was just a little warner than usual maybe a little more than a third of the way up the temp guage. Plus the way it sprayed everywhere isn't like a head gasket would.

I wasn't saying the head gasket blew, causing the spray.

 

I've seen a slow leak sneak up, and not be noticed until the low coolant caused a mild overheat.  In all cases I have experienced, the head gaskets then sooner or later failed, usually, the milder the overheat, the slower the failure.

 

I've had a hose fail, spraying coolant, and noticed when the car began to run hotter than normal.  A number of months later, the head gaskets began to fail, bubbles in the coolant style.  Very small and slow at first, gradually worsening until unusable.

hose engine off with water (properly/carefully protect ignitino/electrical stuff).  so the water evaporates and leaves you a dry engine to look at.

refill with coolant

start engine and watch it idle with the hood open until you find the leak

rev engine with throttle body if needed

Clean and dry the engine off. Go to a parts store and purchase a UV light kit and a bottle of fluorescent dye for coolant. Run the dye through the system and check all around with the UV light. Works pretty good I just did this to mine and found the leak at the T stat housing.
