On my 88 Turbo I daytona I notice that my temp guage tends to move around a lot. It never gets really hot but it does tend to jump up there a lot and then go back down to normal and then back up, and it will do this during normal driving. I've added a lot of coolant lately too. Does anyone else experience this with their cars? I'm hoping getting a coolant flush will take care of it.

 

I guess I'm a little tired and didn't realize how I wrote Hi! Instead of High. I figured I'd correct myself before someone other smart alec decided too.

 

Is there a puddle of antifreeze on the ground after it sits? Do you notice a funny smell or white smoke out the tailpipe? Does the oil in the engine look like oil or does it have a funny color to it? If theres no antifreeze on the ground, and the oil looks funny or you have white smoke out the tailpipe, you have a blown head gasket. The first one that went on mine dumped antifreeze into cylinders 1 & 4. Looked like a James Bond car when I started it. The one that went on my wife car dumped antifreeze into the oil. Looked like chocolate milk.

 

That's what happened when I blew my head gasket...

I replaced the head and the head gasket, no cooling problems now, in fact, I run just plain water now, and it stays cool, never goes past the first bar on the gauge...

Just watch that heat, it can crack the head easily, I learned that the hard way...

It sounds like it's just a matter of time before the head gasket blows, pressure test the cooling system, and go from there. It should hold 16lbs of pressure with no drop in pressure for 5min, if it does, you have a leak, or possibly a blown head gasket.

Just to see if it's a head gasket, perform a cranking and running compression test, if the readings are 15% difference from each cylinder, then you have a problem.

Early detection is the key... [sm=signs003.gif]
