Ok heres the thing I have a 99 camaro and it seems to be leaking antifreeze on the passenger side of the car. I noticed this when I put the A/C on for alittle while and then turned it off andwent inside, and come back to my car there is a puddle of antifreeze on the passenger side on the floor board. Does anybody know what this is Possibly a bad heater core? How difficult is it to change it out? Also I am going to be changing the spark plugs in the car so what would be the best way to change them thanks

 

If the cabin smells like antifreeze and has damp carpet, you're most likely facing a defective heater core. It requires disassembly of the dash, and the exact procedures can be found in any decent Camaro repair manual. As for changing the plugs, underneath is easiest in most cases. I had the best luck putting my car on a lift, and letting it cool for a few hours.

 

Ok so I would have to remove the whole dash in thecar thanks, Also I dont have a lift so putting it on jack stands in the front and removing the tires would that help changing the plugs??

 

Are you sure it's antifreeze and not just condensate from the evaporator? I'd suspect a plugged drainline, especially if the puddle appears only when the AC is used.

I can change the plugs in less then 40 min, all 6, from the top. I use a Snap-On plug socket with a universal joint and a regular socket with a 1 inch extension to start the plugs in the head by hand.

FYI: ALWAYS replace the plugs on a stone cold engine and use anti-seize on the threads.

 

Indeed. Check the draintube before it develops into a damaged evaporator!

 

ok found the problem I need a mass air flow sensor if anybody on here has one im intereseted in it mine is bad

 

I'm confused, how does a MAF cause leaks inside the car?

 

ok everything is done heater core replaced new maf and new belt installed runs great now
