i replaced my radiator a couple weeks back because of a leak, it turns out the radiator was cracked. today my car is leaking coolant again from the radiator, i do not have an air deflector, do you think that is a problem? how can i protect my radiator? please help i dont want to swap radiators more times than i do oil changes. thanks

 

You don't have an air deflector? Underneath the car, the air dam? Yeah, get that anyway. It'll cause your engine to overheat, since the radiator isn't getting any cool air at all. It might be melting your radiator?

 

i did a block test at work today, and it tested positive for a blown head gasket at 27k miles but it still runs pretty good?

 

I had the same problem i kept replacing stuff and kept getting a coolant leak finally found out it was head gasket so now im getting the engine rebuilt but doing it right replacing everything in the path at the same swing so its taking longer. but when im done ill have new

waterpump
opti,
push rods
hotcam
1.6 RR's
mounts
Headers
oil pan
lifters
GM Extreme TC
1le Elbow

on top of a freshly rebuilt engine i cant wait

 

I'd look that radiator and hoses over again before I'd pull the heads. My car kept losing coolant, and I did the chemical block test, and it turned pale yellow, which is supposed to be a sign of a bad head gasket, but it wasn't. The radiator had a small crack in the plastic below the low coolant sensor. The coolant would evaporate before it would hit the ground. Finally the crack got big enough for me to see what was going on.

 

the first time i thought it was just a craked radiator, but then the waterpump gaskets blew, and then the radiator craked again. this all happend over a couple weeks so i know something is up and the block test just summed everything up.

 

my waterpump gaskets kept going.
