Back after 12 years
Hey I just bought my second LX 5.0 this time a 1990. I had a 1989 12 years ago. This car is very modded and I am having a over heating problem. I think my set up might be to much for a OEM radiator which it has. Here is a list of my mods.
Vortech V-1 supercharger 8 psi
Anderson style powerpipe
42lbs injectors
Lightning MAF
GT40 heads, with upgraded springs and 3 way valve job.
Scorpion 1.6 full roller rockers
Manley hardened pushrods
GT40 upper and lower intake
JCP custom cam
Accufab 70mm throttlebody and spacer
New Melling oil pump with new ARP pump drive
Aermotive stealth 340LPH fuel pump
Kirban adjustable fuel regulator
BBK crome unequal headers
BBK O/R H pipe
Magnaflow mufflers
Gripp rear upper and lower control arms
Welded subframe connectors
Welded Panhard bar
Aluminum driveshaft
355 gears
275's and 255's Nitto
Lowered and aftermarket shocks
T5
OEM clutch
The previous owner said the supercharger has only been on the car for about 200 miles. After about 20 minutes the car over heats. I replaced the radiator cap. I only saw some water that had leaked around the edge of the hood and battery area. Each time it over heats I need to put about half a gallon into the radiator. After a 10 minute ride today I put it on ramps and saw no leaks under the car around the water pump and hoses. Also the car didn't leak out any fluid and the overflow tank was at normal level. When the car does over heat the overflow tank is about 3 inches from the top and somewhere under load coolant leaks out. The OEM radiator I have is in good condition. Can a OEM radiator handle my set up? I just got it on the road this week...

thanks for the reply the problem was air in the system. However about a week ago with only driving the car for about a week since I got it registered it started to run absolutely horrible. Oil looks good at the dip stick so dose not appear to be a head gasket. Barely will idle and it flutters significantly. I cleaned my mass air sensor. I'm 2 weeks out from a reputable shop to look at it. I'm wondering about how the programming/ chip it is. I learned few shops are confident to look at it. I'm very anxious to find out what is going on with the car. I'm wondering if I would be better off taking off the supercharger for reliability? Also I live in northern Florida and am looking for experienced foxbody mechanics in the area?
