car:95 lt1 6speed
problem:car has 160 t-stat and ewp and runs hot around town past 210 only around town, took the car on 20 mile highway jog at 70mph and it runs between 160 and 190. I just changed to ewp and brand new opti w/160 t-stat. Whats going on here? My car is 13years old; are the stock dual cat(yes dual cats w/OBD 1 computer) clogged or is the problem cooling only?

some one with personnel experience please comment

the ewp is a summit electric pump that was on sale and brand spankin new

 

210 is FINE when idling.. Its when it gets much higher like 230+ is when u worry a bit.

I have heard EWPs will keep the idling temps down, so I'm not sure about that,.

 

CSR ewp here with a 160* failsafe and mine never gets above 180*, even ideling around town in 90* heat. I'm also running about 11.5 compression too on a .30 overbore. Your car shouln't be running that hot IMHO

 

How's the rad in the car? I replaced mine two years ago, and noticed about a 15 - 20 degree temp drop in town.

Highway driving is always cooler, as there is much more cold air flowing over the rad.

 

If you haven't changed the fan temps, then it sounds normal - nothing to worry about.

 

^^ x2 also would not having the front air damn make you car run a little warmer as well?

 

OH YES! The airdam is probably the single most effective piece for cooling on these cars

When I bought my car, some idiot had taken the air dam off before. The car ran so hot, even on the highway ~210 in mid summer sometimes. Bought one on ebay for like $10. Temps have been perfect since pretty much. I stay right around 180 cruising.

 

I got a 160, EWP and mine never hits more then 180-190

 

As Snackeoiler said, it's normal operation stock fans don't cut on till around 235* so the 160 t-stat only works when running cool air through the air dam to rad at higher speed. You need programming or a fan switch to take advantage of the lower t-stat in traffic. Putting on the air conditioner will force low speed fans to run and cool it down a little.

 

How do you have your ewp wired? With a relay? or what? if a relay how did you wire it to turn off and on?

 

Need to get your computer tuned for the fans if you haven't already done so. I run Meziere and a 160 with stock radiator and it stays @170 and may get up to 185 here in Texas on a hot summer day. Never over 200.

 

get you fans tuned for a 160 and you will be good

 

i also have a 160* and my fans are tuned, but my car still runs about 200-205 cruising in town...highway maybe 195. I guess i do need to get a air dam...i feel stupid
