Ignition, warmup idling, everything when I first start up the car is fine, however sometimes after driving for a while or redlining the power feels bit low, cept the temperature guage hasn't gone any higher and is still at 1/2 way. I drive a 86 N/A engine's 34,000 miles cept it's 20 years old, doubt it's gone through a rebuild. So am I just imagining things or could something actually be wrong? Could the engine be overheating, cept as far as I know the temperature gauge works, just not sure how accurately.

 

1/4 up the gauge is normal, im pretty sure that 1/2 is pretty hot

 

so would I need to check my coolant or my intake?

 

Check your thermostat

 

Yeah, I've never seen my GXL temps above 1/3 on the gauge and i dont even have a great rad, and i've driven it pretty hard.

 

1/4 is normal for the S4. Reportedly, the S5 guage is graduated so that 1/2 way up is normal.

I read that if the guage is graduated so that if you actually hit the overheat line, you have been running WAY too hot for way too long.

Ok u guys got me scared for a sec cause my s5 gauge reads half way all the time, so I guess thats normal?

 

Well I added some more coolant in, was on low a bit, took it out for a quick spin, the temperature guage is still holding at 1/2 way, but mine's an S4.

 

if u beat the pants off your car it will heat up .. especialy if u are not giving it sufficent oil ... chech oil pressure iknow my engine had about 180k km on it and if i beat the pants off it for about 15 20 mins not only will i burn almost a half tank of fuel but it will feel dogish ... i have a s4 na aswell ... perhaps its just getting tired ....
