What could cause my 2003 wrx's temp gauge to be going crazy?

its overheating.

i.e. the engine is getting too hot

Wey a kna that! Wht cud be causing it! Water level is fine! Dont think the head gaskets have blown!

air lock in the cooling system, first port of call would be to get shot of the airlock and top the coolant up etc and see what happens after that.

If it persists then I'd be inclined to do a sniff test on the coolant to rule out potential headgasket issues

Check your header tank for any leaks as well. Mine was overheating due to a small hole in the neck of the header tank.

When is it overheating? All the time, sat in traffic? Etc.

Rutt_Dj

Iv burped the car! I cant see any leaks! My heaters are working fine! But my car is still over heating!

Iv just drove about 20 mins and the temp gauge was all the way up!

Check your thermostat.

same prob with mine, mines the ej20 lump though

Rutt_Dj

Mines a ej20 aswell!

Where is the thermostat? Nd how would i check it?

little-chris

remove teh hose at the bottom right side of radiator , the thermostat is in the hole at teh other end of teh pipe which connects to water pump
