hi just got myself an import gc8 wrx. had it a few days and noticed it dumping coolant from the passenger side wheel arch. only does it after a long run and when the engine is switched off. usually only notice it when i put the car away at night and in the morning the coolants there on the floor. my rx used to do a similar thing this was because the coolant bottle cap seal was leaking. could this be the cause ? any ideas ?

also noticed a boost problem. the boost seems to build and drop fluctuating quite rapidly. ?

 

The only time my car has lost coolant from that area was when the head gaskets had gone, the coolant will probably be coming from the oveflow bottle by the front of the nearside wing, after a run if you open the bonnet and look in the bottle and see bubbles then you may have a problem.

 

marvelous. thanks for the help
