my gf 91 tercel is in the shop
the guy (fairly reliable) said the cooling system pressure is too high and it would cost $800-$900 to fix
the engine shakes and some black liquid comes out the exhaust and i thought it was a bad cylinder
anyhow i was wondering if this estimate sounds right and if its worth it to fix
it was rear ended about 2 months ago and she doesnt want it anymore but is in a tight money situation
