we just flushed the coolant in a 95 del sol and after a test drive the car idled wierd from 1k to 2k. it just jumped between the two. We had the resevoir filled with coolant but put alittle too much in, so we filled the radiator with water, or half way...we really cant tell, and when it sits ideling, it jumps from 1k to 2k. Is this just becuase the coolant needs to circulate through the motor or what?

any help would be great thanks.

 

bump please help

 

recheck your coolant level, you probably had an air pocket in your coolant system. Chances are it's low. Make sure you check the level in the radiator. Good luck.

 

He's right you have air in the system check your level and see if it's low.
Also could thy running it (from cold) with the radiator cap off

 

if its a b-series engine dont take the cap off that wont help theres a bleeder screw for ur coolant on one ur hoses
