1. Car idles at at 1500 - 1600 back n forth n sounds retarded.

2. Engine heats up really fast, i drive it for about 15 to 45 mins the temp stays at normal temps, but then its starts rising then going down the rockets back up again...

as for problem #1 i dont know where to start.

as for #2 flush the radiator, check the thermo, replace the fan cuase i think thats the main problem i dont hear it start up.

btw how do u guys flush your radiatior?

 

go to any pep boys or walmart autozone......ect.

the have radiator flushing things you can buy and they have instructions on them...i would have to recomend those because it cleans your radiator.

also the same thing happend to my teggi way back when and the cause of it was a cracked radiator

so you might wanna check that
