I installed an iso thermal plenum spacer 2 nights ago. easy as can be for the install. First night it was fine, but since yesterday when i start the car up in the morining, my heat gauge will go to almost "H" on the scale and move up and down for about 20- 30 minutes unless I am driving on the highway! also I think I hear that my radiator fan is almost always on!!!!!! can someone help me with this? After I drive for close to 1/2 an hour or so it goes back to where it was before on the gauge (1/4 the way up), or when Im on the highway it is fine also. But at a stop its running really hot. Has anyone else had this problem? Someone help?!!?>!?>!@#@

 

Installed mine about 5 days ago and still running real strong and great, dont even think there were any leaks, or at least i couldnt tell. In another 2 days im going back and retorquing to see where they sit as far as torque goes, should be good as far as im concerned

 

That sounds like you got air your cooling system not a problem with the spacer. I had air trapped in my radiator and it made my temp go from normal to H and then back down. It fluctuated like that until I got all the air out. I released it by opening the radiator cap once the car had cooled down.

 

thanks for the info, ill try it and then get back if that the problem

 

either air or your just leaking coolant somewhere.. leave the rad cap open and squeeze on any rad tubs.. squeeze it at the highes tpoint and this will push the air out a lot quicker.

 

Also it can be your Thermostat. They suck. So after you get all the air out of your cooling system see if that helps.

 

thanks for the info, everythins is good now, jsut air in the system. and your right, what a bastard to get out! anywhoot forum members to the resque again.
