Autozone have some popular workshop manuals for free on line once you register (for free) on their website There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
Alldata is great you will like it.
thanks for the info,would still like some input on my problem.radiator also builds pressure but the waters not hot enough to burn you ,gauge says about 195
You have a blend door that controls heat. That door is controlled by a blend door actuator. Do you automatic temp or manual control?
its manual control any way to make sure its the dash control without the process of elimination or the door actuator thank again
