it takes about 2 to 3 hrs. Well if it takes you 3 hours, there is a problem. an hour tops
Had same problem with My 91 Lumina APV. Changed Starter Relay. Haven't had any problems sence.
As long as it is in the "normal" range
The majority of the 93 Chevy Lumina vans requires a size 14 tires. A size 17 would not fit properly on the van. While you can spend extra money to have the van altered to fit the tires, it isn't worth it in the long run.
Head gaskets are supposed to last the life of the engine. There is no "care" specific to head gaskets.
If you know what your doing its takes about 1.5 hrs.
not quit positive
If your oil light's on, you should have added oil a long time ago. Check your oil and see if it even registers on the dipstick.
I would say as long as you have the right tools and then know how to bleed the lines after you should be fine
look at you thermostat sticking that happened to me in my 79 chev or check for plugs in rad
