Hi I need help my 96 Chevy blazer shake when I hit 120km on the highway I don't no much about blazer I just got this blazer but anyways it shakes at the back area of the blazer when I hits 120km does anybody no what the problem might be?

 

Tire out of balance would be my guess.

 

What do I gotta do to fix that?

 

Take it to a tire shop. They'll remove the wheels, balance them and re-install them.

 

K thanks.

 

Hi I'm having problem with my 96 Chevy blazer with the heater it will heat up for awhile then after driving for a couple hours it will just start blowing cold air does anybody now what the problem might be?

 

Low on coolant or a pinched hose

 

Yeah I no it's no low on coolant I checked that it's still good and full so how would I fix a pinched hose if that the problem.

 

My low heat problem was two things. The orange long life antifreeze had plugged the heater core. Also the water pump wasn't pushing enough "flow" to overcome the restriction.

I flushed the entire system including heater core and block several times when I installed water pump and radiator. Now got great heat.

 

Ok I'll give that a try thanks.
