Engine Cooling problem
1997 Toyota 4Runner 6 cyl Two Wheel Drive Automatic 171118 miles
I just had eng replaced 1 month ago with used 1 after head was ruined, silicone blocked the oil ports to lft/head. Well anyways, the replacement 5vz? Eng, runs good but the radiator is much hotter than it use to be with the origianl eng. It has boiling pressure when removing the radiator cap, and uses all the coolant in the reserve tank as well. I just did the oil change and didn't notice any coolant in the oil. But the coolant was about 1+ quart low in the radiator and empty in the reserve tank. I had these topped off 3 weeks before and never noticed any excessive coolant use before. It seems as a reverse sucking pressure is taking effect. The mechanic that replaced the eng, wasn't the brightest. The only new parts are the heater control valve, w/pump/plugs/wires/belts and I'm not even sure hat the eng is an exact 5vz eng, replacement? He gave no serial #'s just said that the eng was a 2002 5vz things kind of turned sour. What do you say about the coolant issue.
have the same problem?
