85 SR5 Toyota overheating

[peach1012]

HAVE U FIXED THIS YET???

HEY I HAVE A QUESTION DO YOU NEED TO ADD WATER EVERY DAY???
iF THERES A YES AFTER THAT THEN...

WELL.... ITS THE HEAD GASKET

DONT WORRY THIS HEAD ARE EASY TO TAKE APART i HAVE A FACTORY SERVICE MANUAL THAT I GOT SCANNED SO ITS ON MY PC IF YOU NEED INFO I CAN EMAIL IT TO YOU

BACK TO YOUR PROBLEM

IF THERE WAS A NO TO THE FIRST QUESTION
THEN IT COULD BEE THIS...

THESE TOYO'S HAVE A WEIRED EFI CHANMBER WERE A NATORIOUS AIR POCKET GETS STUCK... RIGHT UNDER YOUR THROTTLE BODY YOU'LL SEE TO SENSORS ONE IS FOR YOUR TEMP. AND ODER...

CANT REMEBER OF THE TOP OF THE HEAD

THATS WERE THE AIR POCKET FORMS AND IT WILL MAKE THE SENSOR GIVE YOU BAD READINGS... IT WILL MAKE YOUR TEMP. GAUGE SHOOT UP LIKE YOU MENTION...

IN ORDER TO FIX THIS...

IDLE YOUR TRUCK WITH THE RADIATOR CAP OF
(KEEP AN EYE ON THE TEMP GAUGE)
IT SHOULD TAKE ABOUT 5-10 MIN DEPENDING HOW BIG THE AIR POCKET YOU HAVE
IF ITS A BIG AIR POCKET THEN YOUR GUNNA SEE SOME GUSHING SO WERE SOME GOOGLES OR AT LEAST SOME SUNGLASSES
(LOOK COOL AND BE SAFE )

WHAT I LIKE TO DO SO IT DONT GUSH IS DRAIN JUST ENOUGH WATER OUT OF THE RAIDATOR SO I CAN SEE THE FINS INSIDE AND STAND READY WHEN THE T-STAT OPENS AND ADD WATER, BUT IF YOU MISS IT THEN YOU JUST MADE A BIGER AIR POCKET

YOULL KNOW WHEN ITS DONE BEACUSE YOUR IDLE WILL BE SMOOTH
THE REASON WHY YOUR IDLE IS ROUGH IS BEACUSE YOUR AIR VALVE
IS ALSO GETTING WEIRED SIGNALS

GOOD LUCK

When it truck is at normal running temp open the hood and look at the fan clutch now when you turn off the engine it's not suppose to keep turning for very long if it does the clutch is bad also look for signs of oil around if it has some that means it's bad. Check that your hoses are not collapsing that will restrict the water from flowing and last over heating a engine takes a lot of years off an engine so fix it quick. A compression test will find out if you have a bad head gasket many years ago they had this kit that you could place something by your tailpipe and it could tell you if you have a bad head gasket those kits were used when GM used 5.7 engines for diesels they were bad for blowing gaskets maybe a GM dealership still has that kit.
Good luck! GMC
