okay..so the past few weeks..when i drive my '86 (22R) after it's been sitting for more than a couple hours (long enough for it to cool down all the way) i start it up..and as i'm driving it will start to heat up normal..then it will start climbing up to the red..it never goes above the top white line..but after a little bit of driving it just slowly starts to come back down...and if i flip the switch a couple times from recirculate back to letting air flow in from the outside (..can't remember the name lol) it will start to come down...idk it's weird to me.

thermostat?

radiator problem?

heater hose problem?

 

bad fan clutch?

add a pusher electric fan in front of the raditator.. (keep it cool)

use a laser thermostate and check that way while running

 

could be a sticky thermostat.
clutch fan working properly?
how old is the radiator?
have you been messing with the cooling system lately? or did it just start doing this out of the blue?

 

heyyy...my fan clutch is bad LOL!!! i thought when the fan clutch went bad..it just made the fan spin 100% of the time????

 

ahh 1990 is faster than me lol

 

out of the blue Toyota 1..

and when it got REALLY cold..(single digits..which is cold in oklahoma) the thermostat did stick close..i guess it was cuz i had a LITTLE bit too much water in my coolant mix..i drained some out and put in 100% antifreeze and problem solved..lol

 

copy...

and on the fan ive had them do both, stay engaged and never disengage..
i got a new one from napa for like 30$

 

copy?

and yea i know it's cheap..i just haven't fixed it LOL

 

sorry, we are a lil redneck here on the south coast.

copy = like on a cb radio, got a copy/ copy that lol..

 

OH lmao..oh believe me..i know allll about cb talk lol just didn't think about it like that lol..


guess i'll start with the fan clutch..and prolly a new t-stat just for kicks and giggles lol

 

Sounds exactly like the sticking thermostat problem common with the 22r/e.
New 'stat, stat!

 

just change out everything for good measure
