Problem for Toyota 1991 Pickup
1991 4 cyl overheating
By maartenw - usenet poster
Hey all,
A friend has a 1991 pickup 4wd w/a 4 cyl. 140,000 miles It has been
overheating constantly recently. He has replaced the theromstat, and
many waterpumps( after he bought and tried a rebuilt, he bought a new
generic, then a new Toyota w.p.) to no avail. The radiator has been
rodded for clear passages.
He can drive it easily around,w/o incident. Unfortunately, the road to
his home is uphill about 1.5 miles, by the time he geta back home the
truck is spewing it's guts. I thought there might be a head gasket
problem.
Is there anyone else that has this problem??? could there be an inherent
design problem??
Any comments or thoughts would be appreciated
Thanx in advance

If it has an electric fan, check the fan motor and the coolant temp
sensor and the fan wiring.

that's a very reliable engine. I've got 185k on mine with no problems.
Some folks have made it twice that.
Friend with an older model went crazy swapping stuff only to find out the
lower rad hose had come apart and the spring was interfering with the
water flow. a long shot. spewing sounds serious. i'd also check for exhaust
in coolant - head gasket or cracked head.

I had the same problem. I replaced the radiator purchased from NAPA for $125 that solved the problem. The old ones cooling ability was reduced from radiator stop leak

Sounds like it could be the fan clutch. They're easily damaged.

Where does it spew from ? How old is the radiator cap? How much
anti-freeze fluid does he use? It might be possible there is an air bubble
in the coolant line somewhere. If there is steam coming out the exhaust
pipe, it is a cracked head and the engine would not run very long when super
hot.

Hi !
Check your coolant for oil mix or your spark plug for green spot, this could
be your head gasket. Check your fan for good operating temperature. This
could be a defective temp sensor or a defective thermostatic fan.
