Question about 1991 Isuzu Stylus

1 Answer

I have a 91 Isuzu Stylus xs DOHC, i traded my buick that was having electronical issues. It was over heating, so we pulled the heater core and found that it was put in backwards, then also come to find out the some where in the cooling system there is a clog we are fixing that but the major issue we have with it is power. put it in 1st gear, and let off the clutch and it goes turtle speed till it hits 2500 rpm, then it takes off but when it started get hot none of the gears had power had to rev the engine over 2500 just to get it to move. other than that the body is perfect, and the interior is almost emaculent, has no tick or knock in the motor and unfortunately i can't find a repair manual for it that i can afford. i want to keep the car just don't know much about it as i did my 72 dodge adventurer, and 85 ram charger. (Had a baby had to get rid of my toys). any suggestions will help thanx Catherine

Has it had a recent cambelt change(timing belt)? Sounds like the symptoms indicate your engine timing is wrong!

    As far as i know it has not had a cambelt change. We found that the negative battery cable was loose so we fixed that and it seemed to have a bit more power till you turn on the ac then forget it the car doesn't want to take off. i bought it mainly cause i thought we could fix it and there was nothing wrong with the ac. i am clueless.

    Maybe the cambelt has skipped a tooth to put the timing out or maybe the ignition timing is out! The ignition timing would be the first point to check!

I just put a bypass hose on my 91 Buick lasbre and turn on the heat and started seeing steam come out the vents and now its steam on my windshield

Sounds like you have a bad heater core or you have antifreeze leaking in the into the heater box. Maybe a loose clamp on the bypass hose or maybe you damaged the heater core tube when you installed or removed the bypass hose and now it is not sealing properly.

Timing marks on 1.6 dual over head cam

the geo storm, 1.6 DOHC
the FSM cover it, so does
hint 2, its an Isuzu engine.
its really (makes information easier to find )
4XE1-UW a DOHC 16-valve engine with 130 hp (97 kW)
he DOHC engine was used in the 1990-1991 Isuzu Impulse XS, in the 1990-1991 Isuzu Stylus XS, in the 1990-1991 Geo Storm GSi, and the M100 Lotus Elan.
all that off the wiki,,
all cars rare here.....

1st google hit

This engine is interference type
so when timed, with a new belt
roll engine by hand, with spark plugs out.? do pistons hit valves.
yes, stop, the cam is timed wrong.
no, do a compression test on #1, if pass, do all 4. 150psi min.w.o.t.
wide open throttle
a better test, is a leak down test. x4. by hand.
these acts of kindness to the engine, saves most engines.

if the leak down fails, the timing is wrong, or the valves are already
dont use a fleabay china belt, bet a GATES belt. (they last)
setting the tension is very important to a full life .

I have a 1991 buick rivera it has no heat from the heater. I have had the cooling system flushed. I changed the temp control module.But nothing Changed.wife getting cold in tennessee winter need help.does...

Sounds like a bad heater element switch or heater core. Sound like the heater control switch. On the front side of the heater core you should find a plug. Pull the plug and remove the two screw. The switch should come out. Replace it.

I need to replace a heater core in a 91 buick regal and need to know where it is?

The heater core is going to be in the heat duct either under the glovebox (inside the car) or on same side of car under the hood close to the firewall.

Lack of heat

Sadly "there" explanation is probly correct, when you say you have some but not alot of heat on low and then almost non on high, that is due to a plugged heater core. A heater core acts as a miniature radiator inside your cab. When the fan passes the air by it it picks up the heat and blows that into the cab. While doing that it also cools down the heater core. The more are you pass by it the cooler the core gets. What you can try first before replacing it is a coolant flush. This will run a mild acid like sollution through your entire cooling system. Sometimes that alone is enough to let more hot antifreeze run into your heater core thus giving you more heat. Another option is to disconect both lines into your heater core from in the engine compartment and run a hose into one , leaving the other to drain out. Depending on how plugged it is sometimes you can "Flush" out the buildup this way as well. G'luck and keep warm!
