My husband has dementia and he thinks the temperature on the themostat is too warm. It is in the middle of the dial. I don't want to take the care in if I don't have to.

Will a 98 Oldsmobile bravada hood fit a 98 gmc jimmy?


there was a grinding noise in the motor and the oil gauge went up to 80. When I shut it off, I couldn't get it started again but the grinding noise was still there. After 5 minutes of waiting, I finally got the motor to turn over. Our mechanic cannot find a problem as it does not make the noise now. Afraid to take in on the road. Please help.

At different times of day and night, car security goes off and we have to unlock car and then relock it so that horn will stop blasting. There is no rhyme or reason for this, but we would like to make it stop. Is there a sensitivity adjustment?

I have a coolant leak in my 97' Jimmy. It's more than just a leak, it's a flow. I have located the leak within a small area, but unsure exactly where it is coming from. I have pics of it if needed and the area is about the size of a softball. It seems to be coming from or near these 3 metal hoses that run together. The metal hoses are located on the driver side behind the motor a bit. Does anyone have an idea of what exactly could be leaking?

INCIDENT: How it happened was one night I was driving and the temperature gauge started shooting high, steam/smoke started coming from under the hood. Did some inspecting, obviously coolant is all over the place, but also ONLY a half quart of oil is in the motor?! I had no oil spots in the driveway and the oil gauge didn't warn me. The oil was due to be changed, but not overdue.

I replaced my vacuum booster, had to remove the brake light switch from the pedal but now can't figure out how to remount the switch properly. The brake lights are on all the time. The switch is working ok.

how do I remove and replace the sway bar kinks

my heat is on all the time, it does have the automatic climatic control, what could possibly be the problem

I have a P0410 code , but , Haynes manual shows I have no secondary air injection system . I can't use your normal answer because I don't have a secondary according to my Haynes manual .
Now what do i do ?

Secondary Air Injection System
Just what is the Secondary Air Injection System on this vehicle ?

I inhearited a 95 gmc jimmy 4.3 vortec. When i first got it i replaced the fuel pressure regulator. It ran fine for a few weeks. Now the motor shakes at idle, and all the codes are showing is my downstream. I replaced the downstream sensor. I took off the cat, and someone had already punched everything out so its empty. Local mechanic whom nobody trusts says he did a compression check and thinks its leaking air/compression between cylinders 4 and 6. I have replaced the spark plugs and wires, but not yet the distributor like i should have. Was told to open my radiator cap and if the coolant is shaking than itd deff be the head. I dont want to be driving it, but i have a few times but just 6 miles overall. Where should i start? what should i do? lost and really need this vehicle. HELP PLZ!

the lights come on after the truck has been running for a while. I also hear a high pitched noise when stopping or starting up from a stop; brakes are fine.

Some times the power window on the drive side will not work.

The temp is fine however it dosen't put out air like it did before (just went out a week ago).

Hi, I have noticed when I stop or go over even a small bump the tire near the front passenger side knocks. It started out as a very small knock but today it go a little louder. I have recently replaced the ball joints in the front and back. Any ideas?

I put a new altenater and a new battery in my 1995 gmc jimmy and every time it would start right up and run for good for like five minutes then just cut off. Why is this happening

The tailgate window only goes down part way on one side and seems to bind up. I took off the cover & found some rusted metal pieces/arms? in there. what are they called so I can order the correct parts?

lost power to my speedometer tach radio and some internal lights. checked all the fuses no luck.

ive recently gutted the cat. converter and the TSR but it still wont crank. showing 50lbs. pressure at fuel rail and tries to crank when i spray starter fluid in the breather. Help someone, please.

I went to trade in my car and was told that my transfer case was going to break and it was dangerous. They offered me next to nothing for the car and I'm wondering how much it is to replace a transfer case so I understand how much to reduce the price of the car. THANK YOU

How do I reset the timing on 1999 GMC Jimmy?

Why did my fuel tank over fill and come out the bottom of the car not the nozzle?

my son is unable to shut his truck off without pulling the fuse out. He can literally pull the ignition key out and the dash lights, headlights and truck will continue to run. He doesn't pull the fuse the truck won't shut off and the lights continue to drain the battery.

the drivers side door is sagging and will not shut correctly unless lifted and slammed shut. I read its a common issue with these I am just curious what the repair cost is. Anyone know
