89 cavalier from my uncle

Home  \  Domestic Cars  \  89 cavalier from my uncle

I just got an 89 cavalier from my uncle for free. i have to do some work on it my self. It will not hold coolant and it has been sittting for 3+ years. Should i be worried about a cracked block or could it be freeze plugs? :ohcrap:

What motor?

Freeze plugs should be the last thing you should worry about, there's never a problem with them. Cracked block is also very un-common, so those you shouldn't worry about.

2.8 and 3.1's were really bad for head gaskets. That's most likely what your problem is. It also could be something as simple as a coolant hose, or could be your heater core even.

Does the car start? Does it run quite bad? Is the exaust really white? Does the exaust have a "sweet" smell to it?

the car runs well although i never payed attention to the exhaust or the smell of it. i have a 2.8 liter straight 4. I live in illinois and i have cold winters so i was worried about a cracked block. I sure hope it's not the head gasket :ohcrap: :guns: :cussing:

GM didn't make a 2.8 I4, the 2.8 is a V6. So I'm guessing you're talking about the 2.8 V6.

I'd put my money on it being the headgasket since you have that engine, I've done 2 or 3 on mine. Blew up my old motor because I tried to get it home with a blown head gasket, so I've been through a lot of them. It's not so bad once you've done a few of them, only takes me about 4 hours to do mine now. The front one that is. I had to do the one against the firewall on a Cavalier not too long ago, wow, that was a lot of work, that engine compartement was horribly designed. To get the fan out you have to dis-assemble the air-cleaner, and take out the battery and sneak it through where the battery sits. Just an example of how well designed they were :banghead:

i'm absolutely sure that it's a I4, but it's 2.2 sorry my mistake

My info shows that in 1989 you could only get a 2.0L L4 or 2.8L V6...

Turns out who gives a flying leap about displacement when its not the head gasket but the heater core. Figured it out when we got it up on a lift and saw the runnoff from the overflow tank from the heater core. so instead of 120 for a gasket kit, it's just about 50 bucks for all the core and hoses. Yay! :thumbs:
