Any Help Will Be Appreciated...

So a buddy of mine has a older Blazer (80s style) not sure what year but it has a 350 in it with the stock radiator. Now the problem is that the radiator is bad and he wants to replace it but hes not sure if he was to get another radiator from a donor car that should fit his truck will it be ok with that paticular engine? I'm not even positive if the radiator is stock but I have no idea what to do. He told me the engine is out of a van if that helps.

Call 1-800-radiator they are really good and have bought alot of radiators from them and they have really good prices

Thanks dude for the help but I'm looking into getting a radiator thats used and as long as it will work with the 350 in the blazer. Now I have question did the blazer in the 80s come with the 350?

Is it an S10 Blazer or a full size?

Good point blazee, if its an s10 blazer i try to find the HD 4.3 radiator. They have an inch and 3/8 core.

I believe that it is a regular full size Blazer not the s10 style but I could be wrong. Tomorrow I'll find out more.

Yeh we ask cuz some of us lol went that route. Wheres my shotgun?

Never buy a used rad.

I replaced the radiator in my 93 S10 Blazer about 3 months ago with a new one which cost about $235 from a radiator shop. The deal was he would find the problem with my old one for free. The old one had a crack, near the top, in the plastic driver's side manifold. This was not a manufactured crack to sell a radiator. Once he pointed out the crack, I could see why the source of my leak was so hard to find. I elected to get a new one from his shop and installed it myself because he was too busy to install the radiator on my schedule.

Replacing the radiator was very easy. Probably, the most time consuming part was draining the old radiator.

Very true.

It is not worth the gamble to install a used rad which could really mess up everything and cost you 1000s.

Especially considering the fact that any used radiator for the vehicle in question would be at least 10 years old.

True, and you don't know if that person took care of the cooling system or even if the rad failed and is the reason that truck is in the boneyard in the first place.

Unless you could get lucky. The rad i pulled from the jyd i found the paperwork in the glovebox for it. That almost never will happen.

Is this the same rad that you said took out the V8? :banghead:

No the one that took out the V8 was the 15 year old POS.GRRR

So I got more info on the Blazer:

91' Chevy Blazer SE with a Automatic Tranny and 4WD. Now again to my real question, since the engine has been replaced with a 350, was the original engine a 350 as well and if so will a replacement rad. for this model work with that engine?

I don't think that the '91 blazers came with a 350. I thought that they had the 4.3 or 2.8 engines only. But, I may be wrong.

If it's a full size Blazer, I believe they came with the option of a 350 or 6.2 diesel, in which case a standard sized replacement radiator would be fine.

How can I tell the difference between a full size and a regular size?

S-10 Blazers are on the same frame and are the same size as the S-10 pickups. the Full Size Blazers are the K5 Blazers, they are built on the same frame as the 1500 trucks.
K5 are significantly larger than the S10s. Not quite as big as the Suburbans, but pretty large. THe S10s are about the same size as your Explorer.

Yeh the full size blazer is a tank.Like bong said its roughly the same size as the xplorer.Can we have a photo?

OMFG I was talking to this guy yesterday and I was repeating the info on his Vehicle and he says no not a 350 a 4.3L. I don't know why he said a 350 before.
