Hello All, a newbe here

[wayne64]

I am in charge of maintaining quite a few vehicles and the Girl Friends 96 S10 came up with the typical no heat. She bought it last summer with just over 100K on it and all I've done is the oil changes, filters etc. Felt the hoses and they are just warm so I suspect the core is clogged (temp OK) I then found this great site and read though 15 pages of posts and it seems this is a common problem. The cap looks orginal GM and that will get changed along with a flush next week. Thanks to all for the info. Now I would like to share a thing I do with all my rides, I'm not posting this to start anything as besides my other toys I do have a Corvette 350 TPI powered XJS Jag that I built.

It seems I don't have any photos of the Jag as a file, I will correct that as soon as it's winter's sleep is over. We are in the middle of a blizzard right now But here is what I did with the V-12 that was removed.

Good Idea, a table like that would sure go good in my shop

Just a stupid question,,,,, If BOTH hoses were warm, have you checked your thermostat? You never mentioned it.

Not stupid at all, they are both the same temp (way to cool) and this is why I think the flow is almost completely blocked. I should been clearer in the first post about the systems coolant temperature, instead of just saying (temp OK). Had to run to the airport this am and even at 70mph and 12 degrees the needle was sitting around 190. Air bound shouldn't be an issue as today was the first time I pulled the AC Delco cap and the rad was full. My younger son has the same no heat problem with his 95 Caprice 9C1 police package. He blames the LT4 alloy heads he put on, but now that my education improves about the dexcool we need to have a talk.

the bi pass thing is kinda cool, i have a vaccume leak so i just shut mine off in the summer (meaning i put a ball valve onto the in hose of my rad core), are you saying thats bad?

Flush the heater core, probably blocked.... Then do a complete system flush and replace with normal green stuff.

Haha are you serious? Lets see flush a dex cool system then replace it w/ a normal coolant. haha wow im guessing you have never seen what happens when you do this? You cant do that on a 96. Its ok to go from green to dex but you cant go dex to green. Dex is one of the best coolants, short of G-05. As long as you take care of dex it does not gel up. Replace the radiator cap every 30k and you'll be cool.
hope you didnt flush yours w/ green rlith. Or your going to run into BIG problems down the road.

You've got to be kidding..... A lot of us have gone from dex-sludge back to green. In fact 2 dealerships locally offer the option. Several friends that have bought new trucks have had the dealership do this prior to delivery. Absolutely nothing wrong with switching out coolants as long as the previous stuff is completely flushed...

Well have fun with that, in a couple of years you will see what happens when you put a Hightly corrosive coolant in a system designed for non corrosive. Ive seen this in my industry. green will eat your heater core away and your radiator as well as your headgasket. have fun when your trucks F**KED.

okay guys along that coolant thing... so we shouldnt put the normal green stuff in a s-10...i have a 98 s-10 and i added coolant once of the green kind...was the bad...what should i do..and where can i get that other coolant

[dmbrisket 51]

verry verry verry bad, when dex and green mix they will foam up, flush your system (a flush kit is under $5 at advanced auto or equiv.) and put in Dex-Cool from advanced auto or autozon is where i get it, im sure other automotive stores carry it

[bnrboy775]

well shit i wish i knew that when i bought the truck...

[bnrboy775]

but thanks for you help
