Throttle Body Gasket to Intake manifold leaking Radiator fluid

1996 Pontiac Bonneville SE,

Leaks under Pressure, Just by looking at it, it seems the gasket is warped a little and is pushing out the throttle body, Uhmm..... Any ideals?

If you need more info i will try to tell, I just need a basis on what needs replacing and If i have more then one problem. :<


Thanks

It may be time for a new UIM, but you still need to remove the T/B for inspection, it could just be the gasket/seal.

I recently encountered the same problem, coolant was leaking internally, these cars have a plastic upper intake plenum that melts the egr port, they sell a kit that cost about 70 bucks shipped to fix this, the kits comes with a new updated egr port for the lower intake, a sleeve for the upper plenum, & cold weld. If this is your problem, it's not to hard of a job to tackle.

Can you give more info about this Kit? so that i may look into it more. :)

I feel as though this is the problem.. Seeming with me its never an easy problem.

I will be taking the T/B here in a day or 2, Not sure if im going to take the UIM off

Here's the link http://ken-co.com/manifold/default.htm

It would be much better to order a Dorman replacement # 615180 which comes with an upgraded UIM and all necessary gaskets. Check: http://www.rockauto.com/catalog/raframecatalog.php

Thank you for the information. :)

One more question. :P What is the damaged done by leaving it as is?

One more question. :P What is the damaged done by leaving it as is?If you do have the early symptoms of UIM failure, eventually the inside of the intake & engine could look like the one in the pic below. When it goes this far, major internal engine damage could be the result. :uhoh:

That pic. above is what happened to me, I noticed when my engine hydro-locked from all the coolant filling my cylinders. It's worth the time & effort to do the job before it gets that bad. The site HotZ28 showed you seems like a very easy replacement, I myself enjoyed the challange using the kit I found. But had I known their was a replacment for about the same price, I might have just done that. Make your choice & tell us how everything goes. We need to keep these Bonnys on the road, they don't make them anymore...

Alright I am convinced and will replace it. lol :) Thank you both for you're time and effort, I'm sure i will post again while i have it apart lol, Seeming i am still Inexperienced and will probably need help one way or the other:P

Thanks

is that green coolant i see? you should be using the orange coolant from GM. A mechanic i know has tested the differant coolants the green coolant has a differant ph than the orange. green and orange start at opposite ends of the scale (ph) just treat the orange like we use to treat the green (replace every two years not 100,000 miles) and your gaskets will not fail so easy. acording to him if you leave old coolant in to long it is a slow death to all plastic engine parts.

Ah i see, That pic is not of my car:P I used the Dex coolant although..... This car did sit wrecked for about a year,

When i got it, I believe there was green coolant in it though, I've fixed it and had it runin for about 3 months before transmission went out.< Which the pan was damaged in the crash, Anyways..... The coolant that leaked out of the T/B / UIM was green For Sure:<

Here you go.

Thanks for puting my pics up. :),

Tonedog that looks clean as hell :), I am going to do the same to the upper and lower Intake, by the way... What should i use to clean it?

I took the UIM off today and found that the Gasket where radiator fluid goes through is ripped and messed up lol, and It was all grimy and black, i will post pics, in a day or so.

I got another random question lol... Can the Oil pan be removed without removing anything else? I need to replace the pan and gasket seeming i think both leak lol,

Thanks :)

Thanks, all I used to clean it was a razor blade to remove old gasket material, brake cleaner & rag for the nasty stuff, & triple zero steel wool to polish it up a bit. To release the fuel pressure, , there is a small valve, like the valve stem on a tire, just push it in with a small screwdriver, ("don't spray yourself with gas, use a rag to avoid this".) This valve is located on the front drivers side near the thermostat & upper radiator hose. & for your other question about the oil pan, beside a small piece of plastic cover "part of the transmission flywheel cover" needs to be removed to get to a few bolts for the oil pan, other than that, it does come right off very easily. Make sure everything is clean before installing everything to prevent leaks, this also helps to find future leaks easier.

Alright thank's. :) I edited my last message and made it more up to date before you posted this one. :P I did in fact Spray fuel all over my hand lol but, used baking soda to help remove it, I'll be working alot this week untill monday so i won't have much time to do anything,

I should be posting the pics tamo so you can see what it looks like atm. Its Pretty narly lol,

Sounds good, I'll keep an eye out for those pics... (clean engines are cool running engines), plus you don't get dirty while re-installing everything....clean hands= clean tools :)

Yeah for sure :) From how dirty and grimy it is and the fuel injectors..... OMG lol I'm surprised it even turned on let alone drive lol, I'm going to clean it like it was brand NEW> :)

I like geting Dirty though:<> lol :devilsign:

There it is. :) lol I forgot to take a pic of the gasket :< but, it was ripped pretty bad

If you can tell...................... Both of the inner fuel line bolts broke off lol...... Grrr

Nice, looks alot cleaner than mine did. What did the EGR Port on the upper plenum look like? Was it melted & corroded like the picture I posted of mine? If so, are you planning on replacing or repairing it? Also, what I did to get the coolant out of all the cylinders was disconnected the fuel pump relay, pull all the spark plugs out, & cranked the engine over, & watched it splash everywhere.

how many miles on this engine?

how many miles on this engine?


134k, I However have only put 900 miles on this car since i bought it:

I didn't really spend to much time looking at it:P lol so i don't know but, I am about to go clean it some: IF it is dmg I will be doing it myself> :P

You really think thats a good ideal? lol How many times Should i crank it over? Should i drain any other fluids? And Do you happen to know which relay is the fuel pump lol, Theres 5 relays i think..... but, they aren't labeled.

Well, I know for a fact that it's a bad idea to leave water in the cylinders due to the simple fact that it can sieze the pistons to the block, crank it as many times till theres no more water in the cylinders. The fuel pump relay was located on the passenger side under the dash, when you remove the cover, theres a sticker with the relay locations printed on the underside, I believe it was the top one. As for your other question about the other fluids, I personaly would remove & replace all the coolant, & the oil & filter, due to contamination. PS.... if your sticker is missing for the relay locations under the passenger side panel, let me know & I can pull mine off again to verify for you.

Alright, Thank you .:)

Btw, the EGR Port is Perfectly fine :)
