After 95AquaC4 found a $20 bill in his radiator, I figured I'd look for my $20! (Especially after it heated to 230 degrees in 105 degree stop-and-go traffic this week.)
Here's what I found...

Leaves : Several, some shredded and some whole
Plastic Bag: One, Grocery story variety, well shredded
Sand: One tablespoon full
Blockbuster Receipt: One, (couldn't read the rented item but I'll bet it was Saturday Night Fever or maybe Top Gun )

No $20 bill! I guess that was only an option on the 95's :nonod: :sad:

 

That's not bad for an 87 unless you've been in there before? I had so much sand-gravel-dirt that it instead caused $20 damage to the radiator. :lol:

 

I'm having some overheating issues as well on my 86 and don't know if the radiator has ever been thoroughly cleaned in 150k. I'd be interested in knowing some of the details of your cleaning job. How long did it take? Easy-difficult? Tools, materials? Pitfalls? Thanks in advance.

 

Yeah, all that I found was a HUGE leaf........no $$$$$ this time!!!!!

 

I got hosed on this deal as well, all I got was two gum wrappers and a maple leaf :(

 

Look at your build sheet...you need to have an RPO # 2X10...

 

Charlutz,
Took about 3 hours this morning. Go to the C4 tips area and print out the tip sheet on "Cleaning your Radiator". It gives you everything you need to know. Not too bad a job as Corvette tasks go. 5/8, 7mm & 10mm sockets, 1/2-9/16 flare wrench, screwdriver. Pretty strainghtforward and the instructions were great! Go for it!
:seeya

 

My pile from my 88 was twice that size. Bet I had all the leaves from one tree in it.

Its pretty easy to get out in the L98's. Plan on flushing the cooling system and replacing any bad hoses at the same time. Also remove and CLEAN your recovery tank. Lots of folks have found them to be real nasty and clogged up!

I just removed the upper radiator shroud, the automatic transmission lines, the upper and lower radiator hoses.
Biggest pain was getting the accumulator for the AC out of the way.
When everything is disconnected pull the empty radiator out. Clean out the space.
Clean the outside of the radiator (simple green or dish detergent).
rinse it out thoroughly
Flush the cooling system and replace hoses (thermostat as well while you are at it)
Put it back in , put the shroud back on, hook up all the hoses
BE CAREFUL with the AT lines. Snug + 1/4 turn should be enough for it not to leak.

Now fill it with 1 bottle water wetter (before adding the 50/50 mix) and a 50/50 mix of DISTILLED water and anti-freeze (green stuff). Run the engine for a while until the thermostat opens and fill it some more. Fill the recovery tank 1/2 full with the same mixture. Finish off with a new radiator cap.

Took me about 2 hours (took my time, observed where everything went, had to clean a nasty recovery tank, etc.). Good Luck!

I need to do that to my cars. :yesnod:

 

Thanks jaa and ramjet. :cheers:

 

I do mine in spring just before the hot weather hits and in the late fall just after most leaves are down,, .......I never got a 20 dollar bill but I bet I saved a bunch. Anyway the first time is the hardest and you will see little things you can modify to make the job easier .......I modified my upper shroud for easy removal and the changes don't show.......much....... :seeya
