changed radiator due to crack, heater core hoses due to leaking. motor was timeserted 2 years ago.did the block test and it came out negative. i am losing a little bit of coolant from time to time. its starting to drive me nuts.
The tabs arent to be used anymore, they clog heater coresIt sounds like he doesn't know where the leak is coming from. Hence, all the part replacements and other work he's done.
I'm assuming it's his 97 Eldo that is having the leak.
My 2003 was constantly leaking a little bit of coolant after the last coolant change, but it looks like adding Bar's Leaks solved the problem. According to GM, adding this kind of thing is *required* even on my 2003.
Turbol15, did you use the GM Coolant Supplement?
For the 1997 Eldo, the Factory Service Manual says this:
"Notice: The 4.6L engine uses DEX-COOL® and GM coolant supplement (sealant) P/N 3634621 specifically designed for use in aluminum engines. Failure to use the engine coolant supplement (sealant) and the approved coolant antifreeze could result in major engine damage. When refilling the cooling system, add three pellets of the engine coolant supplement sealant GM P/N 3634621 to lower the radiator hose."
They did. Don't use that crap.i thought they did away with putting tablets in the coolant system?
Only for the N* right?They did. Don't use that crap.
