my 1999 deville was telling me that i needed to check the coolant level. I ignored it for a little because I didn't want to hear the price of repair for a new engine. When I tried to take it in the car was overheating, no doubt about it - 240 degree. I had her towed in.

The work thats being done (im going to keep it vague cause I have NO idea what it is): he replaced the hoses and something to do with the housing and valve. its going to cost me 1,100 and it was 6hrs worth of work. I no longer have a coolant leak though.(what the mechanic said, I'm wondering if this means I'm safe for HG repairs)

My checkup... when he was pulling codes and resetting them my ac code had came up a few times. He checked it out and noticed it was low. He said he put some dye in there and topped it off, to drive it around and come back in a couple weeks so he can visually see where the leak is going to.

All of this is being done at the dealership.

My concern as of right now would be my head gaskets. I'd rather sell it/trade it before I have a huge lawn ornament.

If you are not using coolant or overheating after the repair, then the HG's are fine.

thanks for the reply. Just picked her up today and shes running smooth. I still feel like I'm sitting on a ticking time bomb though.

Even though the car is running good and you see no coolant leaks under the car, keep an eye on the coolant level in the expansion tank.
If it keeps losing small amounts of coolant and you find the need to constantly add coolant....Be afraid,..be very afraid.

Northstar engine can be running like a top and show no coolant leaks BUT still have a blown H/G.

I wonder what work has been done with $1,100?
I'm just going to list the part # as the hand writing is not the best in the world.

251.660 - Pump? - $150.00
251-647 - gst hsg?? - $25.00
251-627 - gst hsg?? - $25.00
40-731 - TBgskt?? - $12.00
3542601 - tbgskt?? - $10.00
126131164 - tst.hsg? - $120.00
1639094 - hose - $19.00
pg-61?? - o. fitted?? - $7.50
12346303 - dye - $12.51
1434a - h34a - 46.00


$16.00 for 8 qts of oil

labor was $90 an hr?(was told that previously the first time I went there) - $605.00


it all came to 1126.72 either way. My cars idling coolant temp climbed a little earlier on today, but driving it was steady at 201. I also have heat/ac again and the check coolant warning didn't come up. Can't complain, really.


@ caoiii

how would I check the coolant level? or keep an eye on it? I'm not even sure how to add it..tbh.

I am guessing your water pump was leaking, and also he replaced some thermostat components (price looks like the housing & cover.) How would you rate your mechanical skills? Water pump / thermostat are definite DIY jobs for an entry level home mechanic.

Your coolant surge tank has no window to look at the coolant level so you need to look through the fill hole. Keep the level 2 inch below the fill neck. Don't top it off or it will start pushing all the excessive coolant out of the car and/or start overheating.

my mechanical skills are next to nothing. I've never worked under a car before. I think the most indepth thing I've done to my car was clean the throttle body, but the post on here had pics :)
