Replying to: cmac8874 (Sep 28, 2008 5:42 pm) I had a 2000 S10 extended cab with the same engime. It had a leak from the intake manifold gasket. The truck never overheated but did lose coolant. Cost like $300 to $400 to fix if I recall correctly. Good luck.

Replying to: gonogo (Jun 01, 2008 7:17 am) I've got some issues with my sonoma its a 2000 with 185,000 miles. its been in one crash(not my fault). had some body work and new chip(registers E-brake and ABS gauge). But now im getting overheating issues within the first couple minutes of driving. spikes to (260). I thought it was leaking and replaced the hose/valve running rome radiator to engine. today when i turned it off i smelt anti-freeze and heard a sizzling sound? any thoughts?
#17 of 36 Overheating by sniperwaffles Nov 04, 2008 (1:18 pm)
hey i have a 2000 GMC sonoma and everytime I drive it. The temperature guage is spiking up into the 260 range? once I stopped and popped the hood i could smell anti-freeze and heard a sizzling sound. As if something is leaking and the engine is so hot it fry's the liquid. I've replaced the hose going from radiator to engine. Also checked the valve that connects the hose to the engine. that fixed the problem for a while now the problem has returned. (2nd time with the sizzling-1st without) Sny suggestions??
#18 of 36 Coolant Leak: Unknown Part Name For Leaking Coolant Pipe by freddy0872 Nov 10, 2008 (4:20 pm)
I have a 1998 Chevy S-10 with a 2.2L Engine. There is a steel pipe on the top of the engine towards the drivers side. It is mounted down with one bolt on the back side and held into the thermostat housing on the front. It also contains the Coolant Temperature Sensor right before the thermostat housing. And on the back side of the pipe there is a rubber hose that has engine labeled on it. This steel pipe is leaking and i need to buy a new one to replace it. What exactly is the name for this pipe so the guys at the auto parts store can look it up for me. Any help is greatly appreciated. Thanks Freddy

Replying to: cachevy (Jul 30, 2008 4:35 pm) This sounds identical to the problems I have had with my 2000 s10. The dexcool stuff is terrible and GM recently settled a class action lawsuit giving most truck owners 50 to 300 hundred for repairs. Did you fix your intake leak or?? Just curious as I now have one as well. Replies to this message: gonogo (Jan 12, 2009 8:45 am)

Replying to: berto01 (Jan 11, 2009 8:24 am) That leak happens now and then, not yet on my 99, but only 55K. Just buy a new pipe and housing assy, it should be available after market.
#21 of 36 Cooling Problems by bcrawf53 Feb 25, 2009 (6:27 pm)
I flushed the cooling system and replaced thermostate on my 2002 GMC Sonoma with79,000 miles on it.  I've had nothing but probems after that. Service engine light came on, did diagnostic - water temp below engine temp. Replaced temprature sending unit. Same thing? I have to drive 10 miles before engine reaches operating temp?

#24 of 36 99 GMC Sonoma by peter931 Mar 08, 2009 (2:50 pm)
After RR radiator and water pump on GMC Sonoma 4.3L coolant is leaking to oil pan. Truck is not smoking and compression is good on each cylinder. What could be the problem? Replies to this message: bcrawf53 (Mar 08, 2009 6:43 pm)
