Question about 2001 Chevrolet Blazer
My transmission was rebuilt 7 months ago. started leaking transmission fluid at the o ring at the radiator. That was fixed last week, now leaking antifreeze. The mechanic is telling me it's the intake gasket...not related to the repair last week. Does this sound correct?
While it is possible, any seal could go at any time, I do not blame you for being suspicious. I would check the intake bolts for a loose one (better done before complaining about second leak - little to no chance for a re-tighten if done on purpose). Note: it is possible for a bolt to loosen on it's own. I also suggest taking the vehicle to another garage and explain the situation to them with a request to look for tampering. You might want to speak with the police before taking any further steps in case they wish a report filed.

Yes, intake gaskets are extremely common with your truck. Unrelated.

You have a coolant leak most likely in the heater core. Try disconnecting your heater hoses and coupling them together, then running the engine to see if the leak goes away. If it does, I would have the heater core replaced.

If the coolant is in the cab they did not cause the problem changing the manifold gasket. It sounds like the heater core has failed, which is under the dash.

No heat is probably a result of low coolant, which basically starves heater core when necessary to feed rest of engine when coolant too low, or an airlock. I really think it's time you took it to a rad shop or similar & had a pressure test done on system & a proper diagnosis. Delaying it will only cost you more, like a whole new engine.

it could but- check passenger side front where heater core line go into manifold right behind alternator the hose line is connected by a press clip into an alloy fitting this fitting gets eaten away by anti freeze and hose angle pulls back on fitting the part is $18 at dealer and is screwed into manifold use caution if ur r going to replace at very edge of aluminum manifold---and check ur water pump bolts the 2 longer ones should have a lock sealant on them they bolt in thru a water jacket

Make sure you don not run low on transmission fluid in your transmission. Low transmission fluid will cost you a new transmission. You have the transmission line that connects to the upper passenger side or the radiator and the lower passenger side of the radiator. Determine which line has gone bad and you can buy a rubber transmission line hose at most Auto Parts store like Parts Source. Cut off out the section with a pipe cutter that has corroded through and replace with the transmission hose. Make sure you tell them it's a transmission line hose your looking for and don't use any other hose and double clamp with a compression clamps at ether end. If it's the connection at the radiator that has gone bad, replace that end and do that same as you would to sectioning off the the corroded line and try not to have more then 3 inches of repaired section. What ever you do, do not add any stop leak, this will create problems with the shift solenoids and check valves in your valve body in the transmission causing a transmission replacement soon after adding. Good luck and keep me posted.
