No timing belt, it has chain and gears.
as with me, a little screw had dropped down on the piston, tapping on the head while running.

2001 Blazer Replaced heater core now water pump is squealing and seems like low circulation


my 98 Blazer I had to replace radiator water pump heatercore and hoses. Had head gasket go. Once that happens air and dexcool corrode cooling system. Do you smell antifreeze? Are you loosing antifreeze? Check oil see if its another color not clear or black but i think light brown. Have you flushed out system?

Car started knocking really bad got a cylinder 2 misfire code after opening coolant bleed valve with enging hot


Okay, it may be due to overheating, that may be the noise you heard, lets hope. first allow engine to cool, open radiator cap or the resivoir cap, which ever is the fill, remove the bleeder at top hose and fill radiator slowly until coolant comes out bleeder.

note if water pump was replaced due to leaking and engine was overheated at that time then it may be a good idea to replace the thermostat .
after filling is done start engine and allow it to run. watch temperature if temp start to climb past half way shut engine down and let sit for 5min. then restart and check level, in res do not open cap . feel air from fan and see if it is getting hot, this may take up to a half hour but do not drive,

A few questions, does this jeep have an electric fan?
when you heard the knocking was engine temp hot?
If you start jeep cold does engine knock?
Did this jeep get a new thermostat with waterpump job?
did it overheat when pump went bad and why did water pump get replaced?

sorry for all the questions ,just trying to get all the info to help you .

My trail blazer has something in the front end that is really growling. it started out just a slight noise, now it is really loud!! I don't feel anything like a wheel bearing being loose, just really loud.


Had the same problem in my 2004 Trailblazer. Finally figured out it was the air pump on the driver side right under the driver side floorboard. Took it off and it was full off water because of a design flow by Chevrolet. I took the pump off and emptied the water out and dried it out real good and the noise stopped. I re routed the intake for the pump away from the front of the truck and haven't heard the noise since.

89-98 chevy blazer


It's not worth doing all that conversion, buy the time you spend the time and money to convert the 89 4.3 to work on the 98 blazer, it would be cheaper to install a 98 vortec rebuild. The 89 4.3 have a TBI fuel injection system and the ecm on the 98 will not work and the bad news is that the ecm on the 98 also controls the transmission shift points and the 89 will not, so even if you swap the ecm to have the 89 4.3 engine work. the transmission will not shift. Sorry for the bad news but it would be cheaper to replace the 98 engine with the years of 1996 to 2001. Good luck and hope this helps.

My 97 Chevy blazer has a Immobilizer ; doesn't start.


I agree with gasitjr.
I own a 98 blazer. When you try to turn over the engine. Does the engine rotate? If yes,it's not the starter or the battery. When you turn the key into the ON position before it starts can you hear an electric motor noise winding up? If yes , the fuel pump maybe OK but if the pump pressure is bad...blazer wont start. Pump runs about 300 plus labor. I've done it..It sucks

98 chevy s10 blazer turn signal


Unplug the turn signal relay from the fuse box and start you engine. Does it still make that noise?
If yes... Put the relay back in, that is not the problem.
If No...Then the relay could be bad, replace it!
