how to change the timing belt

Hello –

It looks like this guide has the instructions on how to change out the timing belt step by step

https://www.2carpros.com/diagrams/isuzu/rodeo/2004


Please run down these guides and report back.

Okay so my isuzu 3.2 v6 is all messed we replaced the timing belt and did like every thing that a machanic would do but still the cams dont match up with the moter when the moter reaches compression stage instead of both valves being closed exaust stays open no mater what we we cant get it to work please help !!!!

Put the engine no.1 piston on its compression/TDC and then line up the cam and crank shafts markings

The camshaft would tend to run away so you need to hold them in position while installing the belt.

I need to change water pump and timing belt, can you help me?

REMOVAL & INSTALLATION
CAUTION: This application may be an interference engine. DO NOT rotate camshaft or crankshaft when timing belt is removed, or engine damage may occur.

TIMING BELT

Removal

1. Disconnect negative battery cable. Remove air cleaner assembly. Remove upper fan shroud. Relieve tension on serpentine drive belt tensioner and remove serpentine drive belt.

2. Remove 4 cooling fan assembly mounting nuts and remove cooling fan assembly. Remove cooling fan drive pulley. Remove serpentine drive belt idler pulley assembly. Remove serpentine drive belt tensioner assembly.

3. Remove power steering pump with hoses attached, and set aside. Using Crankshaft Holder (J-8614-01) or equivalent, hold crankshaft from turning and remove crankshaft pulley bolt. Remove crankshaft pulley.

4. Disconnect harness connector from right side timing belt cover (if equipped). Remove timing belt covers in this order: right, left, then lower. Remove fan bracket (if equipped).

5. Rotate crankshaft to align timing marks. See Fig. 1 and Fig. 2 . When timing marks are aligned, No. 2 piston will be at TDC.

6. If reusing timing belt, mark belt with arrow to indicate original rotation direction. Also place mating marks on timing belt and camshaft sprockets for reassembly reference. Remove timing belt tensioner, and set aside with push rod facing up. Remove timing belt.

CAUTION: To prevent air from entering timing belt tensioner, tensioner rod must always face up.


Installation

NOTE: This information outlines the proper steps to index the camshafts with the crankshaft. in the event that camshaft timing has been disrupted, due to timing belt breakage or camshafts/crankshaft being rotated without a timing belt, this is important prior to timing belt installation. Due to the gear-ration used by each camshaft pulley to drive the camshafts, engine timing cannot be indexed conventionally.

To compress tensioner pusher, place in soft-jawed vice. Slowly compress tensioner pusher pin until it lines up with the two small holes in tensioner pusher housing. Insert a straightened heavy duty paper clip through holes in housing. This will hold the pin in it's compressed position.

IMPORTANT: In the following procedure, the references to 9 or 12 O'clock positions are based on deck plane of the cylinder deck-to-cylinder head mating surface (as viewed from the front of the engine), and NOT relative to the shop floor.

When replacing a head gasket we had to remove the timing belt. We cannot get it in time. We need to know how to time the engine and where the timing marks are located. We have tried multiple times to set this. One time the car spurted and popped. We realize there are marks to set this by but we have been unable to locate them.

Engines should be set at the timing position prior to any removal work, these are an interference type engine, that is if the valve timing is not set correctly engine damage may occur as the valves will strike the pistons and they will bend. See pic for correct alignment, but I do feel that if it was more than a few teeth out you have now bent valves in the head,

My timing belt was replaced and the guy that replaced it said the computer needed to be reset. It has no acceleration.

Hi there,

if the timing belt is replaced there is no need to touch the computer, i would be checking that he has set the valve timing when the belt was refitted first.

My water pump on my 98 Isuzu Rodeo Went out and i had to replace it, It is driven by the timing belt. I tried to mark it so that i wouldnt lose time on it, but either the top or the bottom is off by just a little it seems is there any helpful tips to help me get it back into time or am i screwed..

it would help if we had an engine size

Its a 2.2 5 speed 4 cyl

the car had the timing belt changed at 60000 miles by the dealer recall campaign. I had a local shop change belt all pulleys, tensioner and water pump at 136000 miles. looks like they used an aftermarket belt. the belt broke after 4000 miles. damaged valves when belt broke. repair shop can't tell me why belt broke ?

4,000 miles and timing belt breaks is a good sign of the belt being installed incorrectly or the belt had a flaw in it prior to installation. in either event there is no way to prove whos at fault

My 98 Rodeo overheats after about 20 mins of idling or 5 mins of driving, depending on the RPMs or speed. I have replaced the thermostat, water pump, radiator, radiator cap, clutch fan, serpentine belt, timing belt, timing belt tensioner, a few of the water hoses, and even the alternator to ensure proper power from the electrical system. I have put a lot of time and money into solving this issue, but I still have not resolved it. I am completely stumped as to why it is still overheating. Any help or suggestions would be greatly appreciated. Thanks.

have a pro pressure check the coolant system for a head gasket leak

Plug in a scan tool that can read actual temperature from the computer and compare it to what it says on the dash. May just be a bad temp sensor. Are you sure you are burping the air out of the system?

I have narrowed it down to either a blockage in the block, a bad head gasket, of a cracked head. There is no water in the oil but there is definitely moisture coming through the exhaust.

Does the moisture actually smell sweet like antifreeze? I would be sure to remove the radiator cap and really burp the system well. Raise the rpm a bunch even after the thermostat opens with the heat on just to make sure you have gotten all the air out.

I'm having trouble timing the engine after replacing the timing belt. I have matched up the marks on the belt with the marks on the pulleys and such, but it still runs rough and back fires. Ive pulled it apart and put it together 3 times, but still not right.

did the belt break during operation? if so than valves probably got bent because it is an interference style motor.

hey did u get ur vehicle running fine? i am experiencing the same symptoms, but did u set ur #1 at tdc? Mine is a 99 and the book tells me to set the crankshaft marking to match up with the oil pump marking and this makes my #2 piston a TDC..hope this helps u figure out your problem and help me figure my problem..

Had water pump & timing belt kit replaced in dec.2015.Driving fine till few days ago i lost complete power.new battery,cables,have spark,new fuel pump.cranks over but wont start.How would i know if timing belt jumped?

it probably hasn't but you can pull it apart to check to see if it's in time and that may not be the problem. scan for codes and check fuel pressure with a gauge auto parts rent it.do that first

Hi thanks for your response but fuel presure was checked and normal.and code reader is for cars 1995 and newer i thought

nope see pic for aldl which is behind lh kick panel count flashs each will flash 3 times 1 then 2 +code 12 which is normal.... any other code get back to us your blet could have slipped but I kind of doubt it as when a water pump is installed is usually a timing belt kit which includes new tensioner/pulleys /water pump

site still isn't working right see other reply as well

How do u check and adjust the timing? Just replace the head gaskets, got it all put back together and now it wont start. Fires up with starter fluid but dies when the fluid burns up.

ignition timing is controlled by PCM. ensure timing marks on belt are aligned properly. The timing belt on the 3.2 SOHC does not get installed at tdc#1 the crank pulley has a half moon cut-out that positions at 3oclock and the slots on the cam pulleys point at raised dots on the rear cover

Which way do I turn the pulley? The info was very helpful! Thank u!

the timing belt should have arrows of the correct direction , crank turns clockwise

Thanks! U have been a big help!!!

1995 Isuzu Rodeo Question 6 cyl
----------------------------------------------------------------
Hi,

My Timing belt blew while driving. We followed the Haynes book and replaced it. I lined up the Came shaft marks to the cover. The Crank Sprocket to it's marks. After putting it all back together. It won't start. It turns over but now the intake butterfly valve pushed air out instead of sucking it into the engine. Is the timing off? I ensured the # 2 Piston was TDC. Could something else be wrong Or was it operator Error (ME). Any help would be gladly appreciated.

Thanks.

Put the engine no.1 piston on its compression stroke/TDC then line all the timing markings

What is it a SOHC or DOHC 3.2L

Thanks,

DOHC, The book says No 2 Pistion. Should I do it on No 1. Willthat damage the engine?

ust set all the timing marks as you see below.

i'm doing a water pump on a 1994 Isuzu Rodeo, V-6. I got it in, but i had to pull the timing belt to getr to it. now its out of time. I know i need TDC on the #1 cylinder, my quesion is, is that only gives me one side. i have to time both camshafts together with the crankshaft, and i just don't know how to do it. any advise would be greatly appreciated. oh, and i struggled really badly at getting the belt back on. the tensioner seems to be sticking or something i'm doing is incorrect. that advice would help tremendously too !

you should use a new belt and the new belt should have marking on it it goes with relation to the pulleys like in this one note the dots
