How to replace hood latch that does not latch tight no more

latch has bolts, mark position before loosing bolts, remove and replace aligning back up with lines, tighten but not to tight, slowly close and then open to check fit

close hood and lift up on hood to see if it stays closed.
if not, check inside car to see if latch(that you pull) is in the correct position. you can tell when hood is closed that there will be some tension on latch.
check under hood, where hood closes on latch of hood, is tight and secure(no loose bolts)
also check cable if broken.
only those things can cause hood to pop open.
if all visual inspections check out and still continues to open while driving then the latch (the mechanism that hold the hood down) is bad. vibrating while driving will cause it to open.

there should be adjustment posts on the hood, you could raise those or lower the latching mechanism.

you might also be able to adjust the glove box latch to close tighter

I am not familiar with this particular car, however MANY times I have opened a hood by having one person hold the lever up (or out), while another presses down or hits with a closed fist, the hood near where it latches. After you get it open, thoroughly clean and lubricate the latch mechanism. I hope this helps you get in.

sometimes the hood adjustment for the latch is too tight, pull the hood latch, go out to the hood and press down on it at the latch location, push hard and release quickly, then adjust the latch before closing hood

Tap on hood should pop up, then lube latch.

In the front of the hood latch ( to the left and right of the unit) there are two mounting screws that actually hold the hood latch piece together. If those screws are loosened the latch can be moved left and right. Align the latch piece to the hood to make sure the hood catches.As long as the latch itself will work by pushing it down this works and it also helps with tight tension issue on the pull chord from inside of the cab.

can you reach the cable itself?,or is it broke at the hood latch?IF its not broken at the outside latch, try to follow the cable,un-hook it from the handle and pull on the wire cable to open it.IF its broken at the latch itself,you are going to have to reach the latch through the grille and try to pull the lever the cable connects to.That part is no fun at all..!!

need to spray lube on latch asy under hood.and manualy operate the latch a couple of times.

Yes! That is the purpose of those rubber guides. They actually should be half compressed when hood is latched. Many cars have adjustments for these!
