Thread: UHF installation and chirpie sounds.

If you have a lower end model car it is possible to use an unused fuse location in the under dash fuse box.

Don't cut anything important but it makes for a more factory feel.

My GME Tx3200 is just double sided taped to the roof console. Been there a few years now.

Antenna is on front guard.

Hi guys,

ive had a look under the hood and found where the chirpie sounds come out of. seems to be on a tensioner (hard to find exactly where but im pretty sure the one shown on the pics). the thing that alarmed me is that it is attached to another part and there is a seal between that and the front of the engine. now this whole housing shakes with the tensioner at the seal part. see the photos. ive circled the pulley in red and the seal attachment in yellow. at the seal part seems to shake left and right as belt spins n the pulley/tensioner makes the chirpie sound (ie bearings).

any feedback would be great. do you guys think i should pull the whole bit off and change seal and pulley or just try n fix the sound. there seems to be nothing leaking out and the seal looks ok from what you can see. also if you could tell me what that part is and why its completely attached like that to the bracket which the pulley is on.

thanks guys

That's the serpentine belt tensioner. The sprung section has a rubber isolator which wears out, leaving metal to metal - there are no seals where you have circled. Best to replace the whole thing - been covered here before. Unit is made by Dayco (OEM) and available from Bursons and Repco for less than $100 (I think I paid around $93 earlier this year when mine was also found to be worn). This unit also causes the belt to be out of alignment when it is worn that much. Only takes a few minutes to replace - belt off, then the centre bolt, might as well get a new belt while you are there as the one you have looks a bit marked up.

Try spraying some WD or lube on the sprung unit (not on the belt) and see if the noise goes away or changes - just to be sure before you replace it.

That's a very clean looking engine bay by the way, looks new.
Might also look in to getting that black radiator overflow bottle replaced at some point before it fails you. Simon

hi simon,

thanks for the post. i will do what you suggested. also, why would the overflow need replacing? do you see something wrong with it? it seems fine to me, is there a problem with these?

The black overflow bottles are prone to failing, the clear replacements are much stronger. Might look ok but it could fail a long way from home. Do a search on this too, plenty of failures and warnings to read about, mine cracked at the bottom and I lost a lot of coolant. Simon

My black one cracked, dumped the water and cooked my engine. New engine was required. Get rid of it and get the white one ASAP. Cheap insurance.
