Are there TWO PHH's??

[airlaird]

Folks, I am perplexed.....I have my truck being worked on by an incredible mechanic who works only on LC's. While he is putting a new valve cover gasket and spark O rings..he is doing my PHH...for a mere $50.00 bucks. I supplied him with the Blue PHH kit and he calls me and says...where is the other hose?? .........( sound of wind gently blowing through a the still night....
WHAT is he talking about?? There has NEVER been any mention of a secondary hose needing replacement along with the PHH. He explained it to me but I was sitting in a helicopter shutting down and could not hear very well....what is he talking about??

He's not describing the PHH.

Well...he is a Toyota certified mechanic and knows the LC inside and out...there is no way he is talking about the wrong hose. He mentioned another hose that is near it...he is not saying it is another PHH...(that's my phrasing) but he is insinuating there is another hose that should be replaced. What it could be I don't know...I'll be there tomorrow.

The PHH/FHH kit I bought has two hoses in it, which is probably confusing him. The other ones of the same diameter are on top of the engine in plain view. I think there are two on top and the one PHH below that are all the same diameter.

He is talking about one of the throttle body bypass hoses.

Two preformed 3/8" diameter hoses that route coolant through the throttle body to prevent it from icing up in winter.

One runs from the top tank of the radiator to the throttle body, the other from the throttle body down through the intake manifold and connects to the head near the PHH.

IMO a good idea to replace them, but not as much of a necessity as the PHH. I replaced mine when I did my PHH, FYI.

THANKYOU...I'm sure that's it....why in the heck isn't a two piece sold by you know who ) I had never heard of this before and now I need a second silicone hose!!

I think that is an OEM preformed hose. Please post if you found a silicone hose for it.

One runs from the top tank of the radiator to the throttle body,

sorry to nit pick small details but that one actually runs from the TB to the thermosat housing, the one that goes to the top of the radiator comes from the main water outlet, at one point the two run right next to eachother,

I kinda thought he might be talkin' about the pair of "firewall heater hoses", which you can order from the PHH guy also.

If your mech is yakking about a smaller diameter one with that joins the head next to the PHH, tell him not to worry about it unless it's obviously distressed. It is indeed a preformed Toyota hose, and not subject to the stress the PHH is. Don't bother replacing it or worrying about it. I replaced both of mine at around 150k and neither showed any cracking or deterioration - even on the inner surface (cut them open out of curiousity).
