Coolant hoses

[Subfixer]

I needed to replace my radiator, so "while I was in there" I figured I'd replace the coolant hoses as well.


I was able to locate the upper radiator hose, Bypass hose, and the short hose from the thermostat housing to radiator.


I can't seem to locate the "engine hose" that goes from the thermostat housing to the water pump.


I know Jerry has silicone hose sets, but I am looking for an original style Rubber hose (not used). Anyone know where I can get one?


How do you get that hose out? It's pretty crowded in there.


Thanks.

Last I looked Haibeck sells hoses for the LT5.

I'll give him a call. Thanks.

The engine hose goes from the back of the thermostat housing to the water pump. If you look from the passenger side you will see the hose. It curves up and over to the water pump and has a wire coil on the inside.

If you remove the oil filter you will have extra room to work on it.

I noticed when JVD installed the hose to the water pump side he used two clamps vs one to prevent it from leaking.

If you still need the OEM hose(s) send me a PM, I am sure I have a set.

Looks like this outfit may be able to help.

I've got a complete set of take offs from a 9,700 mile 91' if youre looking to "keep it stock" or NCRS. I've got a few NOS factory spring clamps too.

My 92 only has 22K miles, but the hoses are 28 years old..... Since things are apart, I wanted to replace with newer rubber.

Car had a bad oil leak at one time (oil cooler hose leak) and the lower hoses are oil soaked.

My 94 has 170,000 miles on it but heater hoses so far are fine. Oil soaked - not sure of degradation.

The weather finally cooperated this weekend. New coolant hoses installed, new thermostat, new Dewitts radiator.
Also replaced a leaking secondary vacuum switch, new vacuum check valve, replaced the DIS with a used spare (trying to fix a code 43 issue).
Plenum goes back on next weekend. I'll be taking the ECM to work this week to check for bad solder joints and the like.

Yup!
One good day, then back to cold and wet!
Did you get to go out for a drive?

[Subfixer]

Plenum is still off. maybe next weekend.

How’d ya do on the one that goes up
over the frame rail to the water pump?

[Subfixer]

With the radiator out and the fans out of the way, there was more room. Removed the belt tensioner and it was easy.

Finally all buttoned up. Took a short ride around the block while fully warmed up. No leaks, no Code 43 (yet).
