Have any of you gone through the cooling system troubleshooting flow chart in the TM9-2320-280-20-1 manual? Starting on page 2-164 you'll find a flow chart that walks you through the steps to diagnose problems with your cooling system. It's written so the average mechanic can follow the steps...

Look around on the evil auction site, and the various HMMWV groups on fakebook where it’s not uncommon to find the set (box plus sender) for under $400. Easier to find around $500, if they’re asking much more than that, keep looking. I paid $490 shipped about 2-1/2 years ago - yes, it fixed...

My wife and I are in (but alas, the HMMWV is not). We'll be coming up Friday evening and heading out on Saturday around noon. Transmission is still up on the stand with too many major assemblies in bad shape. It's definitely far beyond just replacing seals and clutch friction plates like...

Yeah, just wanted to mention it doesn't seem to be slipping at all now in any gear. That issue hit immediately, not over time. I was out for a weekly short drive to exercise it and all of a sudden it started slipping. Luckily I made it one block to my father in law's house. It went from feeling...

Very nice HMMWV. Sounds like you have a plan. If it's the fourth and reverse clutch, try not to use reverse any more than you have to if you plan to re-use it.

That will all keep you busy a while. When I replaced my entire steering linkage (just not the gear box) I ordered pitman and idler from HummerPartsGuy and am very happy with his customer service, FYI. He charges more than scrounging surplus off eBay, but he provides plenty of advice by email...

Inspection day! I went to replace the front shackle brackets and found out that with the newer revision of parts, the original bolts weren't long enough... that's going to be on order. But yes, inspections. I decided to look under the HMMWV. Pretty easy to see: an obvious class 3 leak from...

Yes, thank you. From what understand, have a complete 'old style' serp setup, with the big cast alt / ps pump bracket. Found a clutch-pulley and am going to attempt to modify the alt mount to make it work with the old serpentine system. 603 water pump is the last revision of the high-flow 6.5L...

In the middle of a serpentine conversion on my CUCV using what think are 'early' HMMWV parts, including 200amp 12/24V alternator and the big cast bracket with integrated p-pump mount. Wondering if can add a pulley with a clutch to this alternator. SS member bought parts from said he didn't think...

Likely the Cadillac valve (on a HUMMWV?) used to control the fan clutch. It's the normally golden color, round thingie out in front of the windshield, under the hood, drivers side. When by-passing fluid thru internal design, makes a hyper sonic "hissing" further amplified by where / how it is...

Hello everyone, cheers from Brazil! I have a 1986 M998, with 6.2 and 3 speed for 4 months now (all fluids changed and hubs checked). While daily driving yesterday, it started loosing power as if there was a "clutch" problem or something similar. Revs went up but it would move slower and slower...

Few parts to clean out. Mostly for the big trucks - NIB - Transfer Case Input yoke for HET - Oshkosh 55000 Case - # 6.5-4.2561-1x - $180 shipped used - Transfer Case input yoke for HEMTT - Oshkosh 55000 Case - #6-4-6761x - $100 shipped NOS - main shaft slip yoke for M915A2 - M916A1/2 -...

Interested in the MRAP winch, will send PM for more details

Thanks NDT, I remember that thread. That's where I got the info for the 195 switch. Action: I replaced the thermostat to a 180 and temp switch to keep the engine below 200 deg. I spent too much money on the GEP engine to loose it to a cracked block because it got too hot. I know there are...

Does the winch have the controller?

I am bringing a few things. I have a complete NOS hmmwv underbody protection kit. I have an 18k warm industrial MRAP winch. It has the air setup to lock the clutch in and out via the cab. Great for the 5 ton guys that want a winch. $550 I am going to clean out the shed and see what else i...

I was thinking the same thing. Thermostat needs to be replaced. Ensure that you by the Hummve specific high flow one. Also nothing wrong with disconnecting the TDM as part of trouble shooting. If fan turns on then TDM or Thermostatic fan switch are bad. otherwise it's the Thermostat Sent from...

5 minutes Of idling and it over heats is a bad thermostat, not a non-working fan clutch system, not that the fan clutch system does not need to be fixed before you go driving. Folks need to understand how cooling systems work, this is not specific to the hmmwv. Even a faulty coolant reservoir...

Sounds like your fan system is not right. Easiest check is the temp sensor wires, per TM, the sensor that is near the thermostat. Then check the Cadillac valve, also called the valve solenoid (some are marked Cadillac manufacture, hence the nickname). You might also check your fan is not...
